ORLANDO, Fla. - The new TestoKool 523 is a low-cost digital gauge set that lets technicians quickly and accurately service A/C, refrigeration, and heat-pump systems, says the company. Its sensors allow for precise measurement of high and low side pressures and saturation temperatures for up to 38 built-in refrigerants, the company says.

Superheat and subcooling values are calculated automatically with a line temperature probe eliminating extra steps. All readings are displayed on a backlit LCD.
