PID Target Gases
Photoionization detector (PID) sensors can be used to detect a large range of volatile organic compounds (VOCs). The PID sensor’s target gas refers to whatever gas your device is currently attempting to detect. EXO’s readings are adjusted based on the gas it is currently configured to detect.
Although PID sensors target a specific VOC, readings can still be affected by the presence of non-targeted gases. Consult your safety supervisor or industrial hygienist when preparing to use a PID sensor.
EXO’s PID sensor’s target gas is set from the configuration profile in Blackline Live. Under the Photoionization detector section of the Gas sensor settings card, you can choose an existing target gas or set a custom target gas.
You can see the target gas EXO is configured to use in two places:
On start-up
In the Gas options menu:
In both places, EXO’s screen displays the name of the target gas as well as its correction factor.
