Fieldpiece JL3KM2 Job Link Dual Port Manometer Probe Kit

SKU CH-NWDN-B2HMQ

A dual-port manometer probe kit for real-time gas-pressure measurement and pressure-drop analysis via the Job Link System app

  • TypeMultifunction Testers
  • Reliable pressure readings from any job site location
  • Measure real-time pressure drops across systems
  • Find inlet and outlet gas pressures accurately
  • Switchable P1-P2 indicator simplifies differential readings
  • Job Link System app compatibility enables remote monitoring

Dual-Port Manometer Probe Kit

The Fieldpiece JL3KM2 is a dual-port manometer probe kit built for HVACR technicians who need reliable pressure readings on site. It connects to the Job Link System app so measurements can be viewed and logged on a mobile device while you work.

Suited for live system diagnostics

This kit suits contractors who measure real-time pressure drops, verify inlet and outlet gas pressures and need a quick zero-to-atmosphere function. It is not for users who require built-in data logging without a smartphone or who need a permanently mounted gauge panel.

Job Link System app compatibility

The Job Link System app turns a phone or tablet into the display, letting you switch between P1 and P2 indicators and store readings digitally. No separate handheld display is included, so a compatible mobile device is required to use the probes.

Highlights

  • Reliable pressure readings from any job site location
  • Measure real-time pressure drops across systems
  • Find inlet and outlet gas pressures accurately
  • Switchable P1-P2 indicator simplifies differential readings
  • Job Link System app compatibility enables remote monitoring

Questions about this item

What mobile device and app are required to view readings from the JL3KM2 probes?

The Job Link System App on a compatible smartphone or tablet is needed to display real-time pressure measurements from the dual-port manometer probes.

Can the JL3KM2 probes measure gas pressure on equipment that uses older mechanical gauges?

Yes, the probes find inlet and outlet gas pressures digitally, letting you compare readings directly against legacy mechanical gauges on the same system.

How do I confirm the JL3KM2 is measuring pressure correctly after connecting it?

Use the easy zero-to-atmosphere function on the Job Link System App to zero the sensors, then verify the switchable P1-P2 indicator shows expected differential pressure.
