Testermeter-HFT-C2H6O+HFM-301（1 channel gas controller+Fixed ethanol gas leak detector）alcohole detector ethanol leak detector
Single and Double Alarm Controller Technical parameters of the system
1. Detection Principle: The system provides 24V standard DC voltage to external transmitter, collects input signal of standard 4-20mA transmitter, and performs digital display and alarm operation through analysis and processing. 2. Applicable object: The system supports input signals of standard transmitters. Such as gas transmitter: carbon monoxide, hydrogen sulfide, hydrogen, sulfur dioxide, ammonia, oxygen, chlorine and combustible gas and other gas transmitters. Table 1 is the setting table of the above gas technical parameters (for reference only, users can set parameters according to specific conditions). |
