Testo 557 Digital Manifold Kit with Bluetooth and 4 Filling Tubes

Overview

The Testo 557 digital manifold kit with Bluetooth® is a complete 4-way solution for refrigeration and air-conditioning technicians. In addition to two temperature-compensated pressure sensors and temperature inputs, it features an integrated vacuum sensor, so a single instrument covers pressure testing, superheat and subcooling calculation, and full evacuation of the system.

Pressure is measured from -1 to +60 bar with 0.5% full-scale accuracy across three 7/16″ UNF ports plus a 5/8″ UNF vacuum connection, and the testo Smart App adds documentation, reporting and a second display. Supplied with a set of four filling tubes, the testo 557 kit is ready to handle commissioning, servicing and maintenance straight out of the case.
