Principle
The acetonitrile detector adopts the principle of catalytic combustion detection and detects CH3CN gas by diffusion Sampling method. The detector converts the gas concentration signal into an electrical signal output, and supports various signal output methods such as 4-20mA, RS485, and switching quantity.
Steps
1. Install the detector to the designated location
2. Connect the power supply and signal cable
3. Set the alarm value, zero adjustment, calibrating and other parameters through the remote control
4. Start the detector for gas concentration monitoring
5. View the inspection data through the display screen or remote device
