Descripción
The ExplorIR®-M-20 (formerly known as MinIR-GC-0026) is a miniature CO2 sensor, capable of measuring up to 20% CO2 concentration by volume. Its compact and robust design enables easy integration into gas monitoring and detection systems.
ExplorIR®-M is specifically designed for applications that require the sensor to operate reliably in extreme environmental conditions, especially where the pressure, temperature or vibration regime is particularly harsh. This makes it the ideal for applications from aerospace to food storage during transportation.
The sensor is designed to take 2 readings per second, making it ideal for applications where gas concentrations are rapidly changing.
The ExplorIR®-M uses patented solid-state optical technology, which enables the sensor to provide high accuracy CO2 measurement capability over an extended lifetime.
Features
- Measures up to 20% CO2
- Low power CO2 sensor

CM-40530 - EXPLORIR-M 20% CO2 Sensor w/ MX Board
- CM-40531 - EXPLORIR-M 20% CO2 Sensor Development Kit - Easy to use, simply plug the sensor module PCB into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide in real time or for data logging. Use a tube cap adapter to create a sampling sensor.
- Sensor Development Kit (CM-200) - Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order sensors on this page, then order the Devkit here.
We recommend that all first-time users purchase either the CM-40531 or CM-200 Development Kit for fastest and easiest results.

Accessories
Gas Sensor Development Kit (CM-200)- designed to provide customers with an easy drop-in solution. Includes our free Gaslab data logging software. Sensor sold separately.
Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently.
Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
Nafion Tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.
Micro Gas Sampling Pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
Probe Enclosure for Development Kits gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.
