Copeland QT2000 Acid Test R-410A The gas valve manifold pressureThe Copeland QT2000 Acid Test, also known as the QwikCheck 2 second acid test, is a critical diagnostic tool for any technician performing preventative maintenance or diagnosing a compressor burnout. This kit allows for the near instant detection of inorganic acid in HVACR systems, yielding results in as little as two seconds with sensitivity down to 1 part per million (ppm). Unlike traditional titration kits that require oil samples, this refrigerant
