MPS Refrigerant Gas Sensor
The Nevada Nano MPS Refrigerant Gas Sensor accurately and reliably detects R-32, R-454b, R-1234yf, R-744, R-290, R-600 and many other refrigerant gases used in commercial and residential HVAC applications.
The secret to the sensors long life and low maintenance is MPS™ - Molecular Property Spectrometer technology. A MEMS transducer is mounted onto a PCB and open to ambient air. The presence of a flammable refrigerant gas causes changes in the thermodynamic properties of the air/gas mixture that are measured by the transducer, then processed by patent-pending algorithms to report accurate gas concentrations.
The MPS Refrigerant Gas Sensor has been configured to provide a robust, refrigerant-dedicated sensing solution like that can reliably recognize leaks over a long field life, in harsh, real-world environments with no servicing required.

Sensor Evaluation Kit
The Molecular Property Spectrometer™ Flammable Gas Sensor Evaluation Unit is a user friendly system developed for assessing flammable gas detection performance. The sensor connects to a provided PCB for communication with a PC (USB) or breakout to individual sensor signals (optional 5-wire harness). A quarter-turn plastic gas mask and housing is included to provide a sealed headspace above the sensor using a tube cap inlet and outlet.
