Quick Start
1. Connect ARH5 to Fieldpiece meter.
2. Select mVDC range on meter.
3. Remove vinyl slip cover from the
probe tip.
4. Select desired switch position on
ARH5 for temperature, wet bulb,
dew point, or %RH.
5. Read your measurement directly on
the display of the Fieldpiece meter.

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.
Yo u r A R H 5 m e a s u re s b o t h
relative humidity and ambient
air temperature. It also calculates
dew point and wet bulb temperatures
automatically.
The ARH5 snaps directly onto
Fieldpiece HS series DMMs, Fieldpiece
Datalogger or HVAC Guide® System
Analyzer. For other meters, use
Fieldpiece ADLS2 test leads or the
AHDL1 handle adapter.
Use your ARH5 in combination with
the HVAC Guide and easily perform
Target Evaporator Exit Temperature
tests and get more reliable and
convenient Target Superheat
calculations.
