The Testo 550 is a professional two-way meter for measuring heating and cooling systems. For professionals working with refrigeration systems and heat pumps.
Digital manifold Testo 550:
- Accurately performs high and low pressure measurements with two temperature-compensated pressure sensors.
- Automatically sets evaporation and condensation temperatures
- Calculates overheating and cooling simultaneously with two temperature inputs
- Sold with two temperature clamps: when attached to the measuring points, this allows reliable surface temperature measurement
- No need to switch cooling hoses: thanks to automatic heat pump mode
- Offers other features such as temperature compensated leakage test
- With remote monitoring capability: you can monitor the measurements from your smartphone/tablet, so you don’t have to stay close to the device. Up to 20 m away – no interference
