measureQuick compatibility: The probe families shown are listed in the measureQuick compatible-tool catalog.
* Range: Manufacturer-stated maximums. Walls, equipment and the receiving device affect actual range.
1. Screens & manifolds: JB screens show individual readings; use the app for combined superheat / subcooling. NAVAC NSP1 displays saturation temperature after selecting refrigerant in the app. Manifold connections apply to the models listed and may require current firmware.
2. UEi: This row covers the WPP1 / WPC1 / WHP1 configuration described in our HUB6 listing. WPC1 clamps plug into the pressure probes. Newer HUB6 configurations use wireless WPC2 clamps.
3. Yellow Jacket: 1,000 ft applies to clamps from serial YJTC-2433-0001 and DEW probes from YJRH-2439-0001. Earlier versions are rated 400 ft.
4. Fit & charging: Charging connections let a hose connect while the pressure probe stays installed. Single-port probes need an external tee or suitable fitting. Fieldpiece JL3PC requires conductive pipe and clean contact.
