The YELLOW JACKET 67073 is the YJACK Charging Air Kit, a complete diagnostic tool set designed for HVAC system charge and airflow analysis. The kit combines wireless pressure and temperature probes with DEW probes to deliver real-time system charge readings and psychrometric calculations in a single workflow. All readings are viewed, logged, and reported simultaneously through the YJACK VIEW app. This kit is intended for use by licensed HVAC technicians performing system commissioning, charge verification, or efficiency diagnostics on residential and light commercial cooling and heating equipment.
The 67073 is suited for HVAC service calls where both refrigerant charge verification and supply and return air analysis are required in one setup. Technicians connect the wireless pressure and temperature probes to the refrigerant circuit for instant charge data, then position the YJACK DEW probes at the supply and return air ducts to calculate cooling and heating efficiency through psychrometric analysis. The YJACK VIEW app aggregates all probe data simultaneously, reducing the need for multiple separate instruments on the job.
Designed for use with the YJACK system of wireless probes and the YJACK VIEW app for HVAC system diagnostics on residential and light commercial cooling and heating equipment.
This kit is intended for installation and use by licensed HVAC technicians familiar with refrigerant handling and airside diagnostics. Before connecting pressure probes to the refrigerant circuit, isolate the system as required by local codes and follow all applicable EPA Section 608 refrigerant handling regulations. Ensure the YJACK VIEW app is installed and updated on a compatible device before beginning diagnostics. Do not connect probes to energized high-voltage components without following proper lockout and safety procedures.
