Máy đo nhiệt độ, độ ẩm PCE-HT 71N

PCE-HT71 air humidity meter with USB port USB
mini 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-HT71 air humidity meter detects air temperature and humidity and stores readings in its internal memory. This PCE-HT71 air humidity meter 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 supermarket refrigeration units, refrigerated transport, warehouses and other temperature controlled environments for PC. The PCE-HT71 air humidity meter works as a data logger to record climatological data in spaces with controlled ambient conditions. Data can be transfered to a computer or a laptop via the USB port.  The PCE-HT71 air humidity meter can be manually activated or can be previously programmed to start and stop on specific dates and times as well as setting the intervals at which measurements will be taken, allowing it to be left to record data in situ. Once transfered, 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 is that the PCE-HT71 is powered by a removeable 3.6V, long-life lithium battery. The battery life is approx. one year.
