The JL3RHINT Flex Psychrometer Probe is a state-of-the-art wireless instrument for measuring temperature and relative humidity in HVACR systems. With a 300-metre wireless range and a 9 mm flexible probe, it measures dry bulb, wet bulb, %RH, dew point and enthalpy — all readable directly from the Job Link® app or digital manifold.
Key features
- 300 m wireless range (line of sight)
- On-board data logging: all measurements are automatically recorded and sent to the Job Link® device
- Supply/return switching function to ensure measurements are logged in the right position
- Flexible probe: 9 mm diameter, 235 mm length
- Measures: dry bulb, wet bulb, %RH, dew point, enthalpy
- IP54 protection rating
- Low battery indication via flashing red LED
