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. When coupled with the P51 TITAN digital manifold, the user has the necessary information for complete system diagnostics. Each device utilizes Low Energy Bluetooth (BLE) technology to interconnect with each other and any smart device: Android and iOS. All YJACK Series devices can also communicate directly with the P51-870 TITAN Series Digital Manifold simultaneously. The YJACK VIEW App provides ease of access to all information measured by the YJACK Series of devices.
