Fieldpiece JL3RH Flex Psychrometer Probe Job Link System

The Fieldpiece JL3RH is a Flex Psychrometer Probe that measures %RH, dry bulb, wet bulb, dew point, and enthalpy at a register/ grill, in the duct work, or just walking around. This Psychrometer Probe is part of Fieldpiece’s Job Link System that allows you to directly send air measurements to the Job Link app on your mobile device up to 350’ away.

The Fieldpiece Psychrometer JL3RH probe has a long flexible wand with a super strong sliding magnet for easy measurements anywhere on the system. A service technician can get instant live readings from ducts, plenums, registers, or grilles for accurate diagnostics of a system.

The magnet will also hold the JL3RH flexible wand in place when measuring temperature in a duct. Drill a 3/8” hole in the duct, bend the flexible wand, and slide into the predrilled hole.

The Fieldpiece JL3RH Flex Psychrometer Probe can connect directly to both the Job Link app and the wireless SMAN SM380V (3-port) or SM480V (4-port) manifolds to see live air temperature readings while you are making adjustments to the system. In addition, you can use the Job Link System app to program the JL3RH to log measurements starting at a specific time of day for up to 7 days.

The probe have a switchable return/ supply indicator (red for return/ blue for supply) which automatically tells the Job Link System app which side you have selected for each probe.

Multiple psychrometers can be used for system wide testing in real time.

The water resistant, rubberized, protective housing on the Fieldpiece JL3RH is both comfortable to handle and durable. The probe will automatically power off after 2 hours which can be disabled if desired.
