Testo’s 550 Digital Manifold Kit with Bluetooth is the ideal solution for applications that require work on AC, refrigeration systems and heat pumps.
The 550 provides fast precision measurement of high and low pressure with two temperature compensated pressure sensors; automatic measurements of the evaporation and condensation temperature. Each unit is designed with two temperature inputs for fastening temperature pipe clamp probes. Simultaneous calculation of superheating and sub-cooling practically eliminates the risk of errors produced by manual calculations, providing reliable results quicker.
Each kit comes equipped with 3 5 ft. long, 7/16" UNF (straight and 45º angle) hoses (blue, red and yellow) and 2 pipe clamp temperature probes. The 550 is suited with an automatic heat pump mode - removing the hassle of switching over refrigerant hoses, a temperature compensated leakage test, display of temperature difference and more.
