CPS Products Automatic Programmable Charging Scale.

 Programmable high capacity 220lb/100kg Compute-A-Charge refrigerant charging/recovery scale, calibrated to strict NIST standards. Operating exclusively on two 9V alkaline batteries, the CC800A is the only fully automatic refrigerant scale that does not require line voltage and is R-410A compatible. Using the keypad controls, simply program the CC800A to transfer or recover a pre-set amount of refrigerant, hit go and walk away. The scale's advanced microcomputer circuitry will constantly monitor the progress of the job, shutting off the refrigerant flow when the pre-set amount is obtained and audibly alert the user. A large, highly visible 1 1?2" x 2" / 37mm x 48mm high resolution LCD readout displays either Imperial or Metric measurements in .25oz / 10g increments. The ergonomic hand held remote incorporates a 6ft coil cord, a hanging hook and is backed with a magnet for attachment to metal surfaces. Full mechanical and visual overload protection. Operates 30 continuous hours on two 9V alkaline batteries. Automatic off feature.
