PCE-HT71 Climatological Recorder with USB port
mini device for the prolonged measurement of temperature and relative humidity, 32k memory, USB port, software to calculate dew point, powered by a long-life lithium battery

The PCE-HT71 climatological recorder detects air temperature and humidity and stores readings to its internal memory. This climatological recorder is compact and has enough memory to store up to 32,000 readings, 16,000 for each parameter, and is used above all as a data logger in supermarket refrigeration units, refrigerated transport, warehouses and other temperature controlled environments. The device works as a data logger that records climatological data in spaces with controlled conditions. Data can be transfered to a computer via the USB port. The device can be manually activated or can be pre-programmed to start and stop on specific dates and times. The intervals at which measurements are supposed to be taken can be set, allowing it to be left to record data unsupervised. Once transfered, data can be analysed on a computer. The software also calculates the dew point. The internal clock allows the user to accurately assess the results. One special characteristic is that the device is powered by a removeable 3.6V, long-life lithium battery. Depending on how often the device is used, the battery could last up to a year.
