Cleaning PID Sensor
Impactor Care
The impactor will require periodic greasing and cleaning which is dependent on the density of air particulates floating in the intended measurement environment.
NOTE : The impactor must be greased before your first measurement.
Greasing and cleaning impactors explained below:
