Fieldpiece JL3KR4 Wireless Probe Kit

JL3KR4 — a wireless probe kit for system charge verification and rapid HVAC/R diagnostics with the Job Link® app.

Applications

• Charge verification and quick parameter monitoring during HVAC/R service
• Simultaneous pressure and pipe temperature measurement without long service hoses
• Work on critically charged systems and A2L refrigerant installations

Key features

• Wireless range up to 305 m — read results directly in the Job Link® app from a distance.
• 2 × JL3PR pressure probes + 2 × JL3PC pipe clamps — the kit is ready for pressure and pipe temperature checks straight out of the case.
• Automatic pressure calibration — pressure probes maintain reliable readings even when the working altitude changes.
• Rapid Rail® and ~3 s stabilisation time — pipe clamps deliver a stable temperature reading quickly on conductive pipes.
