Extech RD350 Refrigerant Leak Detector with Audible and Visual Alerts

What is the Extech RD350 Refrigerant Leak Detector?

The Extech RD350 Refrigerant Leak Detector is a professional handheld tool designed for HVAC and refrigeration technicians who need fast, reliable detection of refrigerant leaks during installation, maintenance and fault-finding. Using a heated diode sensor, it detects all commonly used refrigerant gases including R22, R32, R134a, R404A, R407C, R410A and HFO-1234yf, with a high sensitivity down to 3 g per year.

A tri-colour LED leak indicator, variable audible alarm and 400 mm flexible probe make it easy to pinpoint leaks around compressors, pipe joints and confined spaces. The RD350 is well suited to commercial and industrial HVAC systems where accuracy and speed matter on site.

 

How does the RD350 perform in everyday HVAC work?

The RD350 offers three selectable sensitivity levels to suit different environments, with ambient concentration reset to improve accuracy in high background conditions. Quick warm-up and simple controls allow engineers to work efficiently during routine servicing and emergency call-outs.
