<p> The wireless data loggers are suitable for a wide range of humidity and temperature monitoring tasks. Wireless transmission - possible over distances of up to 300m - saves the user wiring costs and the data can be collected and recorded from inaccessible points quickly and easily. Thanks to the combination of wireless transmission and data logging, the greatest possible reliability against failure is insured. Up to 100 devices can be connected and configured via HW4 software using an Ethernet or an USB receiver. </p><p> Industries such as building services, cleanroom research, pharmaceutical, chemical, Logistic and food and beverage are highly suitable for the application of the wireless logger to enhance their monitoring capabilities to improve their overall productivity. </p>
