Open Path gas detector
- Measured up to a distance of 200 meters
- Continuous operation in extreme and harsh environmental, such as fog, snow, rain, vibration, and solar radiation.
- Heated optics to improve performance in icing, condensation and snow conditions
- High Sensitivity and fast response to Hydrocarbon gases, such as methane, ethylene, propane, ethane, butane
- Simultaneous detection of C1-C8 flammable gases
- Solar blind and immune to industrial environments
