High/low sensitivity adjustment and automatic zeroing
Our best refrigerant leak detector suited to find most refrigerant leaks
Easy one button operation
The Testo 316-3 is our best refrigerant leak detector yet, that delivers dependable, rugged performance at a great value. The proven heated diode sensor provides great sensitivity down to 0.15 ounces/year including the new refrigerant blends like R-410A, R-407C, and R134-a, allowing you to find the most refrigerant leaks.
Just turn it on and start getting readings immediately to find the most refrigerant leaks. Thanks to the automatic zeroing, the Testo 316-3 is extremely fast and can be used even in previously contaminated areas, making it our best refrigerant leak detector yet. The 316-3 has an LED indicator, automatic zeroing, and audible alarm, all in a rugged housing.
testo 316-3 leak detector – benefits at a glance
Can detect all common refrigerants: CFCs, HFCs, FCs
Highly sensitive sensor ( < 4 g/a - 1g/a according to DIN EN14624:2012 standard) - can detect even the smallest leaks
Ready for use – there’s no need to select cooling agent characteristics first
Automatic zero setting – can detect leaks in rooms that are already contaminated
Visual and audible alarm which are activated when a leak is detected
The simple design of the testo 316-3 enables the sensor to be changed in just a few seconds and means the sensor is always ready for use.
Tightness testing of refrigeration systems
The testo 316-3 meets all the requirements of the F gases regulation thanks to the high sensitivity of 4 g/a. This means you can find every leakage – no matter whether it involves an R22, R134a, R410a or another refrigerant.
