Detail:
Indoor gas detector gas sensor by the gas sensing device outside the gas by inhalation when tested Outside gas leak, by the transmitter within the sample for processing the sensor output and ambient gas concentration corresponding to 4 ~ 20mA current signal or Modbus digital signal.
Sensors measure: combustible gas (100% LEL); toxic gas (ppm)
Combustible Gas Detector (% LEL) - used to measure the concentration was lower than the low calibration gas when the target explosive limit (LEL) of combustible gas.
Gas detector is used to detect the atmosphere gases (PPM). Detect carbon monoxide and hydrogen sulfide, etc.
