DESCRIPTION

Easy and Simple:

The COD heating block features two preset temperature profiles: 150ºC and 105ºC. Chemical oxygen (COD) and total phosphorus digestions are performed at 150ºC, while total nitrogen digestions are performed at 105ºC. The HI839800 automatically heats to the set temperature, maintaining it until the countdown ends. Once the timer ends, a beep will sound and the heating element will turn off. The HI839800's exterior remains cool to the touch, even during timed digestions. A lab safety shield and optional test tube cooling rack provide a complete setup for sample digestion.

Temperature alerts:

The HI839800 standard alerts users if the heating block temperature is higher or lower than the set temperature. A timer icon reminds users to wait for the heating block to cool or warm before inserting their samples.

Built-in timer:

A built-in countdown timer of up to 180 minutes allows users to easily set the required digestion time by simply pressing the up and down arrows. Once a time has been set and the heating element is stable, pressing the START button begins the digestion procedure.

Status indicators:

There are three LED indicators on the HI839800. A green LED indicates that the heater has been turned on; a yellow LED indicates when the heater is actively heating to a set temperature; and a red LED indicates when the heater exceeds 50ºC, reminding the user that the aluminum element is hot.
