HVAC techs, this tool is a game-changer!

The Yellow Jacket YJACK DEW Psychrometer lets you wirelessly measure key psychrometric parameters right from your smartphone.

It uses Bluetooth to connect to the free YJACK VIEW app (or a compatible Yellow Jacket manifold like the P51-870 TITAN).

What does it measure?
Percent relative humidity, dry bulb temperature, wet bulb temperature, and dew point temperature.
It's designed to help you check system efficiency by measuring enthalpy change across an evaporator coil.

The sensor housing is optimized for fast air exchange and quick response time.
It comes with an 8-inch flexible steel wand so you can easily position the sensor inside ventilation ducting or other tight spaces.

The battery life is impressive at up to 1500 hours.
This is part of Yellow Jacket's connected YJACK series, allowing you to build a full diagnostic system.

Ditch the old-school tools and go wireless for faster, smarter HVAC troubleshooting!
