NEW! Testo 557 Refrigeration System Analyzer with Vacuum Measurement

Looking for a detailed review of the Testo 557? Click HERE

The testo 557 four valve manifold with a built in vacuum measurement is the next high performance, low cost Refrigeration System Analyzer from testo. The built in vacuum measurement allows the technician to know when they have reached the limits when evacuating a system. Building upon the easy to use testo 550 platform, the 557 has 2 NTC temperature probe inputs and can simultaneously calculate superheat and subcooling in real time. The 557 is ideal for servicing, maintaining and commissioning all types of air conditioning systems. The 557 will also perform leak tests on AC/R systems with temperature compensation, insuring accurate results. The testo 557 retains the robust housing that protects the analyzer from the everyday bumps and drops. It comes complete with 2 clamp probes, integrated hook, built in hose holders and a hard carrying case.
 
Includes digital manifold, 2 clamp probes, batteries, calibration record and hard case
Features
  • Built in Vacuum Measurement
  • Aluminum valve block with 4 connections and built in sight glass
  • 2 temperature probe inputs for simultaneous real-time calculation of superheat and subcooling
  • Readings are displayed in seconds
  • Compact easy to use, transport, and setup
  • Large easy to read back-lit display
  • Robust housing that protects the analyzer
  • 40 Refrigerants on-board eliminating the need for PT charts
Sensors:
  • PSI / MPa / Bar / kPa
  • Temperature F / C / K
  • Vacuum Micron / Torr / inH2O / C / inHg / Pa
  • Sensors: Pressure 2 x pressure sensors
  • Temperature 2 x NTC
  • Hose connections 3 x 1/4 SAE, 1x 3/8 SAE
  • Each of the temperature probe leads are 4 feet 9 inches long, tip of clamp to end of wire.
Measuring ranges:
  • Pressure HP/LP (rel): -14.7 to 725 psi / -100 to 5000 kPa -0.1 to 5 MPa/ -1 to 50 bar
  • Temperature: -58 to 302F / -50 to +150C
  • Vacuum (rel) -1 to 0 bar
  • Overload pressure 52 bar, 5200 kPa, 5.2 MPa, 754 psi
Resolution:
  • Pressure 0.01 bar / 0.1 psi / 1 kPa / 0.001 MPa
  • Temperature 0.1C / 0.1F
  • Vacuum 1 hPa / 1 mBar / 0.5 Torr / 0.5 inH2O / 0.02 inHg / 500 Micron / 100 Pa Accuracy (@ 22C/71.6F):
  • Pressure 0.5% fs (1 digit)
  • Temperature 0.5 C (1 digit)
  • Vacuum 1% fs (1 digit)
NOTE: When testing the 557 and 570 we found the vacuum sensor resolution a little lackluster. A 500 micron resolution will tell you are in a vacuum, and if the gauge reads 0 microns you are somewhere below 500, but that is all. For high vacuum resolution we recommend the BluVac Digital Micron Gauge used with core tools to isolate hoses from the system.
