Description

With your purchase of the ARH5 you
now have the ability to take supply/
return temperature, %RH, wet bulb
and dew point measurements from
inside the duct or plenum.
Use the telescopic probe to take
measurements in hard to reach places.

dew point and wet bulb temperatures
automatically.
The ARH5 snaps directly onto
Fieldpiece HS series DMMs, Fieldpiece
C-Tick (N22675) Datalogger or HVAC Guide® System
Analyzer. For other meters, use
CE Fieldpiece ADLS2 test leads or the
AHDL1 handle adapter.
