Features TGAS-1031 gas detector
- There are 2 power modes, which can be centrally or independently powered
- High and low level alarm relay output in real time
- High sensitivity and anti-intoxication sensor
- Sensor specialty self-repair device, keeping alarm constants and sensitivity
- The device automatically records sensor errors and over-strip errors
- The device enables intelligent calibration by changing the concentration of the standard gas
