JL3KM2INT - Job Link® System Dual Port Manometer Probe Kit

Our Dual Port Manometer Probe Kit ensures accurate and stable pressure measurements.

- Untethered design provides precise placement;

- 300m wireless range to connect to Job Link® tools;

- All-in-one static, gas, and draft pressure.

The JL3KM2INT gives you the freedom to work from anywhere on site, unrestricted by hoses.


Three reasons why you need our JL3KM2INT Probe Kit

1. Freedom to work

Feeling restricted because of hoses that are not long enough? That’s in the past! The JL3KM2INT Probe Kit gives you the freedom to work the way you want because of its untethered design. You can place each probe independently in the exact location you need so you receive readings from optimal locations on every system, at every job.

2. Wireless and fast

Not only are the problems, they also come connected to the Job Link® system. Receive single, dual, or multiport measurements from anywhere on the job site with the 300m wireless connection to your Job Link® device.

3. All-in-one probes

Measure static, gas, and draft pressure with our JL3KM2INT pressure probes for your maximum convenience. You no longer need different tools to do different pressure measurements: with the Fieldpiece pressure probes, you can do it all at once.
