Sensitron Smart3-R Gas Detector
Detects flammable, toxic and refrigerant gases in non-hazardous environments.
Designed for detecting flammable, toxic and refrigerant gases, the Sensitron Smart3-R Gas Detector is a fixed gas detector available with catalytic, infrared or electrochemical sensors. Suitable for gas detection in machinery rooms, residential, and industrial environments, the Smart3-R features:
- Standard 4-20 mA, RS485 and 3-relay outputs
- Multicoloured LED ring
- Audible warnings with an internal buzzer
- Ongoing system self-diagnosis
- Detection of a range of gases with various sensors
- Optional remote sensor head
- Easy replacement of sensors
- Standard 12-24 Vdc power supply. On request 90-240 Vac, without 4-20 mA transmission
- IP42 rating for protection against dripping water and objects more than 1 mm in size
- Complies with the ISO 5149-3 standard
The Smart3-R detector is equipped with multicolour LED lights as an optical indicator of the detector’s status, and an internal buzzer that will alert if any alarm conditions are met.
The Sensitron Smart3-R Gas Detector is available for sale and servicing at Air-Met Scientific. For more information, contact your local Air-Met Scientific office.
