Fieldpiece JL3KM2 Job Link® Wireless Manometer Probe Kit

Fieldpiece JL3KM2 — a professional wireless two-probe manometer kit compatible with the Job Link® system. It allows fast, accurate, and highly convenient static pressure, gas pressure, and draft measurements on HVAC/R systems without the hassle of long sensing tubes running back to a display instrument.

Applications

• Supply and return static pressure measurement in ventilation and air conditioning ductwork
• Total external static pressure (ESP) monitoring on heating and cooling systems
• Gas pressure measurement at inlet and outlet (e.g. setting gas valves on boilers)
• Flue/chimney draft diagnostics and locating airflow restrictions and blockages
• Wireless monitoring, documentation, and report generation directly in the Job Link® mobile app

Key features

• Job Link® wireless system — up to 305 m (1,000 ft) radio range without line-of-sight, for easy parameter monitoring on a phone or tablet.
• Manometer workflow — optimized for precise low static pressure, gas pressure, and draft measurements; cannot be confused with refrigerant manifold probes.
• Strong magnet and ergonomic shape — enables stable attachment to metal HVAC/R equipment enclosures near measurement points.
• Short, precise sensing tubes — prevent tangling and keep the workspace tidy.
• Multiple unit support — quickly select the preferred pressure unit (inWC, mmWC, mbar, psi, Pa) directly in the app.
