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.
The reactor is 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
Key features
- 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
- To operate in infinity mode, the timer can be used without the shut-off feature
- Visual power indication
- Green LED indicates power on
- Blinking red LED warns if heater exceeds 50°C
- Yellow LED indicates heating is active
- For optimum safety, the block heater should always be used with a safety shield or other physical barrier placed between samples under test and operator
Accessories
- Stainless steel test tube rack to hold 25 COD tubes - HI 740216
- Bench top safety shield for use with HI-9800 series COD reactor/digester - HI 740217
