PCE Instruments PCE-HT 112 PCE-HT 112 Multi-channel data logger 0 up to 100 RH

Climate logger PCE-HT 112 for temperature and humidity Climate logger for temperature and humidity / LCD / memory for 25,920 measured values / fast reading via USB / adjustable alarm limit values A stable room climate plays an important role for 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 medicines suffers massively. An ideal tool for continuous monitoring of the ambient conditions is a climate logger. The PCE-HT 112 records and documents reliably, effectively and precisely temperature and humidity in indoor areas and also shows them on the easy-to-read display. This display can be switched off to protect the batteries. A folding stand on the back of the air-conditioning logger ensures a secure stand on horizontal surfaces. Alternatively, the measuring device can also be wall-mounted. With a climate logger, the most important room climate data in living rooms, offices, workshops and storage rooms can be recorded and documented. The temperature measuring range of the PCE-HT 112 ranges from - 30 to 65 degrees Celsius, the air humidity measuring range from 0 to 100 percent relative humidity. Via the integrated sensor, the air-conditioning logger records both measured variables, records the measured values and also shows them clearly on the large LC display. In its large data memory, the climate logger can save up to 25,920 measured values. The user can connect the climate logger to a PC via a USB interface and read the stored data. The measurement process is clearly displayed in a graphic using the evaluation software. All measurements are also listed in a report. The climate logger offers the option of setting alarms for limit values. If the preset minimum values for temperature and relative humidity are undercut or the maximum values are exceeded, the air-conditioning logger emits an acoustic signal. This allows quick response without having to constantly monitor the values on the display. The default values 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. Short characteristic of PCE-HT 112 - Climate data logger for temperature and humidity with internal sensor - easy to read LCD display with different display options - adjustable alarm limit values - memory for 25,920 measured values, Storage interval can be selected - fast reading via USB-interface - associated evaluation software - power supply via 3 x 1.5 V AAA batteries or via USB-cable Application areas for the air-conditioning logger Air-conditioning system support the user in complying with industry-specific specifications and quality requirements. In many branches of industry, climate data logger is used for different purposes. The measuring instruments are also used, for example, in offices, laboratories, museums, schools and warehouses to monitor the environmental conditions. Climate data logger helps to use energy efficiently and thus save costs. This is why they are also popular with tenants and homeowners who want to control their own heating and ventilation behavior. Climate data logger is used whenever measurement data must be recorded permanently, but the permanent presence of persons is not necessary or desired. At the same time, the current measured value can also be read from the large display at any time. PCE Instruments' climate logger ensures professional temperature and relative humidity monitoring, is easy to use and can be used flexibly. Because of its compact size (96 x 108 x 20 mm) the air-conditioning logger is ready for use everywhere quickly. The easy-to-use software guarantees easy handling and allows even inexperienced users to adapt the storage interval and limit values to the specific local conditions. The control of recorded values is also simplified by the software. ISO calibration for the air-conditioning logger PCE-HT 112 PCE Instruments offers ISO calibration for air-conditioning systems. If you order the PCE-HT 112 climate logger with a calibration certificate, the device is calibrated in our calibration laboratory before delivery. Calibration certificates are issued specifically to the customer, so that the delivery time is slightly longer. The recalibration at regular intervals required to comply with DIN ISO 9000 can also be performed in the PCE Instruments calibration laboratory. You can also send the climate logger to any other certified laboratory for calibration. Please note that the measuring device will not be available for a few days. The measurement accuracy of the air-conditioning system can be secured and documented by regular monitoring. This is particularly important if the climate logger is to be included in the test equipment pool of an ISO certified company. The intervals for calibration must be defined according to operational requirements. In particular, the operating conditions and the effects of incorrect measurements play a role. If there are increased requirements for calibration, the air-conditioning logger can also be calibrated according to DAkkS according to DIN EN ISO/IEC 17025. The ISO calibration certificate shows the measuring accuracy for the tested climate logger by means of comparative measurement at 3 points each for humidity and temperature. For this purpose, together with the PCE-HT 112 air conditioner, an externally calibrated thermo-hygrometer is positioned in the air conditioning 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 data logger will be exposed to the respective climatic conditions for each calibration point for at least 30 minutes. The calibration certificate specifies the values for temperature and humidity in tables with the following structure: Temperature / Temperature set value / Target value [°C] is value / Actual value [°C] Deviation / Deviation [K] Result / Result 15.5 / 15.5 15.4 / 15.4 - 0.1 / - 0.1 OK / pass 23.7 / 23.6 / 23.6 / 23.6 - 0.1 / - 0.1 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 specified for the PCE-HT 112 Humidity / Humidity should-value / Target value [°C] is-value / Actual value [°C] Deviation / Deviation [K] Result / Result 15.5 / 15.5 15.4 / 15.4 - 0.1 / - 0.1 / - 0.1 i. o. / pass 23.7 / 23.7 / 23.6 / 23.6 - 0.1 / - 0.1 i.o. / 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 humidity readings are also within the tolerance of ± 3% RH for PCE-HT 112, at -0.1% and -0.3% If during calibration in our laboratory not all measured values are within the specified tolerance, we contact the customer and offer him the adjustment or repair of the device. Usually, the climate logger can again measure with the desired accuracy after an adjustment.
