A benchtop pH and conductivity meter is a laboratory instrument designed for stationary use on a lab bench. Unlike handheld or portable testers, benchtop meters offer larger displays, more stable readings, and advanced features such as multi-point calibration, data logging, and PC connectivity. These instruments measure two of the most commonly tested water quality parameters: pH (the acidity or alkalinity of a solution) and electrical conductivity (EC), which indicates the level of dissolved ions in water.
Hanna Instruments manufactures a full range of benchtop meters for pH, conductivity, dissolved oxygen, ORP, and ISE measurement. Whether you run a water treatment facility, a food production line, a pharmaceutical QC lab, or a university research department, Hanna has a meter built for your application. Every meter is backed by Hanna’s warranty and service program and supported from our Singapore office.
Hanna Instruments offers a wide selection of pH and ORP Benchtop Meters. These systems respond to a complex range of measurement and monitoring requirements, providing accuracy, reproducibility, and reliability.
Hanna Instruments offers a range of Benchtop Ion Selective Electrode (ISE) meters that allow for precise measurement of ions in a variety of applications. These meters are designed for accuracy and ease of use, with features such as automatic calibration, data logging and pH compensation. Our Benchtop ISE meters are suitable for use in laboratories, research facilities, industrial applications and educational institutions.
Hanna Instruments offers a wide selection of pH and ORP testers. Choose from the latest pHep to the iconic Checker® that has been used in schools all over the world. Available options include testers with replaceable electrodes, multi-level LCD, or the Piccolo® that has an amplified probe, making it immune to electrical noise interference. Versions with multi-level LCDs not only display temperature along with pH or ORP, but also have indicators for instability, calibration, and battery level.
edge meters offer many advanced features including automatic calibration and automatic temperature compensation of readings. All edge meters have a Good Laboratory Practice (GLP) mode to review calibration information include the data and time of the last calibration. The edge meters can log data and transfer data through either a USB port for a flash drive or a micro-USB port when connected to a computer.
For pH measurement, the edge meters offer CAL Check. The CAL Check feature identifies potential problems during the calibration process, such as clean the electrode, check the buffer for contamination, and the overall “health” condition of the electrode. For pH the edge meters are available as a dedicated and Bluetooth version for pH only and a multiparameter version that can accept either a EC or DO probe.
For EC measurement, the edge meters offer automatic temperature compensation and range selection. The edge meters are also able to measure TDS and salinity. The edge user can set the EC to TDS conversion factor, temperature coefficient, and type of salinity to be measured. For EC, the edge meters are available in a dedicated version for EC/TDS only or a multiparameter version that can accept either a pH or DO probe.
For DO measurement, the edge meters offer automatic temperature compensation and manual selection for altitude and salinity compensation. For dissolved oxygen, the edge meters are available as a dedicated version for measuring only DO or a multiparameter version that can accept either a pH or EC probe
The HI2000 Series are basic benchtop meters that have many routinely used features, including automatic calibration and automatic temperature compensation.
For pH measurement the HI2000 meters include a version with CAL Check. The CAL Check feature identifies potential problems during the calibration process.
Problems include electrode cleanliness, buffer contamination, and the overall “health” condition of the electrode.
For EC measurement the HI2000 meters include a meter available that has automatic temperature compensation and range selection.
The meter is also able to measure TDS and salinity
Portable meters are great for fieldwork, but benchtop meters are the better choice when accuracy, repeatability, and data management matter most. Here is how the two compare:
Feature | Benchtop Meter | Portable Meter |
Accuracy | Higher (up to ±0.002 pH) | Good (±0.01 pH typical) |
Display | Large LCD, multi-line readout | Compact screen |
Data Logging | Up to 1,000+ records with USB export | Limited onboard storage |
Calibration | Up to 5-point automatic with CAL Check | 1 to 3 points typical |
GLP Compliance | Full GLP data with date/time stamps | Basic or none |
Best For | Labs, QC, research, production lines | Fieldwork, spot checks, remote sites |
If your testing happens primarily at a fixed location and you need traceable, documented results, a benchtop meter is the right investment. For field applications, consider our portable meters instead.
Hanna offers several product lines of benchtop meters, each designed for different levels of complexity and different budgets. The table below summarizes the main series to help you find the right fit.
Series | Parameters | Key Features | Best For |
pH, ORP, EC, TDS | Automatic calibration, automatic temperature compensation, CAL Check on pH models | Routine lab work, education, budget-friendly setups | |
pH, EC/TDS/Salinity, DO (multiparameter) | Ultra-thin tablet design, digital electrodes with built-in microchip, USB data export, GLP mode, wall-mount option | Labs needing space-saving design and flexibility | |
pH, ORP, EC, DO | Advanced calibration, colour LCD, extended data logging, PC connectivity | Research labs, pharmaceutical QC, advanced industrial testing | |
pH/mV, pH with printer | Built-in impact printer (HI122), manual calibration option (HI2209), five-point calibration | Regulated environments needing printed records |
pH measurement is the foundation of water quality analysis. Hanna’s pH and ORP benchtop meters range from basic models like the HI2210 (0.01 pH resolution, automatic 2-point calibration) to research-grade instruments like the HI5222 (two-channel input, ISE capability, 0.001 pH resolution). All pH benchtop models accept standard BNC-connected electrodes and include automatic temperature compensation (ATC).
Hanna’s exclusive CAL Check feature is available on select models. CAL Check monitors electrode condition during calibration and alerts you to problems such as a dirty electrode, contaminated buffer, or an aging sensor that needs replacement.
Conductivity measurement tells you how well a solution conducts electricity, which is directly related to the concentration of dissolved salts, minerals, and ions. Hanna’s EC, TDS, and salinity benchtop meters use four-ring platinum conductivity probes that resist polarization and provide stable readings across a wide measurement range.
The edge HI2030 is a popular choice for labs needing conductivity, TDS, and salinity readings from a single instrument. It features automatic ranging, a user-adjustable EC-to-TDS conversion factor, and a selectable temperature coefficient. The HI2003 is a dedicated conductivity meter for users who do not need pH or DO measurement.
Dissolved oxygen (DO) is a key parameter in environmental monitoring, aquaculture, and wastewater treatment. The edge HI2040 measures DO with automatic temperature compensation and allows manual adjustment for altitude and salinity. The HI6000 series also includes advanced DO benchtop meters with both polarographic and optical (opdo) probe options.
If your lab measures more than one parameter regularly, a multiparameter benchtop meter saves space, cost, and complexity. The edge series is built around a multiparameter concept: start with a pH meter (HI2020), EC meter (HI2030), or DO meter (HI2040), then add probes for the other parameters as needed. All edge meters accept pH, conductivity, and DO digital electrodes through a single 3.5 mm connector.
For labs measuring specific ions such as fluoride, nitrate, chloride, or ammonia, Hanna offers ISE benchtop meters with direct concentration readout, automatic calibration, and pH compensation. The HI5222 is a two-channel research-grade meter that handles both pH and ISE measurements simultaneously.
Selecting a benchtop meter comes down to four main considerations:
Every benchtop meter requires regular calibration to maintain accuracy. Hanna manufactures a full line of calibration solutions including pH buffers (4.01, 7.01, 10.01) and conductivity standards (84 µS/cm, 1413 µS/cm, 12.88 mS/cm). All solutions are NIST-traceable and come with a Certificate of Analysis.
Replacement electrodes and probes are also available for every Hanna benchtop meter. For conductivity measurement, the HI763100 digital four-ring platinum probe is the standard electrode used with edge series meters.
Hanna benchtop pH and conductivity meters are used across a wide range of industries in Singapore and Southeast Asia:
A pH meter measures the hydrogen ion concentration in a solution to determine how acidic or alkaline it is. A conductivity meter measures the ability of a solution to conduct an electrical current, which reflects the total dissolved ion content. Many Hanna benchtop meters can measure both parameters when paired with the appropriate electrodes.
For pH, calibrate at least once daily before use, or more frequently if measuring across a wide pH range or working with demanding samples. For conductivity, calibrate weekly or whenever you change the probe. Models with CAL Check will alert you if calibration quality has drifted.
Yes. The edge series is modular by design. If you own an edge HI2020 (pH meter), you can purchase the HI763100 conductivity probe separately and plug it in. The meter will automatically recognize the probe and switch to conductivity mode.
CAL Check is a Hanna-exclusive feature that evaluates the health of your pH electrode during calibration. It checks electrode slope and offset values and alerts you to issues such as contaminated buffers, dirty electrodes, or sensors that have degraded over time. This helps prevent inaccurate readings before they happen.
Hanna pH meters with standard BNC connectors will accept most third-party pH electrodes. However, the edge series uses proprietary 3.5 mm digital electrodes with built-in microchips. These digital probes store calibration data and are designed specifically for edge meters.
