Do not allow the sensor to come into contact with moisture or acids, as it will
react cross-sensitively.
4 Intended use
The testo 316-1-EX is a gas leak detector for the short-term detection of leaks in
gas systems in potentially explosive atmospheres of the class
ATEX II 2 G Ex ib IIC T1G according to Directive 2014/34/EU (ATEX).
The following substances can be detected:

Methane CH
4

Propane C
3
H
8

Butane C
4
H
10

Hydrogen H
2
The instrument is not suitable for precise measurement of the gas
concentration.
ATTENTION
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 CH
4
: LEL 4.4 vol.% / UEL 16.5 vol.%
-
Propane C
3
H
8
: LEL 1.7 vol.% / UEL 10.9 vol.%
-
Butane C
4
H
10
: LEL 1.4 vol.% / UEL 9.4 vol.%
-
Hydrogen H
2
: LEL 4.0 vol.% / UEL 77.0 vol.%
ATTENTION
Restrictions on the field of use
-
Do not use the instrument as a monitoring instrument for personal
safety! The instrument is not protective equipment!
-
Do not use the instrument as a gas analyzer! The sensor detects
almost all combustible gases alike.
