JL3RH is a Flex Psychrometer Probe that measures %RH, dry bulb, wet bulb, dew point, and enthalpy at a register/ grill, in the ductwork, 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 1000' (305 meters) wireless range away. This probe has a long flexible wand with a super strong sliding magnet for easy measurements anywhere on the system.
JL3RH is a Flex Psychrometer Probe that measures %RH, dry bulb, wet bulb, dew point, and enthalpy at a register/ grill, in the ductwork, 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 1000' (305 meters) wireless range away. This probe has a long flexible wand with a super strong sliding magnet for easy measurements anywhere on the 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.
* All JL3RH's can be upgraded through a firmware update to handle extreme duct temps from -40°F to 250°F thru the Job Link App. Simply open the Fieldpiece Job Link App and update the probes.
