5.2.1 Installing sensors
Requirements on
the environment
The following must be observed when installing the sensors:
• A site for the sensor must be selected to enable the sensor to
come into contact with the air gas mixture it is to monitor.
• Install the sensor approx. 35 cm above ground level.
Please note
Gases such as chlorine (Cl
2
), chlorine dioxide (ClO
2
) and ozone
(O
3
) are heavier than air and therefore concentrate near the floor.
Please consult the sensor's operating manual if dealing with other
gases.
• Do not install the sensor right beside a heat source (e. g.
radiator, ventilator, etc.).
• Pay attention to the ambient conditions. The temperature,
humidity, etc. must remain constant.
Please note
Avoid sudden changes in temperature (< 5 C/h).
