3.3 Remote Access Probe
A remote access probe is available as an optional accessory for
the MiniRAE Plus Professional PID Unit. This probe is
constructed with an aluminum telescoping pointer and 6.5 ft.
Teflon tubing. The telescoping pointer allows the probe unit to
be stored in a compact space when not in use and conveniently
extended into a 4 ft. long pointer to reach difficult to reach
sampling space, e.g. above a ceiling or inside a large container,
etc. The other end of the Teflon tubing can be inserted directly
into the gas inlet tube of the PID unit.
Note: when the remote probe is used, there will be an
additional delay of about 2-3 seconds of the instrument
response because the sample gas has to travel through the 8 ft
tubing before it reaches the sensor module inside the unit. The
traveling speed of air sample inside the tubing is 3 ft per second.
The sampling pump can pull in sample gas from as far as 200 ft
horizontally or 100 ft vertically.
