Chemical oxygen consumption is one of the control items of environmental water quality and wastewater discharge. It is an important comprehensive index of water organic pollution. The instrument overcomes the shortcomings of the original cod reflux device, such as large floor area, power consumption, water consumption and inconvenient operation.
Product features
1. Ambient temperature ＜ 40 ℃
2. There is no strong heat source or strong corrosive gas around.
3. Shock and vibration shall be avoided
4. Reliable ground wire shall be provided
5. Check whether the heating pipe is broken
6. Insert the attached thermometer into the temperature measuring hole
7. Plug in the power plug and turn on the power switch. At this time, the instrument screen displays the current measured temperature. When the heating indicator is on, the instrument is heating. Press the setting key, and the screen flashes to display the current indicated constant temperature. Use the keys and keys to modify the constant temperature. After modification, press the setting key again to save the new set value. The constant temperature will not change during the setting process. If the key is pressed within 30 seconds under the setting state, the instrument will automatically exit the setting state and keep the set constant temperature unchanged
Note: due to good thermal insulation, if the temperature is higher than the set temperature, the temperature drops very slowly. After modifying the set temperature, it may take a long time to reach the newly set constant temperature and remain stable
