S3840R1234YF - R-1234yf, HFO-1234yf Gas Detector 0-5000 PPM, Infrared sensor - SMART3-R LITE

S3840R1234YF SMART3-R LITE refrigerant gas detectors are employed to detect 2,3,3,3-Tetrafluoropropene, HFO-1234yf, R-1234yf compounds (ppm) in non classified areas.

The SMART3-R LITE allow to monitor A1 and A2L refrigerant gasses in machinery rooms and refrigeration plants.
The detectors employ a unique cost-effective IR sensor and provide 2-output relays. A front LED ring offers a visual indication of the detector' status while an internal buzzer activates to warn of any fault or alarm condition.
SMART3-R are rated to IP42 and feature one-man calibration via the STS/CKD+ series calibration keypad.
