Intended use
This device is intended for professional residential and commer-
cial use including small firms and commercial operations. The
appropriate specialist knowledge is required to operate the device.
The device may only be used to measure the following gases
(depending on the device model and additional equipment):
●
Methane CH
4
/propane C
3
H
8
/butane C
4
H
10
●
Carbon dioxide CO
2
●
Oxygen O
2
●
Hydrogen sulphide H
2
S
●
Carbon monoxide CO
The device must
not
be used for:
●
Gas analysis of technical processes
●
Monitoring liquids
The device can be used up to a temperature of 40 ºC. However,
high temperatures reduce the lifetime of the sensors and re-
chargeable batteries.
If a device with an electrochemical sensor is exposed to gas
concentrations above the measuring range limit
, this can reduce
the lifetime of the sensor.
