CPS Products A/C System Diagnostic Tools: Built by Technicians, for Technicians
When it comes to diagnosing automotive air conditioning systems with confidence, few names carry the credibility of CPS Products. Founded in 1989, CPS has earned its reputation as a world leader in A/C and refrigeration service equipment — a brand whose engineering is rooted in real-world shop experience. Their A/C System Diagnostic Tools reflect that same hands-on philosophy: purpose-built instruments designed to give technicians clear, actionable data rather than guesswork.
Seeing the Invisible: The ACDIAGDUAL Diagnostic Tool
At the heart of CPS Products' automotive A/C diagnostic lineup is the ACDIAGDUAL — a professional refrigerant diagnostic tool engineered for both R-134a and R-1234yf systems. Rather than relying solely on pressure readings, this tool takes diagnostics a step further by giving technicians a direct visual window into refrigerant condition. The integrated sight glass allows users to identify excess dye, oil, or debris within the refrigerant stream — issues that pressure gauges alone simply can't reveal.
One of the ACDIAGDUAL's standout design principles is its commitment to zero refrigerant loss. The tool extracts a small refrigerant sample for inspection without venting it to atmosphere — ball valve controls ensure all extracted refrigerant is returned to the system after inspection. This approach not only protects the environment but also shields downstream A/C service machines from contamination that could damage internal components.
Smart Diagnostics Backed by Patented Technology
CPS Products' diagnostic philosophy extends well beyond a single tool. The brand has consistently led the industry in patent awards, developing the CPS Link™ platform — a powerful application that connects multiple wireless sensors simultaneously to create a comprehensive, real-time diagnostic measurement system. This patented ecosystem allows technicians to scale their diagnostic capability from a quick one-step measurement to a full system analysis with integrated analytics — all from a smartphone or tablet interface.
This commitment to smart, connected diagnostics makes CPS tools especially valuable in modern shops servicing today's increasingly complex A/C systems, including next-generation R-1234yf platforms found in late-model vehicles.
