The thermometer records the air temperature as well as the relative humidity and the barometric pressure and saves them internally on an SD card. The compact device with a large memory (up to max. 16 GB SDHC card) is primarily used for long-term registration in the food sector (refrigerated counters in department stores, refrigerated transports, warehouses) and for measurement and recording in industry (heating and cooling processes, machine temperatures, product storage). The current measured value is shown directly on the LCD display and is also stored in the data memory so that the value can either be read off directly or the values ​​stored on the SD card can be transferred to a PC or laptop as desired and evaluated graphically as a progression curve.

The values ​​recorded in the data logger function can of course also be transferred back to the PC and evaluated (.xls file on the SD card). You can also check the columns of numbers for outliers and, in the case of the food industry, quickly see whether and, if so, how long the cold chain was interrupted. The internal real-time clock with date allows the user to precisely assign the events. The measuring rate is freely adjustable. The electronics of the data logger are protected against impacts and robust handling in industry.
