Measuring hygrometry in high-humidity environments

Accurate and stable results

Some pharmaceutical or research establishments, and some industries (paper, paint, food, etc.) operate in premises with high humidity. Measuring hygrometry in these environments requires specific probes.

For these environments, Sauermann has appropriate solutions to ensure good hygrometry measurements in areas with high humidity, where the phenomenon of condensation is particularly disruptive and even dangerous for sensitive instrument components.

Parameters to be monitored

  • Hygrometry

  • Temperature

  • Psychrometric values

CHOOSING THE RIGHT PROBE
Temperature variations in environments with high humidity produce condensation. This residual water can interfere with measurements, so precautions need to be taken: choose the right type of temperature and humidity probes, and make sure they are protected.
Our Si-PRO-U-I-100-H temperature and hygrometry probe is heated to prevent condensation forming on the sensitive element. Coupled with an external temperature sensor, it will accurately measure all psychrometric values.

POSITIONING THE PROBES
In a room, the hygrometry probe is installed in an open area where the air is not confined, away from heat sources, hot or cold air flows and sunlight. In ducts, the sensor should be placed horizontally 1/3 of the duct diameter.
To avoid any heat loss through the body of the probe, it is essential to choose a probe of appropriate length. Sauermann offers hygrometry measurement probes in polycarbonate or stainless steel with lengths of 150 or 300 mm, which can be fitted with specific protection ends.

PROBE PROTECTION
In harsh environments, hygrometry probes need to be protected. These protections prevent the risk of deterioration or premature drift of the probes' sensitive element, guaranteeing measurement accuracy and stability.
Two types of probe protection predominate. Some specific end caps protect against dust and condensation, and for unheated probes positioned in an ambient environment (relative humidity >80% at over 30°C), ventilation must maintain a constant air flow to prevent condensation from forming.

In production or storage areas, mapping in accordance with standard FD X15-140 identifies all the hot spots, cold spots and homogeneity of the building. This enables the best locations for measurements to be determined with pinpoint accuracy.
In environments where measuring elements (housings, probes, etc.) are constantly subjected to high levels of physical stress, Sauermann's teams can help you carry out on-site periodic checks and calibration of your temperature and hygrometry sensors.
