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.
