More info
The hygrometer is a versatile tool at an affordable price. It is useful for measuring environmental factors such as temperature and relative humidity, as well as the surface temperature of walls or materials. The information is displayed directly on the unit's screen, as well as the maximum and minimum values. This allows the user to record the values for further analysis, or send them in real time to a portable or desktop device. This feature is useful in preventing mold growth in warehouses. It is also useful in the construction sector, since customers have the possibility to measure the temperature of the wall both internally and externally. It is used in industry to verify the quality of products. It also comes with a calibration kit so that the user can verify the meter himself, or it can be calibrated in a DIN ISO accredited laboratory. Of course, the ISO calibration service is also offered, for the first time or for periodic recalibration. Manufactured by PCE with reference PCE-320.

Technical terms
- Hygrometer
- DIN
A hygrometer is a precision instrument designed to measure relative humidity in the atmosphere or within specific technical enclosures using water vapor sensitive transducers.
Implementation of these devices in modern systems is primarily based on the variation of physical properties in dielectric or semiconductor materials. In industrial environments and data centers, electronic hygrometers utilize capacitive or resistive sensors that modify their impedance proportionally to environmental saturation. This data is processed via microcontrollers to facilitate real-time monitoring and automation of HVAC systems through industrial communication protocols.

The integration of digital hygrometers into critical infrastructure enables proactive condensation management, a decisive factor in preventing corrosion-related failures and short circuits in high-density hardware. Their recent evolution toward MEMS technology has facilitated miniaturization and the incorporation of these sensors into massive IoT deployments, where energy efficiency and long-term stability are fundamental requirements for predictive maintenance.
Capacitive Transduction Technology
Most advanced electronic hygrometers employ a dielectric polymer placed between two electrodes. As it absorbs water vapor, the polymer's dielectric constant changes, altering the circuit's total capacitance. This method is noted for its linearity and relative resistance to chemical contaminants.
Main Advantages
- High thermal stability across wide operating ranges.
- Low power consumption, ideal for remote sensors.
- Direct integration capability with PLC control systems.
- Fast response to critical humidity fluctuations.
Note: Periodic calibration under traceable standards is necessary to mitigate sensor drift.
