A stable indoor climate plays an important role in the quality of the stay and the quality and durability of certain goods. If temperature and humidity vary in production and storage facilities, the quality of sensitive products, such as food or pharmaceutical products, suffers massively. A temperature/humidity logger is the perfect accessory for continuous monitoring of the ambient conditions.

The humidity logger records and documents reliably, effective and precise indoor temperature and humidity, and also shows them on the well-readable display. The display can be switched off to save the batteries. A fold-out stand on the back of the humidity logger ensures a secure stand on horizontal surfaces. Alternatively, the measuring device can also be wall-mounted. A temperature/humidity logger enables recording and documenting of all essential room climate data in living rooms, offices, workshops and storage rooms.

The temperature range for the temperature humidity logger ranges from - 30 ... +65 °C, the humidity measuring range of 0 ... 100 % r.F. By means of the integrated sensor the temperature/humidity logger records both the measured values, records the measured values and also shows them clearly visible on the large LC-display. In its large data storage, the temperature-humidity logger can secure up to 25,920 measured values. The user can connect the humidity logger with a PC and read the stored data via USB port. The analysis software clearly displays the measuring process in a graphic. All measurements are also listed in a report. The temperature humidity logger offers the option of setting alarms for limit values. If the preset minimum temperature and relative air humidity values are not reached or the maximum values are exceeded, the temperature/humidity logger emits an acoustic signal. Thus, the responses can be fast, without having to continuously observe the values on the display. Pre-set limits are 2 °C and 35 °C for the temperature and 30 % and 75 % for the relative humidity. The values can be changed via the software.

Application areas for the temperature/humidity logger
Temperature humidity loggers support the user in complying with industry-specific specifications and quality requirements. In many industrial branches, temperature/humidity loggers are used for different applications. However, the measuring devices are also used for monitoring the environmental conditions in offices, laboratories, museums, schools and warehouses. Temperature humidity loggers help to use energy efficiently and thus save money. This makes them popular with tenants and homeowners who want to control their heating and ventilation preferences. Temperature humidity loggers are used whenever measuring data must be recorded continuously, but the continuous presence of persons is not necessary or desirable. At the same time, the current measured value can also be read from the large display at any time. The PCE Instruments temperature/humidity logger ensures professional monitoring of temperature and relative humidity, is easy to use and flexible to use. Thanks to its compact size (96 x 108 x 20 mm), the temperature and humidity logger can be quickly used anywhere. The easy to use software guarantees simple handling and allows even inexperienced users to adapt the memory interval and limit values to the concrete local conditions. Also the control of recorded values is simplified by the software.

ISO calibration for temperature humidity logger
PCE instruments also offer the ISO calibration for temperature/humidity loggers. If you order the temperature/humidity logger with calibration certificate, the device will be calibrated in our calibration laboratory before delivery. Calibration certificates are specially issued to the customer, so that the delivery time is somewhat longer. The periodic recalibration required to comply with DIN ISO 9000 can also be performed in the PCE Instruments calibration laboratory. You can also send the temperature-humidity logger to any other certified laboratory for calibration. Keep in mind that the measuring device will then not be available to you for a few days. Regular monitoring ensures that the accuracy of the temperature/humidity logger is accurate and documented. This is especially important if the temperature humidity logger is to be included in the test pool of an ISO-certified company.

The calibration intervals must be determined according to operational requirements. In particular, the operating conditions and the effects of incorrect measurements play a role. If calibration requirements are increased, the temperature/humidity logger can also be calibrated to DAkkS standards in accordance with DIN EN ISO/IEC 17025.

The ISO calibration certificate reproduces the measurement accuracy for the tested temperature/humidity logger by comparison measurement at 3 points for humidity and temperature. To do this, a thermohygrometer with an external calibration is positioned in the climate control cabinet and exposed to the same climatic conditions.

PCE Instruments typically tests the three temperature measurement points at about 15°C, 25°C and 35°C and relative humidity at about 30%, 50%, and 80%. The two climate loggers are exposed to the respective climatic conditions for at least 30 minutes for each calibration point. The values for temperature and humidity are specified in the calibration certificate in tables with the following structure:

Temperature / Temperature target value / Target value [°C] Actual value / Actual value [°C] Deviation / Deviation [K] Result / Result 0.1 / 15.5 15.4 / 15.4 - 0.1 / - 0.1 IO / pass 23.7 / 23.7 23.6 / 23.6 - 0.1 / - 15.5 OK / pass 35.7 / 35.7 35.4 / 35.4 - 0.3 / - 0.3 ok / Pass At 30 % r.h. ± 5 % r.h. Tolerance / Tolerance ± 0.3 °C / ± 0.3 °C In this example, the three values for the temperature are within the measurement tolerance of ± 0.3 °C given for the PCE-HT 112 Humidity / humidity target value / target value [°C] actual value / actual value [°C] deviation / deviation [K] result / result 15.5 / 15.5 15.4 / 15.4 - 0.1 / - 0.1 IO / pass 23.7 / 0.1 / 23.6 - 0.1 / - 23.7 23.6 IO / pass 35.7 / 35.7 35.4 / 35.4 - 0.3 / - 0.3 ok / Pass At 22 °C ± 1 K tolerance / tolerance ± 3 % r.h.

The measured humidity values here are also within the tolerance of ± 3 % r.h. given for the temperature humidity logger at -0.1 % and -0.3 % If all measured values are not within the specified tolerance during calibration in our laboratory, we will contact the customer and offer him the adjustment or repair of the device. Most times, the temperature/humidity logger can measure again with the desired accuracy after an adjustment.
