Fieldpiece ARH5 In-Duct Psychrometer Head, For Use With HS Series DMMs, Fieldpiece® Datalogger or HV AC Guide® System Analyzer, 0.1 deg F Resolution and -4 to 140 deg F Storage Temperature

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. Your ARH5 measures both 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 data logger or HVAC Guide® System analyzer. For other meters, use Fieldpiece ADLS2 test leads or theAHDL1 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 Super heat calculations. Go wireless with your ARH5 by using Fieldpiece wireless transmitters (ET2W/EH4W) to send measurements over the-air to Fieldpiece wireless receivers (HG3, LT17AW, EH4W ) anywhere on the jobsite.
