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.
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?

Ideal data loggers for every application
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.
The accuracy of the measurements has a role to play for the instrument when you only have small margins in terms of the values. When goods are easily perishable or very sensitive, instruments must measure considerably more accurately than when controlling office areas. The service life of the rechargeable battery is also an important aspect. Data storage should also still be ensured even when the instrument no longer has a power supply.
A complete data monitoring system is a particularly practical option. It is designed so that the data are transmitted directly to a terminal device. That gives it various advantages:
precise checking of values
time and cost savings
transmission of data by radio or also via Ethernet
acoustic alarm if the values are exceeded
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
Detailed measurement results
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:
The USB datalogger is very popular to use, because in most cases it can be quickly recharged and it provides optimum measurement data security. This form of data logger also already has a calibration certificate and a configuration file. This makes it possible to generate the data directly on a terminal device in a PDF file and then to print this out. The analysis can then be done straight away. The advantages of the data logger are particularly practical
generation of PDFs on the terminal device
very flexible operating time
easy to use
already includes a configuration file
The radio data logger is another possible version. It may make sense to work with wireless LAN, particularly when you want to use data measurement to check either several areas or larger ones too. The data are transmitted to a chosen terminal device and you can keep an eye on all the areas. This means you save both time and costs.
