Product Description

Online carbon monoxide CO alarm system 0-1000ppm TGas-1031

Main features

♦ Two kinds of optional mode of power supply, including centralized busbar type and independent area type

♦ High and low concentration alarm,real-time monitoring

♦ Anti-poisoning type gas sensor with high sensitivity

♦ Automatic modification of ageing curve of sensor, keeping constant alarm sensitivity

♦ Function of automatic recognition of sensor trouble, function of high concentration gas above-norm of sensor

♦ Automatic detection when starting up,with the function of self-diagnosis and self-reparing.

♦ The calibrated concentration value is adjustable, facilitating users to set by themselves

♦ Before the sensor loses the function of monitoring alarm because of ageing, the detector is capable of automatic recognition and alarm, so it can effectively avoid missing report.
