fixed chlorine gas detector

fixed chlorine  gas detector    Brief Introduction TGas-1031 on-line gas transmitter which adopts high performance sensor unit can continuously measure the concentration of gas on site and convert the concentration signal into digital or analog signal output(4-20mA analog signal,RS485 communication signal and switch quantity alarm signal to transmit remotely and drive). Main Features u  Two kinds of optional mode of power supply, including centralized busbar type and independent area type u  High and low concentration alarm, performing real-time monitor to gas u  Anti-poisoning type gas sensor with high sensitivity u  Automatic modification of ageing curve of sensor, keeping constant alarm sensitivity u  Function of automatic recognition of sensor trouble, function of high concentration gas above-norm of sensor u  Function of automatic detection at starting up, and it has advanced function of self-diagnosis and self-reparing u  The calibrated concentration value is adjustable, facilitating users to set by themselves Technical Parameters
