SMART 3-R

Overview

The SMART 3-R and 3-R Lite are refrigerant gas detectors designed for use in non-classified areas, machinery/plant rooms and laboratories.

Audible and visual status notifications

The multi-colour LED light ring offers a constant visual indication of detector status whilst an internal buzzer will activate to warn of any fault or alarm condition.

Wide variety of gas and sensor options

Both the SMART 3-R and 3-R Lite have options for the detection of more than ten refrigerant gases, with the SMART 3-R also capable of detecting over ten flammable and toxic gases.

Refrigeration Standards compliance

The devices are compliant with the refrigeration standards EN 378-3; EN 14624; EN 50676; IEC 60335-2-40 Annex LL and ISO 5149-3
