Description
Fieldpiece JL3KH6 Job Link Charge & Air Test Bluetooth Probe Kit
The Fieldpiece JL3KH6 gives HVAC technicians a complete wireless system snapshot — from the condensing unit to the air handler — in a single kit. Live pressure, pipe temperature, and psychrometric readings stream to your phone via the Job Link™ app, so you can diagnose charge and airflow issues without running back and forth between units.
Key Features & Trade Benefits
- Serious wireless range — up to ~300m line-of-sight; typical jobsite range ~100–350 ft around buildings
- Rapid Rail™ pipe clamps (JL3PC) — stabilise in ~3 seconds with ±0.6°C (±1°F) accuracy for tight superheat/subcooling targets
- Pressure probes (JL3PR) — angled 1/4" fitting, accurate at any elevation, A2L-compatible for modern refrigerants
- Flex psychrometers (JL3RH) — fast DB/WB/RH/DP readings for airflow tuning and charge verification
- Job Link™ App logging — capture, graph, and share results from site for handover reports and warranty records
- Rugged, site-ready build — weather and impact-resistant probes in a padded carry case
What’s Included
- 2 × JL3PR Pressure Probes (discharge/suction)
- 2 × JL3PC Rapid Rail™ Pipe Clamp Probes
- 2 × JL3RH Flex Psychrometer Probes
- Quick-access padded carry case
- 12 × AAA batteries (2 per probe)

Compatibility
Works with split systems, ducted, VRF/VRV, and refrigeration circuits across common refrigerants including R32 (A2L), R410A, R22, and R134a. Integrates with the Fieldpiece SM480VINT digital manifold for on-manifold viewing and full Job Link™ logging.
FAQs
Q: Is the Bluetooth range really that long?
A: Fieldpiece lists up to ~300m line-of-sight. Around walls and plant, ~100–350 ft is typical — sufficient to monitor indoor air data from the condenser pad.
Q: Can I use this on R32 systems?
A: Yes — the probes are measurement tools and are A2L-compatible. Always follow Safe Work and AS/NZS procedures when working with A2L refrigerants.
Q: Does it integrate with my Fieldpiece manifold?
A: Yes — pairs with SM380V/SM480V for on-manifold viewing, plus full logging in Job Link™.
