A data logger, also known as data recorder is basically an electronic accessory that documents data with respect to time or to location either with an inherent instrument or via sensors. Progressively, but not absolutely, they are emanated from a data processor or computer. They are usually small in size with portable battery power. Data loggers are used in environmental testing of parameters such as temperature, humidity, wind movement, precipitation etc.

A temperature logger is a thermometer with memory. It tells you what the temperature is, what the temperature was. It can tell you when everything is in normal as well as when the temperature reaches excessive level. In addition, it will tell you how long it stayed at that particular temperature. Temperature loggers self-operate record keeping, they are automated and save you a lot of time, money and reputation. They are simple and easy to use and humans can adequately avoid mishandling in data by using it.

Classification

Instrument Devices are one Australian based company that is offering following Temperature Data Loggers at a very feasible cost without compromising precision and durability:

1. USB Air Temperature, Relative Humidity, Air (Atmospheric) Pressure Data Logger-3 In 1
2. USB Air Temperature Data Logger
3. Temperature & Humidity Data Logger
4. Air Temperature, Relative Humidity, Dew Point Data Logger
5. 4 In 1 Air Temperature, Humidity, Dew Point, Heat Index Data Logger
6. 2 Channels Universal Thermocouple Thermometer Data Logger

Before you can use these data loggers you need to download the software. The data could be consequently achieved by the user in Excel and text formats. These type of data loggers assemble data periodically at computed intervals and pass on through wired or wireless connection to a consolidated server or to an internet-based server. The data can be viewed over the internet. There is also a set-up of limits of different parameters and if they exceed the set parameters at that instant alarm would be alerted. These instruments possess high contrast LCD display for time, date, current measurements, minimum or maximum measurements with low battery indicator. Download of logged data is easy, just connect the USB Cable to the instrument and computer, open the software and click download. Through raw data, this device is also able to bring up graphs and summary for the given readings with respect to time.

Applications

Temperature data loggers can ideally be used for various applications in different industries and fields such as in industrial / production fields, food processing industry, hospitals, pharmaceutical storage and transport, weather stations, temperature sensitive commodities, site evaluation, record keeping,  and other automated businesses. If you have medicine box full of vaccines and want to check the temperature inside the box, in this case, temperature data logger will help you in monitoring temperature. At the same time, since USB data logger has water-resistant property so it has been widely used in maintaining the temperature of aquariums, water tanks and water-based breeding houses.

Thereupon, the data collected from temperature data loggers can be further used to discover historical conduct, to readjust and calibrate, as a part of an R&D program to delve into the latest designs for fixtures or production steps.
