Sparta, NJ (June 17, 2015) – Further improving on its digital manifolds for the servicing and commissioning of air conditioning and refrigeration systems, Testo has introduced its next-generation 557 Digital Manifold with remote vacuum probe and Bluetooth. With the Bluetooth, it gives users new possibilities for working faster, more comfortably, and therefore more efficiently.
Using the App, measurement data can be read and logged directly on a Smartphone or tablet, and measurement reports, in pdf or csv file format and integrated photos, can be finalized and sent via email directly from the job site. The list of 60 on-board stored refrigerants can also be easily updated via the App.
The testo 557 automatically selects the evacuation mode as soon as the user connects the new vacuum probe for faster and more reliable evacuations. The measuring range has been extended to 870 psi (60 bar) and the battery life has been increased to 250 hours. In addition, the size and weight have been reduced, making it easier to work with. Two NTC thermistor clamp probes are automatically recognized as soon as they are plugged in and provide superior accuracy of simultaneous, real-time superheat and sub-cooling readings.
