Contact Sales Rep

The highly advanced MIPEX-14 portable gas sensor has an LED based dual beam and dual wavelength technology. The operating principle of the sensor is based on NDIR technology, that is, on selective absorption of LED produced infrared radiation by gas molecules. It is intended for fixed and portable no-maintenance gas detectors for industrial safety with automatic continuous measurement of the concentration of hydrocarbons and carbon dioxide in the atmosphere of hazardous areas. It has a differential dual beam and dual wavelength method that allows for compensation of aging parts, optical element impurity and other non-selective hindrances, which provides an extremely high stability of operation.

Features:

Target application: fixed and portable no-maintenance gas detectors for industrial safety.
Allows designing battery operated gas detector lasting no less than 12 months without charge.
Average operating current is less than 300 microAmps.
Smart sensor with embedded microcontroller returns linearized, temperature-compensated output data.
LED based dual beam / dual wavelength technology.
Provides intrinsically safe explosion protection level “ia” which does not need metal-ceramic filters.

Measurement range

Detectivity from:

50 ppm for methane (CH₄)
20 ppm for propane (C₃H₈)
