خلاء سنج دیجیتال- testo 552

The testo 552 is a high-precision digital vacuum gauge designed to provide you with absolutely reliable readings. It has all the measuring functions you need for evacuating refrigerant systems and heat pumps and is built to last and tough enough to take the odd knock.

The testo 552 is also the only digital vacuum gauge on the market with an absolute pressure senor which – in contrast to other sensor technologies – is maintenance-free while still being able to provide you with 100 percent reliable readings.

Product benefits:

  • The only digital vacuum gauge of its kind with maintenance-free yet high-precision absolute pressure sensor
  • 2 400 hours of battery power for 100 days of continuous operation
  • Extremely precise, extremely rugged, extremely practical – with visual alarm and backlit display
  • Measures pressure and calculates the evaporation temperature of H2O automatically
  • Measuring range:1100 to 0 mbar /
    825080 to 0 micron
  • Accuracy:0 to 1.33 hPa / 0 to 1000 micron : up to ±10 micron
    0 to 200 hPa / 0 to 150000 micron : ±0.3% FS = ±0.6 hPa
    200 to 1100 hPa / 150000 to 825080 micron : ±0.3% FS = ±3.3 hPa
  • Resolution:0.01 hPa / 10 micron
  • Overload:absolute: 6.0 bar / 87 psi
    (relative: 5.0 bar / 72 psi)
