High-precision humidity and temperature probe
Application information
Pos: 1 /TD/Kurzanleitungen/testo 480/Hochpräzise Fe uchte- und Temperatur sonde 0635 0543 @ 9\mod_131 1248996131_79.doc @ 85593 @ 555 @ 1
The high-precision humidity and temperature probe 0636 9743 is used in conjunction with the testo 480 to measure humidity and temperature.
The control and adjustment set 0554 0660 is not suitable for adjustment. We recommend an annual calibration at Testo.

The digital probe allows measurement values to be processed directly in the probe. This technology eliminates instrument measurement uncertainty.
For calibration, the probe alone (without the hand instrument) can be sent away.
Calculating the determined calibration data in the probe generates a zero-error display.

The measurement uncertainty for the relative humidity was calculated according to GUM and includes hysteresis, dispersion, linearity, repeatability, uncertainties of adjustment and test site, display resolution. This does not include the uncertainty values of long-term stability and drift in the case of long­term high humidity measurement.
