Page 4: User Instructions
The probes can be used, without a measuring chamber, in accordance with the Instruction Manual for the testo x35 instruments. By connecting the probe to testo x35 the user has a portable, mains independent measuring system. The large display enables the display of the relative humidity or the dew point with the temperature. -
Page 5: Safety Instructions
Safety instructions Read before using the instrument Please read the Instruction Manual belonging to the measuring instrument. Do not exceed the permissible pressure range. Observe the measuring range of the sensor. Overheating can destroy the probe. Observe the permissible storage and transport temperature as well as the permissible operating temperature (e.g. -
Page 6: Operating Instructions
Operating instructions The pressure dew point probe Place the measuring chamber on the humidity probe adapter and screw on tightly by hand. Valve to control the air flow rate Make sure that the measuring chamber and the valve are not dirty. Using the valve you are able to control the air flow rate which flows off to get an optimized response time with the humidity sensor... -
Page 7: Measuring
Measuring Please read the instrument instruction manual before the switching on the instrument, in order to avoid incorrect measuring results and damage to the instrument. The storage of the humidity probe in areas with temperature and humidity values which differ considerably from those of the compressed air being measured, and dirty sensors or sintered caps increase the response times. -
Page 8: Maintenance
Maintenance A robust, long-term stable humidity sensor is located in the probe head. Depending on the application and dirt which has gathered, we recommend a quarterly to yearly control with our 0554.0660 control and calibration set. See the instructions on page 10. Clean dirty sensors with alcohol (isopropanol) or distilled water. -
Page 9: Control And Calibration Options
“Relative humidity” and “Dew point” the values for the relative humidity over the saturated lithium chloride (LiCl) and sodium chloride (NaCl) solutions were newly specified at testo. LiCl 11.3%RH, NaCl 75.3%RH at rated temperature +25 °C These improved values also apply to all of the control and calibration sets already delivered. - Page 10 A control with the control and calibration set is possible. The salt containers are not suitable for calibrating the precision probe. A precision calibration can only be carried out at testo or with corresponding Protective highly accurate reference systems (dew point mirror sleeve measuring instruments for compressed air).
- Page 11 Control and calibration options Fine calibration With the probes 0636.9835 and 0636.9836 you have the option of a fine calibration on any pressure dew point in the range -50 to +25 °C t at +25 °C (one point calibration). Note...

Page 14: Necessary Pressure Dew Point Values T Pd
Appendix A Necessary pressure dew point values t Depending on the type of application, different requirements can be made on the air quality. As the speed of corrosion on steel surfaces increases rapidly above approx. 50%RH, this value should never be exceeded. Field of application Necessary pressure dew point values t Factory air, internal pipes... -
Page 15: Dew Point Graph For Compressed Air
Appendix B Dew point graph for compessed air This graph gives information on the change in the pressure dew point at pressure loss. A drop in working pressure from 8 bar to 6 bar is used as an example here. In this case the pressure dew point is reduced from 10 °C to 5 °C.
