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™ Refrigerant Gas Sensor Evaluation Kits are a user friendly system developed for assessing refrigerant gas detection performance. The sensor (not included) connects to the 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.

Evaluation Kits - Sensor Not Included
  • Mini Sensor Part no. MSP999-MN0000-99
  • S4 Sensor Part no. MSP999-S40000-99

S4 Sensor Mounting Pins

We do NOT recommend soldering wires directly to the pins of the MPS S4 Gas Sensors. We recommend using individual receptacle sockets with wires soldered to the sockets and then plugging the sockets onto the pins of the sensor. Compatible receptacle sockets readily available from numerous distributors are:

  • Mill-Max 9401-0-15-15-23-27-10-0 (This socket has a closed bottom).
  • Mill-Max 0384-0-67-80-23-27-10-0 (This socket has an open bottom).
