A Little Change Goes a Long Way

With the freedom to work the way you want to

  • 350' Wireless range
  • Precise placement with untethered design
  • All-in-one static, gas and draft pressure
  • Record up to 8 readings at once* in Job Link App

The revolutionary new JL3KM2 Job Link® System Manometer probes give HVACR pros the freedom to work the way they want to -- unrestricted by hoses, so technicians get readings from optimal locations on every system, every time.

Short hose length keeps things neat, and independent sensors allow for direct placement on test ports. Measure between zones without snaking a hose past the door. Dial in gas pressure of a furnace. Optimize total external static pressure of equipment. Pinpoint duct leaks and restrictions. Increase comfort and do more.

Unlike traditional dual port manometers, Fieldpiece's revolutionary untethered design lets contractors place each probe independently in exact locations, to see up to 8 reliable pressure readings at once* -- all fed directly into the Fieldpiece Job Link app for maximum convenience.

Measure and view real-time return static, supply static, and total external static pressure all at once from up to 350' away.  Get single, dual or multiport measurements with the freedom to work the way technician like, from anywhere on the job site. They now have the versatility they've always needed.

*Dual measurements available at launch. Up to 8 measurements available Summer 2020. Individual probes also available, part number JL3MN.
