Installation
3.2.2 Install the purge filter
The purge filter (refer to Figure 3 on page 9 , item 3) is used for maintenance (purge and
zero count) of the MET ONE 237 particle counter. The purge filter permits direct sampling
of pressurized air at pressures ranging from 30 to 150 psi.
Note: It is recommended that the purge filter be applied to the counter before moving the MET ONE
237 particle counter to avoid cross contamination.
Note: Verify the zero counts before moving the MET ONE 237 particle counter.
To install the purge filter:
1. Remove the red sensor inlet cap or the isokinetic probe from the MET ONE 237
particle counter.
2. Connect the purge filter to the sensor inlet.
