  • Expected Life: 10 years
  • Working Temperature: -20~50℃
  • Humidity at Work: 15~90%RH
  • Working Pressure Range: 0.1MPa±10%

Technical Description:
The MST141 electrochemical hydrogen sensor operates as a fuel cell-type sensor where hydrogen and oxygen undergo redox reactions, generating a current proportional to the hydrogen concentration, as per Faraday's Law.

Additional Parameters:
  • Recommended Load Resistance: 1KΩ
  • Offset Voltage: No requirement

Cross-Sensitivity Characteristics:
The sensor's response to interfering gases at 25˚C shows minimal cross-sensitivity, with hydrogen sulfide, sulfur dioxide, and nitrogen dioxide having equivalent hydrogen concentrations of less than 30ppm.

Installation and Usage Notes:
  1. Wires can be soldered during installation, but solder must not contact the sensor.
  2. Power-on aging time should be at least 30 minutes.
  3. Avoid long-term exposure to organic volatile solvents.
  4. The environment for operation or storage must not be acidic or alkaline.

MaiYa  MST141 H2 sensor-1

Electrochemical gas sensor series MST141 H2 sensor product description : MST141 electrochemical hydrogen sensor is a fuel cell-type sensor. Hydrogen and oxygen undergo corresponding redox reactions at the working electrode and counter electrode, releasing electric charges to form a current. The magnitude of the generated current is proportional to the hydrogen concentration and follows Faraday's Law. The level of hydrogen concentration can be determined by measuring the magnitude of the current. It exhibits high sensitivity and high selectivity to hydrogen, with an extremely fast response to hydrogen. It also features linear output, a long service life, an environmentally friendly structural design, and a unique anti-leakage structure. It is widely suitable for hydrogen concentration detection in fields such as commercial applications, energy storage power stations, and vehicle-mounted systems.
