They are used daily for air conditioning and refrigeration systems as well as heat pumps. In this case, the testo 550 digital installation aid set is your ideal companion. Take a look at all the benefits at a glance:
 

• Rapid, precise measurement of high and low pressure with two temperature-compensated pressure sensors; automatic determination of evaporation and condensation temperature
• Two temperature inputs for connectable temperature sensors for simultaneous calculation of superheating and undercooling: This eliminates the need for manual calculations prone to errors and gives you a reliable result immediately
• Includes 3 filling hoses (blue, red, yellow) each 1.5 m in length, 7⁄16" UNF (straight and 45° angled) and 55/275 bar, suitable for all common refrigerants
• Two clamp temperature sensors included in the scope of delivery: allow reliable measurements of the surface temperature to take place when clamped directly to the cables
• No need to change refrigerant hoses: thanks to automatic heat pump mode
• 60 refrigerants stored in the unit: you cover the most important refrigerants with just one unit and do not need to use different installation aids depending on the refrigerant (refrigerant update possible with app)
