PCE Instruments HT 71N Mini Hygro-thermometer Datalogger

Model # HT 71N

It 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.
It 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 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.

The PCE-HT 71N Hygrometer detects air temperature and humidity and stores readings in its internal memory. The Hygrometer 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 Hygrometer 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 Hygrometer 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 site. 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.
