Descriptions

The Hanna HI-839800 thermo-reactor is an easy to use test tube heater with the capacity to perform up to 25 simultaneous digestions. Complete with a countdown timer, it can be used for timed or infinity testing procedures. Robust and durable, the main body is machined from a single block of metal. Temperature within the block is controlled using a sophisticated electronic thermostat and can be verified by placing a thermometer in the temperature well provided.

Equipped with 6 pre-defined and 2 user-defined °C profiles.
Dedicated temperature profiles for COD and total phosphorus reactions are pre-set to 150°C
The total nitrogen analysis temperature is pre-set to 105°C
In adjustable temperature mode (50 to 150°C), the heater can be used for other samples that require different digestion temperatures
Heater block temperature is continuously evaluated and displayed on the LCD
Low temperature alert indicates that temperature is below set value
High temperature alert warns when temperature rises above the set value
Reactor has a thermal fuse that prevents overheating by disabling the heater
Countdown timer shows time remaining until heating element shuts off
A three hour countdown timer is ideal for timed digestion
The sound of a 'beep' indicates when the timer has expired and the heating element turns off
