UEi AK900HC Refrigeration System Analyzer

Advanced, durable tool for the professional HVAC&R technician.

Digi-Cool offers unprecedented diagnostic power with the Digital Refrigeration System Analyzer (AK900). The patented pressure bar graphs allow you to see pressure dynamics intuitively for quick diagnosis. Automatic saturation, subcool and superheat readings mean no more wallet cards. Conceived by a technician with modern engineering, the unit will endure years of field use.
The new AK900 features an integrated dual temperature probe to automatically calculate superheat and subcool, and pressure extremes monitoring for simple pressure controls set-up, for even greater convenience during start-ups.

 

45 Pre-Programmed Refrigerant Profiles

HOW IT WORKS:

• Bar graph segments shows changes from digital reading
• Range of ±2psi on low-side, ±8psi on high-side
• In example below, low-side has dropped ½ psi to 99.8 psig since update, high-side has increased 7psi to 440psig since update
• Digital readings have ¼ psi resolution on low side, 1 psi resolution on high side
• Temperature directly below low and high side pressures are the corresponding dew point and bubble point temperatures for the corresponding pressures respectively. (Saturation temperature for pure compounds)
• Temperature with derived superheat are listed below the low side pressure/temperature readings whereas the temperature and derived subcooling are listed below the high side temperature (eg 72˚F sensor temp./41˚F superheat and 71˚F sensor temp./51˚F subcool)
• dt is calculated temperature of low side (SH) sensor subtracted from high side(SC) sensor.
• R-h / i selects active refrigerant
• ZERO automatically calibrates to current atmospheric pressure
• UNIT changes between traditional (PSI,“Hg, °F) and SI (kPa, bar, °C) units
• 1SEC / 5SEC / HOLD changes the rate digits are updated
• LCD h / i changes contrast to fit lighting conditions
• MIN / MAX CLR resets peak pressure memory
• MODE selects temperature, superheat, subcooling, max pressure, or min pressure displays
