Fieldpiece JL3PR Wireless Pressure Probe (Job Link System)

JL3PR — wireless pressure probe for the Job Link system for HVAC/R measurements, with a 45° angled 1/4" fitting, wireless range up to 305 m, and direct port connection that minimises refrigerant loss.

Applications

• suction-side or liquid-line pressure measurement during air conditioning, refrigeration, and heat pump service
• working at service ports in tight or hard-to-access locations thanks to the 45° angled fitting
• diagnostics of critically charged systems and A2L refrigerant installations without long service hoses

Key Features

• Job Link wireless range up to 305 m — sends live readings directly to the mobile app without a separate hub.
• 45° angled 1/4" female flare fitting — simplifies connection to service ports in confined spaces.
• Automatic barometric compensation — readings remain accurate regardless of altitude.
• Direct port connection — minimises refrigerant loss; no hoses needed for readings.
• Suction/liquid-line selector — the app recognises whether the probe is on the low (blue) or high (red) side.
