Testo Set professionale per pompe di calore 558s – pressione, vuoto, temperatura (0564 1051)

Digital manifold set for heat pump systems, refrigeration, and air conditioning, combining pressure, vacuum, and temperature measurement in one kit. The Testo 558s digital manifold provides a pressure measurement range of -1 to 60 bar and temperature measurement from -50 to +150 °C. The included Testo 552i wireless vacuum probe measures vacuum from 0 to 20000 micron (0 to 26.66 mbar). Bluetooth 5.0 connectivity enables wireless data transfer to the Testo Smart App on iOS and Android devices. The manifold features a large graphic display and is powered by 4 x AA batteries with approximately 10 hours of battery life. The set includes 2x Testo 115i clamp thermometers, 2x Testo 605i thermo-hygrometers, 1x Testo 552i vacuum probe, 1x Testo 549i high-pressure probe, 1x Testo 510i differential pressure probe, and a Testo Smart Case for heat pump applications. The refrigerant database stores over 90 common refrigerants. Calculated parameters include high/low pressure, evaporation/condensation temperature, superheating/subcooling, vacuum, ambient temperature, relative humidity, and differential pressure. Pressure sensor accuracy is ±0.5 % of full scale. The manifold has an operating temperature range of -20 to +50 °C and protection class IP54.
