Dostmann Electronic GD 380 Refrigerant Gas Leak Detector 5040-0380

The GD 380 stands out with its heated diode sensor, delivering rapid and precise detection of all common CFC, HCFC, and HFC refrigerants. Unlike conventional leak detectors, it offers three selectable sensitivity levels and an automatic zero adjustment, ensuring reliable pinpointing of even the smallest leaks.

Highlights

• Detects all CFC, HCFC, HFC refrigerants including R134a, R404a, R407c, R410a, R22
• High sensitivity: <3 g/year (R134a) with response time under 1 second
• 7-level LED bar graph and variable frequency acoustic alarm
• Flexible 35 cm gooseneck probe for hard-to-reach areas
• Peak hold, low battery indicator, and auto power off

In daily use

With a warm-up time of approximately 60 seconds and automatic zero adjustment, the GD 380 is ready when you are. The visual and audible alarms intensify as you approach the leak source, making it easy to trace even in noisy environments. Powered by four AA batteries, it provides up to 40 hours of continuous operation, and the included hard carrying case keeps it protected on the go.
