Dynamic ‘Bar-Graph’ Technology

Protected by two international patents, this technology provides real-time data updates, allowing you to monitor pressure dynamics closely. Each segment in the low side bar graph represents ¼ psi (2 kPa, 0.02 bars) of change in the low side reading. On the high side, each segment represents 1psi (8 kPa, 0.08 bars) of change in the high side reading.

• Pipe-mounted Temperature Probes

  Gives you automatic SuperHeat and SubCooling readings.

  1SEC / 5SEC / HOLD

  Select the time between updates of the numeric pressure reading and corresponding temperature displays.

  Large LCD screen

  It’s a pain to have to run back and forth trying to read tiny digits on a screen. We know that. This screen will make your life a little easier.

  Backlight

  Easy to see and makes your job a little easier in any condition.

  Pressure recall modes

  These help with setting switching equipment and observing load changes over long periods.

  Tactile response keypad

  Made to be easy to operate with gloves and cold hands.

  ‘No-toggle’ screen

  It‘s annoying to have to toggle back and forth to see SH + SC. With the AK-900, you’ll be able to analyze all your important data collected in one highly readable place.

Absolute zero

The AK-900 can zero the pressure readouts to absolute zero and thus read accurately in high altitude locations.

Sensing accuracy

0.6% FS ± 1 least significant digit.

Temperature accuracy

±0.9°F (±0.5°C) between 32 to 158°F (0 to 70°C).

Temperature sensor range

-40 to 250°F (-40 to 125°C).

Dual Temperature Sensors and Delta T

Dual temperature sensor assembly and the ability to switch not only back and forth between SH + SC but to read a ‘dt’ or delta temperature as the blue lead (SC) sensor temperature is subtracted from the read lead (SC) sensor.

Tough, weather resistant case

Really tough. Designed for indoor / outdoor field use. Tested to the extreme with Digi-Cool’s ‘Torture Tests.’
