What is a data logger?
A data logger is an electronic device that records data over time or distance. TME supplies several different temperature data loggers for different uses. Most temperature data loggers are small, battery powered and use a microprocessor, internal memory, and an external or internal temperature sensor. Some dataloggers can send data in realtime, using WiFi, and some can download easily to a computer using an induction pad or wired connection. All of the data loggers that TME supplies can be sold with their own software. Some of the TME data loggers have digital displays, and some can come with built in alarms for out-of-range temperatures. The benefit of using a data logger for temperature is that it collects data on its’ own, with no need to carry out spot checks etc. This means that you can keep a constant log in changes to temperature, which can be very useful for some applications, including transport. However, data logging thermometers tend to be quite expensive, especially with the added cost of software, and do not allow you to record information about specific items/products, as you would need to for spot checks, so it’s worth thinking hard before you decide whether or not to buy a data logger or a normal thermometer.
