MPS™ Flammable Gas Sensor
A calibration-free LEL sensor that detects a broad spectrum of combustible gases and mixtures — with immunity to poisoning and saturation and a 15-year sensor life.



World-Class OEMs Trust the MPS™ Sensor






Gases the MPS™ Detects
Combustible Gases
The MPS™ Flammable Gas Sensor detects a broad spectrum of combustible gases and mixtures with one factory calibration.
TrueLEL™ Performance Gases
We provide verified TrueLEL™ performance for a subset of the most common combustible gases. These gases have been fully validated to deliver high-accuracy %LEL measurements across environmental conditions.

How the MPS™ Works
A MEMS-based sensing platform that measures the molecular properties of gases to deliver accurate, stable, multi-gas detection — without required field calibration.
Why Engineers Choose the MPS™
Low-maintenance, highly accurate, and robust.
- 15-year sensor life
Unparalleled 15-year sensor life means low total cost of ownership and ensures uninterrupted monitoring.
- Automated multi-gas detection
Automatically determines and applies the correct sensitivity factor (k-factor) in real time.
- No required field calibration
Unlike catalytic bead sensors, the MPS™ requires no field calibration and is immune to sensor poisoning and saturation — eliminating the prohibitive cost of quarterly calibration trips & sensor replacements.
- 0.1% LEL Resolution
Resolution to 0.1% LEL with built-in environmental compensation for temperature, relative humidity, and pressure for near-zero false positives.
- Low power consumption
As low as 1.35mW, making it ideal for battery-powered portable gas detectors.
- Certified as Intrinsically Safe
Certified for Class I, Division 1 (FM, CSA) and Zone 0 (ATEX, IECEx) and EN 50271 compliance.
- Very wide operating range
-40°C to 75°C operating range with up to 100% relative humidity.
- Self-testing capability
Built-In Self-Test (BIST) capability continuously evaluates the system to ensure it is operating to specification.
