MIPEX-04 [CH4]
SOLUTION FOR PORTABLE AND WIRELESS METHANE DETECTION
MIPEX-04 [CH₄] is an ultra-low power NDIR sensor designed for continuous methane monitoring in portable gas detectors, including gas clip devices and battery-powered wireless analyzers.
Its energy-efficient design enables compact instruments to operate autonomously for over 2 years on a single battery.
Features
High-performance methane (CH₄) sensor for portable detectors, gas clip devices, and battery-powered wireless analyzers.
MIPEX-04 [CH₄] provides accurate and energy-efficient methane detection in explosive environments, with ultra-low power consumption and smart NDIR technology.
-
ULTRA-LOW POWER CONSUMPTION
Lowest available power consumption among combustible gas sensors from 0.04 mW.
-
INTEGRATED MICROCONTROLLER
Delivers linearized, temperature-compensated digital output via UART interface.
-
TECHNOLOGY
Non-dispersive infrared (NDIR) sensing founded on selective absorption of infrared light, utilizing a dual-wavelength LED-based method to minimize the effects of humidity, dust, and optical contamination.
