- Countdown timer shows time remaining until the heating element shuts off.
The HI 839800 COD reactor is constructed of durable materials. The aluminum block incorporates a 25-vial capacity and a well for a reference temperature probe.
The HI 839800 COD reactor is an easy to use test tube heater. Its well-marked user interface provides intuitive operation. The reactor is equipped with two predefined temperature settings: 150º and 105ºC. COD and total phosphorus digestions are conducted at 150ºC, and total nitrogen digestions are at the 105ºC.
In addition, the HI 839800 has 3 LED’s for visual indication. A green LED indicates power, a blinking red LED warns the user of a hot heater block (above 50ºC), and a yellow LED indicates heating.
A three hour countdown timer is also incorporated to control timed digestions. When the countdown timer expires, a beep will sound and the heating element will turn off.
The reactor contains a thermal fuse that prevents overheating by turning off the heating element.
Block tempertaure is continuously displayed on the LCD even when there is no active temperature program running.
HI 839800-02 (230V) is supplied with power cable and instructions.
