Testo 570-2 Digital Manifold Gauge Meter Kit 4 Valves with 2 Clamps Refrigeration  Pressure Gauge Data Storage Internal Vacuum Sesor Testo 0563 5702 Product Description The testo 570-2 digital manifold gauge won’t just take the weight off your mind – it will also take the weight off your arms and shoulders. That’s because the testo 570-2 can replace a whole array of different tools and measuring instruments that you would otherwise need to carry around with when you work on refrigeration systems and heating pumps. The manifold gauge can measure, analyze and log pressure, temperature, electricity and vacuum measurements and save all measuring data. From the moment the unit was first used to servicing and maintenance to the fault analysis of a system.       Temperature          Measuring range    -50 to +150 °C        Accuracy    ±0.5 °C (±1 Digit)        Resolution    0.1 °C        Probe connection    3 x Plug-in (NTC)                 Pressure measurement          Measuring range    50 bar        Accuracy    ±0.5 % fs (±1 Digit)        Resolution    0.01 bar / 0.1 psi        Probe connection    3 x 7/16" – UNF + 1 x 5/8'' – UNF        Overload rel.
