Fieldpiece JL3KH6 Job Link® Wireless HVAC/R Probe Kit

Fieldpiece JL3KH6 — a professional wireless HVAC/R diagnostic kit compatible with the Job Link® system. Comprising six advanced probes (two pressure probes, two pipe clamp temperature probes, and two psychrometer probes), it enables installers and service technicians to perform a complete system heat balance, pressure readings, and refrigerant line temperature measurements from up to 300 metres away.

Applications

• Fast commissioning and diagnostics of air conditioning systems, heat pumps, and refrigeration systems (including compatibility with A2L refrigerants).
• Precise real-time superheat and subcooling measurements directly in the Job Link® System mobile app.
• Comprehensive supply and return air parameter measurement (dry-bulb and wet-bulb temperature, dew point, relative humidity) to assess ventilation and air conditioning efficiency.
• Monitoring and documenting system operating parameters without deploying unwieldy cables or conventional heavy manifolds.

Key features

• Wireless range up to 300 m (1,000 ft) — strong, stable Bluetooth Low Energy (BLE) signal allows simultaneous monitoring of indoor and outdoor units directly on a smartphone or tablet screen.
• JL3PR pressure probes with 45° fitting — exceptionally compact design fits easily into tight service ports. Automatically self-calibrates to atmospheric pressure at any altitude.
• JL3PC pipe clamp probes with Rapid Rail® technology — patented thermocouple uses the copper pipe wall as part of the measurement circuit. Stabilizes in just 3 seconds, unaffected by ambient temperature or wind, for pipes 1/4" to 1 3/8" OD.
• JL3RH psychrometer probes with flexible tip — the long, flexible 9 mm tip and strong sliding magnet allow precise placement in ductwork, plenums, or at supply grilles.
• Direct Job Link® app integration — enables real-time automatic calculations, professional service report generation for customers, and data integration with other Fieldpiece instruments (e.g. clamp meters or combustion analyzers).
• IP54-rated housing — all probes are splash- and dust-resistant for long service life in harsh job-site or rooftop conditions.
