Overview
The HANNA HI839800-02 microcomputer digestion heating processor is made of heat-resistant and corrosion-resistant materials, which can digest 25 samples at the same time. The preset COD and total phosphorus digestion temperature is 150 ° C, and the total nitrogen is 105 ° C. It is equipped with status indicators and LCD display, and supports pen thermometer inspection temperature. Timer Range 0 to 180 minutes or continuous digestion, with buzzer prompt and overheat protection.
Features
1. Low temperature alarm function: prompts that the temperature is lower than the set value during the heating process.
2. High temperature alarm function: automatically adjust and alarm when the temperature is higher than the set value.
3. Timing function: The remaining time is displayed during the heating process until the end of the timing.
Principle
The heating process is controlled by a microcomputer, and a specific temperature (e.g. 150 ° C or 105 ° C) is preset for sample digestion. The temperature is monitored during heating, and if it is lower or higher than the set value, an alarm or automatic adjustment is triggered to ensure temperature Stability. A beep is issued after the timing is over, and the heating device is automatically turned off with overheating protection.
Applications
COD digestion, total phosphorus digestion, total nitrogen digestion
Steps
1. Connect the power supply (AC230V, 50Hz).
2. Set the digestion temperature (105 ° C or 150 ° C).
3. Set the timing time (0-180 minutes) or select the continuous digestion mode.
4. Start the heating and observe the LCD display and status indicator.
5. Use a pen thermometer to inspect the temperature.
6. Wait for the timing to end the beep prompt or stop manually.
Notice
• Ensure that the Ambient Temperature is used in the range of 5 ° C to 50 ° C.
• Warm-Up Time takes 10 to 15 minutes, depending on the temperature.
• Pay attention to the high temperature alarm to avoid burns.
• Regularly check temperature accuracy and Stability.
• Clean in time after use to maintain corrosion resistance performance.
