GENERAL DESCRIPTION

The 

HI 839800

 thermo-reactor is constructed of durable materials with a vial capacity to perform up to 25

digestions simultaneously.
The reactor is equipped with 2 predefined temperature programs (dedicated temperature settings for COD
and total phosphorous reactions at 150°C, and also 105°C for total nitrogen digestion).
In addition, 

HI 839800

 features LED indicators for visual indication of power on (POWER), heating in

progress (HEATING) and hot surface warning (HOT).
The heater block temperature can be verified by placing a thermometer in the temperature well in the block.
A 3-hour timer is incorporated for applications where timed digestions are required. When this feature is
enabled, a beep will be heard and the heating element will turn off at the end of the selected time period.
The reactor contains a thermal fuse that prevents overheating, by turning off the heating element.
The temperature is continuously displayed on the LCD even when there is no active temperature program
running.
Two models are available:

• HI 839800-01

 runs with 115 Vac power supply

• HI 839800-02

 runs with 230 Vac power supply
