Description

Extech RD350 Refrigerant Leak Detector

The Extech RD350 Refrigerant Leak Detector delivers fast, accurate detection of refrigerant leaks in HVAC systems, making it a trusty tool for HVAC and refrigeration technicians. It features a highly sensitive heated semiconductor sensor that reliably detects commonly used refrigerant gases, including CFCs, HCFCs, HFCs, and newer blends such as R410A, R32, R134a, R404A, and HFO-1234yf. With a detection sensitivity of just 3 g/year, the RD350 ensures even the smallest leaks are identified before they become costly issues.

The RD350 accommodates different working environments by offering three adjustable sensitivity levels. A tri-coloured LED leak level indicator and variable audible alarm provide clear, immediate feedback, while the 400 mm flexible gooseneck probe allows easy access to hard-to-reach areas, making it easy to pinpoint leaks.

Included with the RD350 is a reference leak for performance verification, along with a durable hard carrying case for safe storage and transport. With a quick 45-second warm-up time and CE certification, it is powered by four AA (1.5V) batteries and is backed by a 2-year warranty.
