Data Loggers


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 reliability 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, process, or for research purposes in the following industries

food processing





museums & archives



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 life cycle 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

Traceable certificates of calibration are available for most of the Data Loggers available on our site (BRC standards require calibration of all measuring and monitoring devices to be traceable back to a nationally recognised standard).  .

Each certificate indicates deviations from standards at three temperature or humidity check points.
