Yellow Jacket 67063 Yjack Dew Wireless Psychrometer

Product Description

The YELLOW JACKET 67063 YJACK DEW Psychrometer is a wireless Bluetooth instrument designed for HVAC/R technicians who need fast, accurate psychrometric measurements in the field. It measures percent relative humidity, dry bulb temperature, wet bulb temperature, dew point temperature, and enthalpy change across evaporator coils — giving techs a clear picture of system operational efficiency without running separate instruments. The 67063 uses Bluetooth 4.2 low-energy radio with a 400-foot line-of-sight signal range and delivers a rated 1500-hour battery life on two included AAA batteries. It is IP52 rated for dust and drip resistance and carries a 2-year warranty.

The 67063 is built for residential and commercial HVAC/R service work. Its 8-inch flexible steel wand lets technicians position the sensor precisely inside ventilation ducting without awkward tool handling. The optimized sensor housing promotes increased air exchange for faster, more reliable response. It pairs wirelessly with the YJACK VIEW App and P51-870 TITAN devices running firmware version v2.0 or later, fitting naturally into a YJACK Series diagnostic workflow. Typical applications include evaporator coil performance checks, duct traverses, and indoor air quality assessments.

Installation Notes

The 67063 is a field measurement instrument installed and operated by licensed HVAC/R technicians. Before inserting the wand into an active duct system, confirm the air handler or fan is in a safe operating state and that duct penetration is permitted at the chosen location. Secure the unit to sheet metal or duct surfaces using the built-in mounting magnet and verify Bluetooth pairing with the YJACK VIEW App or TITAN device before recording measurements. Follow all applicable mechanical and safety codes for duct access and instrumentation use.
