Data Loggers & Monitoring

There are many advantages to using wireless data loggers to monitor temperatures: they save time, increase the reliability of recordings and make data more organised.

Temperature data loggers are used by food and medical industries to continuously monitor systems such as the transportation and storage of cold food, medicines and vaccinations. This helps to comply with health and safety legislation, like HACCP.

Humidity loggers help HVAC and manufacturing industries monitor air quality, ensuring effective heating and cooling systems and optimum storage of moisture-sensitive materials like paper.

ETI's temperature and humidity data loggers enable accurate monitoring, with USB and Wi-Fi options available. All our loggers are compatible with free, user-friendly software and have large memories and long battery lives for hassle-free monitoring.
