The HI839800 is a robust, 25 vial capacity thermo-reactor for COD determination of industrial wastewater. The reactor has three stored and three programmable (custom) temperature programs.

The stored programs support analysis methods at:
· 170 °C (COD methods)
· 150 °C (COD methods, Iron Total, Phosphorus Acid Hydrolyzable, Phosphorus Total methods)
· 105 °C (Chromium (VI) and Total, Nitrogen Total methods)

• Flexibility in supporting applications that require custom programs (time and temperature)

• Laboratory safety shield included
· The included safety shield is highly recommended to use during vial digestion procedure to maintain a safe working environment

• Reactor block temperature continuously evaluated and displayed

• Built-in countdown timer
· A timer of up to 180 minutes is included for applications that require timed digestions. The end of the digestion time is signaled by 5 short acoustic beeps and “DONE” message is displayed. The heating is turned off and the block begins to cool off.

• Status indicator lights
· POWER (on)
· HOT (surface)
· HEATING (in progress)

• Overheating prevention

• Reference temperature probe well
· A small temperature well can accommodate a temperature probe, useful for verifying the heating block.

• Warnings and error messages
· The instrument displays warning messages when erroneous conditions appear and when values are outside the expected range such as high or low temperature, hot surface, or heating system malfunction.
