Fieldpiece JL3KH6 Job Link Charge & Air Test Bluetooth Probe Kit

Fieldpiece JL3KH6 Job Link Charge & Air Test Bluetooth Probe Kit

The Fieldpiece JL3KH6 is a comprehensive wireless diagnostic kit for HVAC/R technicians who need to capture a full system snapshot — refrigerant charge, airflow, temperature, and humidity — simultaneously and wirelessly. The kit combines pressure probes, pipe clamp temperature probes, and psychrometer probes, all connecting to the Fieldpiece Job Link app via Bluetooth for real-time data logging, system diagnostics, and report generation.

At $1,459.99, the JL3KH6 is a professional investment suited to technicians who regularly perform commissioning, service diagnostics, and system performance verification on residential and commercial HVAC/R systems. The wireless design eliminates the need to run cables between the unit and the technician, reducing setup time and improving safety on the job.

Confirm exact probe inclusions, compatible Job Link app version, Bluetooth range in your specific environment, and all specifications against the Fieldpiece manufacturer's current datasheet before ordering.

Frequently Asked Questions

What probes are included in the JL3KH6 kit?

The JL3KH6 includes high-side and low-side pressure probes (JL3PR), pipe clamp temperature probes (JL3PC), and psychrometer probes (JL3RH). Confirm exact quantities of each probe against the Fieldpiece datasheet before ordering.

Does the JL3KH6 work with the Fieldpiece Job Link app?

Yes — all JL3 series probes connect to the Fieldpiece Job Link app via Bluetooth. The app is available for iOS and Android. Confirm current app compatibility with your device and OS version before ordering.

What is the Bluetooth range?

The probes have a stated wireless range of 100+ metres. Actual range varies depending on obstructions, building materials, and interference. Confirm suitability for your specific jobsite environment.

Can I buy individual probes separately?

Yes — the JL3PC, JL3PR, and JL3RH probes are available individually. See the Fieldpiece Job Link range or contact our team for individual probe pricing.

What refrigerants is the pressure probe compatible with?

The JL3PR pressure probe measures pressure — refrigerant compatibility depends on your manifold and system fittings. Confirm compatibility with your specific refrigerant and system before use. Refrigerant handling requires appropriate trade qualifications.

What is the warranty?

Confirm current warranty terms with HVAC Trade Supply at time of purchase. Fieldpiece tools are generally supported by a manufacturer warranty — refer to product documentation for full details.
