Data loggers for temperature and humidity – the fields of application

Ambient data can be important and influential in different areas. When transporting or storing goods, it is necessary to keep an eye on how the ambient data evolves and thus to be able to respond quickly when major changes occur.

The data are just as important for good indoor air quality. Personal well-being also depends to no small degree on temperature and humidity.

Data loggers for temperature and humidity are capable of measuring data at defined intervals. These are then stored in an integrated data memory. This involves separate temperature data loggers and humidity data loggers, along with instruments which carry out both measurements.

The search for a suitable data logger is based on the different features the instrument needs to have:

  • type of measurement
  • combination of different ambient data
  • service life for battery or rechargeable battery
  • accuracy in terms of the measurement results
  • repetition of measurement results
  • transmission path – USB or WiFi

Climate data logger – important instrument features

The question as to which features a climate data logger should have depends on the planned field of application. If you want to use the instruments to monitor the environment around sensitive goods, a cold chain or also a transport operation, then precise measuring values are essential. If you are planning to check rooms, such as those in schools or also in offices, small discrepancies in terms of the measuring values are less serious. The accuracy of an instrument can therefore already limit your choice.

Data storage and repeatability of measurements are particularly important, regardless of the field of application. Storage should still be ensured, even when the instrument no longer has a power supply over a relatively long period of time. This is the only way to ensure the possibility of continued analysis in the future. In this context, it is also worthwhile having a look at the rechargeable battery's service life during your search. You should also check whether there is an acoustic warning telling you when the rechargeable battery needs charging.

You are under a great deal of pressure when it comes to monitoring certain areas. The measurement results must be controlled and adjusted within a short time, so that no damage to goods and products can occur. In this respect, data loggers can take the pressure off, because they measure the values accurately and warn you via acoustic signals if limits are exceeded. The transmission of data to a terminal device can work in different ways. There is for example a hygrometer data logger in the form of an instrument with USB or WiFi. The use of a climate data logger which is integrated into an overall data monitoring system is particularly effective. The complex system is designed in such a way that the data can be sent directly to a preferred terminal device and analyzed there. This naturally has some advantages which you can benefit from in terms of the moisture datalogger:

  • significant time saving thanks to easy overview
  • quick data transmission
  • setting of limit values
  • acoustic signals

Additional equipment for the climate data logger

The climate data logger is often very well equipped. There is thus the data logger for temperature, humidity and air pressure. However, it may make sense to use additional instruments in combination. The measurement of gas concentration in the rooms may therefore be sensible in some areas. CO and also CO₂ data loggers are suitable for this. In some cases, these are also available in combination with temperature measurements. Looking at exposure to UV radiation is often underestimated, but nevertheless important. UV radiation can have a lasting effect on the quality of goods and raw materials. A UV data logger enables you to keep an eye on these values. Strong impacts or also movements, as is the case with transportation, are often problematic for sensitive products. The shock data logger can record how strong the impacts have been. This enables you to estimate how great the possible damage might be.

  • There are data loggers for different ambient data
  • Display of UV exposure is possible
  • Measurement results can be compared by regular measurement

Ordering Testo humidity data loggers online

Testo's humidity data loggers can measure different types of moisture. Both material moisture and humidity can be very well monitored in this way. Here, you can choose from a variety of designs. You have the option of ordering a data logger for temperature and humidity which gives a regular overview of the evolution of the values.

There are also differences in terms of the size and design of the models. The USB temperature / humidity datalogger is just as practical as models with WiFi.
