HI98594 is a portable logging multiparameter system (meter and probe) that monitors up to 14 different water quality parameters (7 measured and 7 calculated) such as pH, ORP, turbidity, conductivity, dissolved oxygen and temperature. The HI98594 features a graphic, backlit display that automatically sizes the digits to fit the screen with on-screen graphing capability. Each parameter is fully configurable.
The HI98594 was designed to withstand harsh environmental conditions and is ideal for field measurements. The meter meets IP67 standard (30 minute immersion at a depth of 1 m) and the multi-sensor probe is totally sealed against water and dust, and meets IP68 standard (continuous immersion in water). The meter incorporates a dual charging system, utilizing a rechargeable Li battery and backup alkaline batteries to extend field use.
The meter can log data that can be easily downloaded as a CSV file or graph using Bluetooth® wireless technology to Hanna Lab on iOS and Android devices or to a PC using a USB type A to C cable.
