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: 150°C and 105°C. COD and Total Phosphorus digestions are conducted at 150°C, and Total Nitrogen digestions are at the 105°C. 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 50°C), 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. The temperature of the block is continuously displayed on the LCD even when there is no active temperature program running.
