Frequently Asked Questions

Can this detect R410A leaks?

Yes, it detects all halogenated refrigerants including R410A, R22, R134a, R404A, R32, and R1234yf.

How long does the sensor last?

The heated diode sensor typically lasts 100+ hours of use. Replacement sensor tips are available when sensitivity drops.

Is this better than bubble solution for finding leaks?

Yes — a heated diode detector finds leaks too small for bubble solution to show. It is the industry standard for leak detection and required for EPA compliance in many cases.

Does it work outdoors?

It works best in calm conditions. Wind can disperse refrigerant and cause false readings. For outdoor condensers, shield the area being tested or use on calm days.
