SENSITRON S3839R407C Detector for R407C, 1000 and 2000 ppm thresholds, 12-24 Vdc

The SMART3R LITE detector is developed to monitor the concentration of refrigerant gases and carbon dioxide in engine rooms and refrigeration systems. The design is aimed at having a product with an excellent quality/price ratio, thanks also to the use of a special infrared sensor housed in the front ring. The status of the detector is constantly displayed by special LEDs that illuminate the transparent ring and notified by an internal buzzer. The SMART3R LITE detector has a 12-24 Vdc power supply and has two relay outputs; optionally a card for serial communication can be added. The case is made of polycarbonate, with a total size of 130 x 130 x 74 mm; has two outputs with M20 cable glands already mounted. On the sides there are pre-formed guides that can be drilled to add up to 6 M16 cable glands.
