Compute-a-Charge^® Refrigerant Charging Scales deliver the accuracy and repeatability HVACR technicians need for critical charging and recovery work. Built with advanced load cell technology and calibrated to strict NIST standards, these industry-leading scales support precise refrigerant measurement across residential and commercial systems. With high-capacity options, programmable controls and wireless functionality, Compute-a-Charge scales help technicians charge with confidence job after job.

Precise refrigerant charging by weight is essential for system performance, efficiency and long-term reliability — especially as tolerances tighten and system complexity increases. Compute-a-Charge^® HVACR charging scales are engineered with advanced strain-gage load cell technology to deliver unmatched accuracy, stability and repeatability in real-world field conditions. Each scale is calibrated to NIST (National Institute of Standards & Technology) standards, ensuring defensible measurements during charging, recovery and evacuation procedures.

The Compute-a-Charge lineup includes 110 lb and 220 lb high-capacity refrigerant scales, programmable models with integrated solenoid control and wireless charging scales that pair with the CPS Link™ app for automated charging, refrigerant tracking and EPA-compliant recordkeeping. Select models integrate with the SVW Bluetooth^® Wireless Solenoid Valve, enabling precise, hands-free control of refrigerant flow. Built with rugged cast aluminum platforms and designed to perform in demanding environments, Compute-a-Charge scales are trusted by HVACR professionals who require accuracy without compromise.
