SKU
SMART3RL
Monitor A1 and A2L refrigerant gases with the Sensitron Smart3-R Lite Fixed Gas Detector. Suitable for use in refrigeration plants and machinery rooms, the Smart3-R Lite employs the use of an infrared sensor to accurately detect R134a, R32, carbon dioxide and other toxic and flammable refrigerant gases that can be harmful to workers and contribute to ozone depletion. The Smart3-R Lite is rated IP54, with protection against dust and water splashing.
The Sensitron Smart3-R Lite features:
- Pre-set output relays
- Optional RS485 communication with an STS/IDI card
- Multicolour LED ring
- Standard measurement ranges 0-20% LFL and 0-5000 ppm
- Audible warnings with an internal buzzer
- Ongoing self-diagnosis
- Standard power supply of 12-24 Vdc
- IP54 rating
- Compliance with ISO 5149.3 standards
