Using the Bar Hole Probe
To use the Bar Hole Probe (102278-1; 20 in.) attach the probe to the DP-IR Filter cap using the
Quick Connector on the end of the Bar Hole Probe hose.
The Bar Hole Probe has two filters, the Hydrophobic Filter (102277-0) and the Particulate Filter
(102276-0), located in the Bar Hole Probe handle. Unscrew probe handle and ensure that both
filters are clean and dry. Replace if necessary.
Put the Bar Hole Probe handle back together, making sure handle is screwed tightly together and
O-ring makes a tight seal so no leaks will occur during survey. Also ensure that the sampling
holes at the end of the Bar Hole Probe are not blocked or plugged. The probe is now ready for
use.
Note: To ensure the Bar Hole Probe is sealed and assembled correctly, turn on the
instrument and block the holes at the end of the probe. The instrument should flow fault.
When conducting a Bar Hole survey, carefully watch the clear Bar Hole Probe during each
sample to ensure water is not being drawn up into the instrument. For more accurate sample
readings, regularly check the probe filters after survey samples to ensure the filters are clean and
dry.
