Description PCE-HT 71N Data LoggerMini device for 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-HT 71N Data Logger detects air temperature and humidity and stores readings in its internal memory. The Data Logger has a compact format and a wide memory capacity (up to 32,000 values / 16,000 values for each parameter) and it is mainly used as a data logger in fields such as supermarket refrigeration units, refrigerated transport, warehouses, and other temperature controlled environments. The Data Logger works as a data logger to record climatological data in spaces with controlled ambient conditions. Data can be transferred to a computer or a laptop via the USB port. The PCE-HT 71N Data Logger can be manually activated or can be programmed to start and stop on specific dates and times or to set the intervals at which measurements will be taken, allowing it to be left to record data in situ. Once transferred, data can be analysed on a computer. The software included in the delivery also calculates dew point. The internal clock allows the user to accurately assess the results. One special characteristic of the PCE-HT 71N is that it is powered by a removable 3.6V, long-life lithium battery. The battery life is approximately one year.
