The Honeywell S301-IRF-R134A is a refrigerant gas sensor utilizing infrared (IR) technology. Weighing 2.33 lbs, it is built to deliver accurate readings within a measurement range extending from 0 to 1000 ppm. The voltage rating for this device spans from 8.5 to 12.5 Vdc, making it versatile for various applications. Under maximum load, it supports a current rating of 1 A at 10 Vdc.

This sensor provides a resolution of 1 ppm and features a deadband of 20 ppm. When it comes to precision, it offers accuracy of ±10 ppm at a concentration of 50 ppm and ±40 ppm at 500 ppm.

For operational efficiency, a response time of T90 is established at 60 seconds, while the warm-up phase requires 15 minutes before the sensor can operate at its full potential. The working temperature range is confined between 0°C and 40°C. In terms of humidity tolerance, the S301-IRF-R134A functions optimally in environments with relative humidity levels from 0 to 95%, provided there is no condensation.

Constructed with an enclosure of ABS and polycarbonate materials, this sensor is designed to endure various environmental factors. Calibration is specifically tailored for R134A, enabling precise measurement and monitoring in appropriate refrigerant applications.
