COD Test Tube Heater
The HI839800 COD Test Tube Heater features two predefined temperature profiles: 150ºC and 105ºC. Digestions for chemical oxygen (COD) and total phosphorus are conducted at 150ºC, while total nitrogen digestions are conducted at 105ºC. The test tube heater automatically heats up to the set temperature, holding it until the countdown timer has finished. Once the timer has ended, a beep will sound and the heating element will turn off. The outer casing of the HI839800 remains cool to the touch, even during a timed digestion. An optional lab safety shield and test tube cooling rack provide a complete setup for sample digestions.
