SmartGAS Transmitter EVO Pro

Fast and Reliable Refrigerant Monitoring

The TRANSMITTER EVO Pro from SmartGAS sets the standard for precise, long-term ambient air monitoring of refrigerants using proven dual-beam NDIR technology with a reference channel.

Engineered for leak detection at low concentrations (ppm), this wall-mount transmitter delivers exceptional performance in refrigeration and HVAC environments – detecting up to 20 different gases with a single sensor, including key Freons such as R507, R513a, R1234yf, R1234ze, and more.

Dual selectable ranges (1000 ppm and 2000 ppm) plus easy target gas selection via internal calibration curves give you unmatched flexibility to adapt the device to your exact application without compromise. The dual-beam design ensures high stability, minimal drift, fast response times, and low detection limits, while the robust construction supports simple installation and low-maintenance operation over years of service.

Protect critical systems, prevent costly refrigerant losses, ensure regulatory compliance, and safeguard personnel and equipment with reliable early warnings. The TRANSMITTER EVO Pro combines cutting-edge technology with practical handling, making it the go-to choice for demanding refrigeration monitoring applications where accuracy, longevity, and ease of use matter most.
