Residual moisture measurement

Thin humidity probe incl. 4 attachable protection caps for ambient air measurements, measurements in exhaust air ducts and equilibrium moisture measurements

High humidity level probe w/ heated sensor element, no humidity on sensor

The slim humidity probe measures material moisture via the equilibrium moisture content and can very easily be used in recesses or bore holes thanks to its slim design and remote electronics. The material moisture can also be determined directly in the instrument in combination with the testo 635 temperature and humidity measuring instrument.

 

• Measurement of the material moisture via the equilibrium moisture content

• Slim design (Ø 4 mm) with remote electronics – ideal for tight measuring points

In combination with the testo 635, the robust humidity probe measures the humidity and temperature of the air. Because the probe can be used up to 125 °C, it also enables measurements in air exhaust ducts. In addition, it is suitable for measuring the material equilibrium moisture content, for example in bulk materials.

• Probe for relative humidity and air temperature measurements

• Measurements of the material equilibrium moisture content possible

• Temperature measuring range: -20 to +125 °C (briefly up to +140 °C)

The ideal probe for measuring the humidity and temperature of the air in storage, refrigerated and work areas, as well as in air conditioning/ventilation ducts. Also suitable for long-term measurements.

• Humidity sensor with long-term stability

• Temperature measuring range: -20 to +70 °C

The humidity module can be attached to various Testo radio handles. It enables a high level of accuracy thanks to the precise humidity sensor.

Humidity module, upgradeable for testo 845

Pressure dewpoint probe for measurements in compressed air systems

Check compressed air lines reliably: the precision pressure dew point probe with measuring chamber is ideally suited for fast and accurate determination of the pressure dew point and for high-precision measurements in the trace humidity range.

• Fast and accurate determination of the pressure dew point

• Robust humidity sensor with long-term stability 

• Connection to the compressed air system via standard plug-in connection

• Measuring range: -40 to +50 °C tpd

Standard pressure dewpoint probe for measurements in compressed air systems

This robust humidity probe can be used for the simultaneous measurement of temperature and relative humidity. The probe's wide temperature range of up to +180 °C means that you can measure the moisture content in industrial exhaust air, for example.

• Robust humidity probe measures temperature and relative humidity

• Measurements are possible up to +180 °C, for example in industrial exhaust air or in air-conditioning cabinets

• Automatic calculation of absolute humidity, dew point, wet bulb temperature and enthalpy

• Zero-error display thanks to an intelligent calibration concept

The ideal probe for fast and accurate determination of the pressure dew point. In addition, it is suitable for high-precision measurements in the trace humidity range and also enables fine adjustment to any pressure dew point in the -40 to +25 °C tpd range at +25 °C (single-point adjustment).

• Fast and accurate determination of the pressure dew point 

• High-precision trace humidity measurement

• Pressure dew point measuring range: -40 to +50 °C tpd
