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.
