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

HEALTH & SAFETY
FUNCTIONAL DESCRIPTION
Before unpacking, setting up or using this reactor it is important to carefully read this manual. Pay
particular attention to all warnings, cautions and notes. Failure to do so could result in serious injury to the
operator or damage to the equipment.
To ensure the safe use of this reactor, it must not be installed or used in any manner other than that
specified in this manual.
Reactor Operation: The Reactor incubates glass vials containing hazardous chemicals at high
temperature. Read the Material Safety Data Sheet (MSDS) before handling reagent vials.
Handling Reagent Vials: Handle the vials very carefully and wear protective clothing. After use, dispose
of the reagent vials according to local regulations.
Safety Equipment: When operating with Reactor use protective clothing, including goggles or face mask,
and gloves.
Use of the optional safety shield is highly recommended.
Reagent Spills: Wipe up spilled reagents immediately. If reagent contacts skin, rinse the affected area
thoroughly with water. Avoid breathing released vapors. Read the Material Safety Data Sheet (MSDS) for
each reagent for complete chemical information.
Fire Hazard: Avoid the presence of flammable liquids or paper near the operating Reactor. A fire hazard
could be created.

REACTOR DESCRIPTION
1) Heater block:
2) POWER LED indicator: lights (green) when the power switch on the back of the reactor is set in the ON
position.
3) HOT surface indicator: flashes (red) if the block temperature is above 50°C.
4) HEATING LED indicator: lights (yellow) only when the heater is ON. When the indicator cycles ON and
OFF, the heater is maintaining a stable temperature.
5) ▲, ▼: keys are used to adjust the timer values when setting reaction time.
6) 105°C/150°C: key is used to select the temperature program, 105°C or 150°C (221°F or 302°F).
7) START: key is used to start the selected temperature program or to start the timer after placing the
vials into the heater block.
8) STOP: key is used to stop the heating process or to stop the timer.
9) Liquid Crystal Display (LCD)
10) Power switch: turns the reactor ON and OFF. When the power switch is set in the ON position
the power indicator will light.
