Mastercool Accu-Charge II Electronic Refrigerant Scale (not authenticated)

The item depicted is a portable electronic refrigerant scale, housed within its original black blow-molded hard plastic carrying case. The unit features a rectangular weighing platform with a ribbed rubber mat surface and a central bubble level indicator. Attached via a coiled black cord is a handheld digital controller with a multi-line LCD screen, directional arrow buttons, and a color-coded membrane keypad including buttons labeled ON/OFF, UNITS, TARE, CLEAR, CHARGE/PAUSE, REPEAT, ENTER, and SHIFT. The interior lid of the case serves as a quick-reference guide featuring printed operating instructions, key functions, programming instructions, specifications, and calibration procedures. The handheld controller displays branding text reading 'Mastercool Inc.' and 'Accu-Charge II' alongside model number '98210-A'. The unit shows signs of moderate wear, including surface dust and minor scuffs on the platform and case, consistent with workshop or field use. The identification is based on the clearly legible brand name and model designations printed on the controller and instruction placard. The item appears to date from the late 20th to early 21st century based on the styling of the digital interface and plastics, though age and functional authenticity remain unverified.

Based on what I can see in the photograph, the item appears to be a Mastercool Accu-Charge II Electronic Refrigerant Scale, model 98210-A, housed within its hard plastic carrying case. The branding and model numbers are clearly legible on the handheld controller and internal placard, which forms the basis for this working assumption. However, I cannot verify functional operability, internal calibration accuracy, or the absolute authenticity of the unit from a photo alone. The tool exhibits moderate cosmetic wear, including surface dust and minor scuffs consistent with field use, which would be factored into a buyer's evaluation. In the current secondary market, used HVAC service tools of this type generally see steady demand among technicians and hobbyists looking for functional equipment at a discount compared to new retail units. If this unit is fully operational and the assumed identification holds true, comparable tools typically trade within the $150 to $250 range. To confirm authenticity and operational capability, an in-person physical inspection, functional testing with standard weights, and evaluation of the electronics by a qualified technician would be necessary. If the unit turns out to be non-functional, a replica, or otherwise compromised, its value would drop substantially, likely to scrap or parts value in the $30 to $50 range.
