Testo 316-2-EX Multi-purpose Gas Leak Detector

Includes: testo 316-2-EX multi-purpose gas leak detector with explosion protection (ATEX, EU/EFTA), including bag and charger.

Reference 0560 3164

Brand Testo

The testo 316-2-EX is a gas leak detector for the short-term detection of leaks in gas and refrigerant systems in potentially explosive atmospheres of the class ATEX II 2 G Ex ib IIC T1Gb according to Directive 2014/34/EU (ATEX).

Do not allow the sensor to come into contact with moisture or acids, as it will react cross-sensitively.

The following substances can be detected:
Methane CH₄
Propane C₃H₈
Butane C₄H₁₀
Hydrogen H₂Refrigerants (R1234yf, R134A, R404A, R407C, R410A, R1234ze, R290,R417A, R513A, R32, R449A, R22)_.
Methane (main component of natural gas) or hydrogen are lighter than air, detection should be carried out above the pipe / suspected leak.
Testing propane and butane gas lines: Propane and butane are heavier than air, detection should be carried out below the pipe / suspected leak, starting from the bottom and working upwards.

Explosive limits of flammable substances

A flammable substance in the air has a lower explosive limit (LEL) and an upper explosive limit (UEL).
The air/gas mixture is flammable anywhere between these two limits, potentially leading to an explosion (critical range).

Below the LEL, the mixture is too lean for an explosion, and above the UEL it is too rich (non-critical range).

The explosive limits depend on the substance:
Methane CH₄: LEL 4.4 vol.% / UEL 16.5 vol.%
Propane C₃H₈: LEL 1.7 vol.% / UEL 10.9 vol.%
Butane C₄H₁₀: LEL 1.4 vol.% / UEL 9.4 vol.%
Hydrogen H₂: LEL 4.0 vol.% / UEL 77.0 vol.%
Refrigerant: There are flammable and non-flammable refrigerants.R290, for example, is chemically identical to propane and therefore equally flammable.
