MIPEX-01D [C3H8 & CO2]

ULTRA-LOW POWER DUAL NDIR GAS SENSOR
MIPEX-01D [C₃H₈ & CO₂] is an ultra-low power NDIR gas sensor intended for automatic continuous simultaneous measurement of the concentrations of propane & carbon dioxide in the atmosphere of hazardous areas. The sensor can be recalibrated for other hydrocarbons.
Features
MIPEX-01D [C₃H₈ & CO₂] is a dual gas sensor built on energy-efficient NDIR technology. Its low power consumption enables long-term autonomous operation in battery-powered devices, while compact dimensions and ability to simultaneously measure the concentrations of two gases allows to significantly reduce the size of the final device. It is designed for integration into compact portable gas detectors and wireless gas analyzers where space and battery life are critical constraints.
