HVAC/R Mechanic-Turned Inventor Aims to Kill Old Analog Gauges
In 1987, Digi-Cool’s founder Doug Lockhart, a HVAC/R mechanic and inventor, decided that instead of staying frustrated with the poor accuracy and limited diagnostic power of analog gauges, he would get even. Analog gauges simply couldn’t keep up with the increasing complexity of refrigeration systems, leading to Digi-Cool’s introduction of one of the first successful digital analyzers. Since then Digi-Cool’s mission has been simple: develop digital analyzers that provide superior information about complex refrigeration systems in an easy, readable format. Now, with Digi-Cool’s new AK-900 (the Analog Killer), Lockhart’s company aims to finish off analog gauges for good. With a competitive price, far-reaching diagnostic power, and an intuitive no-toggling screen, Digi-Cool makes adaptation from traditional needle gauges to the deadly accurate AK-900 an easy choice for mechanics. The AK-900 has a series of improved features: • Faster, intuitive diagnostic readings on the AK-900’s large “no-toggle” LCD screen. With the AK-900, you won’t have to toggle between screens to access SH (superheat) and SC (subcool), giving you a complete analysis of complex refrigeration systems at a single glance. • Patented “dynamic offset bar-graph display.” This is the famous Digi-Cool display innovation that shows movement in .25 psi increments on the low side, helping you spot potential larger system problems such as leaks and compressor failures. • More refrigerant profiles and deadly accuracy. With over 30+ common refrigerant profiles on-board and a 0.5% accuracy, the AK-900 helps mechanics make fast, accurate service-calls. The unit has been designed and tested to ensure that it is tough enough to set the standard for digital analyzers for years to come. The AK-900 has a custom engineered plastic encasement, simple design with no buttons or knobs to break-off, and has undergone heavy-duty testing by DigiCool engineers. The unit is oil-proof, water-proof, acid-proof, and has survived a series of “torture tests”: beaten with a hammer, run over by a pick-up truck, and dropped off more than one two-storey buildings. While the AK-900 is the next stage of Digi-Cool’s evolution, the overall philosophy of the company remains the same: design digital refrigeration tools that help mechanics provide high-value services for their clients, and increase profitability with few or no callbacks. The AK-900 made its official debut at the 2011 AHR Expo in Las Vegas (January 28th- February 1st). Visit Digi-Cool.com for more information.
