Fieldpiece JL3PR Job Link Bluetooth Wireless Pressure Probe | HVAC

Fieldpiece JL3PR Job Link Bluetooth Wireless Pressure Probe

The Fieldpiece JL3PR is a wireless pressure probe for the Fieldpiece Job Link system, designed for HVAC/R technicians who need to monitor high-side and low-side refrigerant pressures remotely via the Job Link app. With a compact body that fits into tight spaces, a 1/4" NPT female flare connector at 45°, and a pressure range of 0 to 580 psig, the JL3PR is suited to residential and commercial AC and refrigeration charging and diagnostic work.

Used in pairs — one on the discharge (high) side and one on the suction (low) side — the JL3PR gives you real-time pressure data on your smartphone without standing at the unit or running gauge hoses to a manifold. It connects to the Job Link app via Bluetooth at 100+ metre range.

Frequently Asked Questions

What refrigerants is the JL3PR compatible with?

The JL3PR measures pressure — refrigerant compatibility depends on your system fittings and service ports. Confirm the 1/4" NPT female flare connector is compatible with your system before ordering. Refrigerant handling requires appropriate trade qualifications.

What is the maximum pressure the JL3PR can handle?

The working range is 0 to 580 psig (4,000 kPa). The maximum overload rating is 800 psig (5,500 kPa). Do not exceed the overload rating.

Do I need two probes for a full system reading?

Yes — for simultaneous high-side and low-side pressure monitoring, you need two JL3PR probes. Both the JL3KR4 and JL3KH6 kits include two pressure probes.

What is the warranty?

Confirm current warranty terms with HVAC Trade Supply at time of purchase.
