New digital manifold for tough applications on refrigeration systems and heat pumps

Especially in the fields of service and maintenance, but also when commissioning systems, time is of the essence, and expensive. In the future, the new digital manifold testo 550 from the measurement technology specialist Testo AG will allow time-saving measurements and is a low-budget alternative to the previously used analog manifolds.

testo 550 measures high and low pressure quickly and precisely, and simultaneously calculates the temperatures. The brightly illuminated display allows fast and easy readout of all measurement values. There are 30 refrigerants stored in the instrument, which can be easily selected via a direct button.
Two temperature inputs allow the simultaneous calculation and display of superheating and subcooling. A clamp probe for fast and easy temperature measurements on pipes is included in delivery.

Reliable commissioning
The electronic manifold testo 550 informs the user of the vacuum reached when evacuating a system. In addition to this, a temperature-compensated tightness test of the system can be carried out using the measuring instrument. By measuring the system pressure and the ambient temperature over a defined period, the user can make a statement on the tightness of a system. This allows additional commissioning work to be carried out reliably with the testo 550.
