Description
- Low temperature alert appears when the block is warming up. It alerts the user that the temperature is below the set value.
- High temperature alert appears when the block is warming up. It alerts the user that the temperature is above the set value.
- 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: 150°C and 105°C. COD and total phosphorus digestions are conducted at 150°C, and total nitrogen digestions are at 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.
Block temperature is continuously displayed on the LCD even when there is no active temperature program running.
