The Class 1 IoT data logger can be used, e.g, for sound measurement of street noise, aircraft and train noise, event noise, noise coming from construction sites, ports, factories involving heavy machinery, airport/bus stations, stadiums, horse/motor racing tracks etc. The weather conditions do not matter, and hail, snow, rain and similar are no problem for this system for outdoor noise monitoring. The IoT data logger is equipped with a GPS receiver which allows the user to assign the measured values to an exact position.

The PCE-HT 71N Data Logger detects air temperature and humidity and stores readings to its internal memory. This Data Logger 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. These temperature and humidity logging test instruments are manufacturer calibrated. An ISO calibration certificate is an option.
