The YJACK Temperature/Humidity Kit includes two YJACK Temperature Clamps, two YJACK DEW Psychrometers, and one YJACK PATH. The YJACK TEMPERATURE CLAMP provides wireless Bluetooth measurements for the surface temperature of pipes up to 1.25" diameter and has a flexible cable connection for easy access in small and difficult-to-reach areas. Using a Bluetooth signal, the YJACK DEW PSYCHROMETER wirelessly measures temperature, humidity, wet bulb, dew point, and more in ambient air or ventilation ducting. The YJACK PATH RANGE EXTENDER connects and re-broadcasts up to six YJACK devices and up to two P51-870 TITAN devices at one time using a Bluetooth signal while providing amplified signal strength through difficult-to-penetrate barriers.

The YJACK Temperature Clamp provides wireless Bluetooth measurements for the surface temperature of pipes up to 1.25" diameter and has a flexible cable connection for easy access in small and difficult-to-reach areas. The YJACK Temperature Clamp is compatible with YJACK VIEW App and P51-870 TITAN devices and has an extended battery life of 1200 hours.

Use the YJACK DEW Psychrometer to easily and wirelessly measure temperature, humidity, wet bulb, dew point, and more in ambient air or ventilation ducting using a Bluetooth signal. The optimized sensor housing is designed for increased air exchange and better response time and with 1500 hours of extended battery life. The YJACK DEW PSYCHROMETER is compatible with YJACK VIEW App and P51-870 TITAN devices.

With 75 hours of continuous-duty battery life, the YJACK PATH Range Extender connects and re-broadcasts up to six YJACK devices and up to two P51-870 TITAN devices at one time using a Bluetooth signal, while providing amplified signal strength through difficult to penetrate barriers. The new YJACK Path Range Extender works seamlessly with all YJACK devices, P51-870 TITAN, and the new YELLOW JACKET YJACK VIEW App.

The PATH amplifies signal strength through difficult to penetrate barriers and adds an additional 400 ft line of sight signal range (Radio interference and nearby obstructions may reduce signal strength).

YJACK for more Connected Techs

The YJACK Series is a network of devices that form a new platform offering a total HVAC/R diagnostics solution. Multiple devices can measure system and environmental parameters, providing a complete picture of a system’s condition. Each device utilizes Low Energy Bluetooth (BLE) technology to interconnect with each other and any smart device, Android or iOS. Many of the YJACK Series devices can also communicate directly with the P51-870 TITAN Digital Manifold simultaneously.

The YELLOW JACKET YJACK VIEW App provides seamless integration with YJACK and P51-870 TITAN devices offering a complete HVAC/R system diagnostic solution. Just use your YJACK and P51-870 TITAN devices with your smartphone for complete system analysis.
