Data loggers

In industry, but also in public buildings as well as in the private sector, it may be necessary to measure some values involving the air. In addition to temperature and humidity, the CO2 value for example also provides information about the indoor air quality. In order to ensure pleasant IAQ, you need a regular overview of the evolution of these values. This is where a logger is used.

The data logger: what the background is

There are also dataloggers which can be used to test the optimum conditions for specific products. In particular, temperature data loggers are often used. A USB data logger can ensure particularly easy handling. However, there are still further practical solutions.

If you want to purchase one or more data loggers, there are various factors that have a role to play in making a choice:

  • What values can be measured with the instrument?

  • How accurate are the measuring values?

  • Can the measurements be repeated?

  • How long is the service life of the rechargeable battery?

  • Are follow-on costs incurred while using the instrument?

  • What software goes with the instrument?

Data loggers - the reasons why they are so important

The question of whether data loggers should be integrated into a system or rooms depends on what the rooms are used for. Many people are active in schools, nursery schools and also in office areas on a daily basis. The rooms are often only very small in size. A high concentration of CO2, incorrect humidity or temperatures that are too high or too low may have a strong influence on well-being. However, if it is possible for you to check these values, you can respond quickly. A temperature and humidity data logger therefore offers you the option of detecting when the humidity is particularly high or low. You get an alarm if the temperature rises too high. This means you can create an effective ventilation plan.

Particularly in industry, the data logger takes pressure off the constant checking of temperature and gas exposure in day-to-day work. You have the possibility of providing the data recorder with limit values. When buying the instrument, make sure that it gives you an acoustic warning when the limit values are exceeded. That may for instance be particularly important for a cold chain.

Data recorder: the different versions

There are different data logger designs. Use of the data logger for temperature measurements is particularly well-known and frequent. However, there are also other versions which it may make sense to use. One of these is the CO2 data logger. It is able to measure the gas concentration in the air. The CO2 data logger can be of particular interest in areas where many people work, or also learn, in a small space. It indicates when it is sensible to ventilate the rooms.

It indicates when it is sensible to ventilate the rooms. UV intensity can have an influence on quality, in particular when storing goods, for example in logistics. Measurement is possible using a UV data logger which can be fitted in the rooms. Just like UV intensity, impacts and vibrations can also lead to damage, for instance during transport.

  • The shock data logger can provide information about these activities in this area.

  • It may make sense to use multiple data loggers

  • Measurements of temperature, CO2 concentration or shocks are possible

The data logger's data transmission

You will find different data loggers at Testo, which means you can ensure the areas where you want to carry out measurements are equipped in the best possible way. The focus here should be on accurate measurement results, which are important for data analysis. The question of how the data can be transmitted for analysis is also an interesting one. The security of the data and the repeatability of the measurements are an important factor too. There are two different versions when it comes to data transmission and using the instruments:
