727 MIKROKERA 4L HYDROGEN SULFIDE SENSOR

727 MIKROKERA 4L HYDROGEN SULFIDE SENSOR

SENSOR FEATURES
  • Reliably detects H2S at concentrations from 0.15 to > 100 ppm
  • Rugged sensor operates at temperature and humidity extremes
  • Fast response (<5 seconds) and complete recovery after H2S exposure
  • Sensor response is stable (does not go to sleep)
  • Thermistor heater allows active control of sensor temperature based on environmental temperature
