Ideal for Machine Rooms and Light Industry:
Designed for machine rooms, laboratories and unclassified areas, the SMART3-R detector provides detection of explosive, toxic and refrigerant gases in safe (unclassified) areas.
With a 4-20 mA output, an RS485 communication bus and a 3-relay board, the circular LED indicator on the front displays the status of the instrument and an internal buzzer is activated in the event of a fault and/or alarm.
The instrument is controlled and calibrated via a keypad with STS/CKD+ display, with a protection rating of IP42. On request, the SMART3-R can be supplied in a version with an additional remote head and a 5m 6-pole cable included.
