ETI has used its vast experience in temperature measurement, together with the latest technology, to create the ThermaData range of small, cost-effective data loggers. Unlike many loggers on the market today, they have been designed for ease of use and with relability very much in mind.

what are data-loggers?
Data-loggers are electronic devices that record temperature over a period of time for analysis at a later date. The user chooses what information is required and the data-logger records it. The data-loggers incorporate a thermistor sensor that measures the temperature, and the data-loggers internal microprocessor chip then stores the data. The stored data can then be transferred to a computer, via a USB cradle, for further analysis at a time convenient to the user.

applications for data-loggers
There are many uses for data-loggers, for example, to ensure compliance with legislation, to help save costs, to ensure the quality of a product or process, or for research purposes in the following industries
● food processing
● environment
● agriculture
● logistics
● laboratories
● museums & archives
● refrigeration
● medical

The EC food industry directive suggests that organisations involved in food preparation, storage or transportation should have the ability to verify that the temperature of food has
been kept at the correct levels. This is often referred to as due diligence. Data-loggers offer organisations a method of complying with food industry legislation by offering traceability from the moment the food is received to the time it is delivered to the customer. For shippers, data-loggers can verify that conditions within the transportation

vehicles have been maintained within the specified levels.

For growers of fresh produce, data-loggers provide an accurate record of temperatures during the lifecycle of a product, from farm to plate, i.e. during growth, preparation and transportation of produce, thus ensuring best quality.
Monitoring the environment can help organisations ensure that HVAC systems are used to the optimum, keeping energy use to a minimum and saving money.

UKAS Certificates of Calibration
ETI's in-house UKAS calibration laboratory offers certification for both temperature and humidity data-loggers. Each certificate indicates deviations from standards at five temperature or humidity check points.
