Real-world use and benefits

Designed for on-site service, this digital manifold helps technicians diagnose pressure imbalances, verify leaks, and monitor charging steps without guesswork. The three-hose setup with shut-off valves enables safer, faster measurements as you connect to different points in the system. Visual and data feedback supports informed decisions during a service call, whether you’re topping off refrigerant, evacuating a system, or confirming a stable reading after a repair.

• Observe charging status clearly on the display to guide your next steps
• Capture and compare pressure trends across multiple refrigerants with confidence
• Use the included hook for hands-free operation during busy field tasks
