WLAN data loggers from Testo for monitoring temperature and ambient conditions

Data loggers in themselves are already a practical innovation for the monitoring of numerous measurement parameters. Uses of these small aids include measuring and documenting temperature, humidity, vibration, lux, CO₂ and CO.

The disadvantage of conventional models: they require manual readout. This is precisely where WLAN data loggers get to work. The instruments, which are also known as wireless data loggers, cordless data loggers or Cloud loggers, combine precise measuring technology with data transmission via WiFi.

WiFi data logger

A Testo WLAN data logger offers you the following

  • Large selection of instruments for all common parameters/measurement parameters
  • Wireless transmission of the readings to the Testo Cloud
  • Alarm notification via e-mail and/or SMS when there are violations of limit values

Radio data loggers, WiFi loggers and WLAN data loggers from Testo

testo Saveris data logger system

WiFi logger
  • Automated measurement of temperature and humidity
  • Comprehensive alarm notification options
  • Software for analysis and documentation

testo Saveris 2 WLAN data logger

WLAN data logger
  • Temperature and humidity values are securely stored in the loggers and the Testo Cloud
  • Flexible data access via PC or smartphone
  • Individually extendable

WiFi-Monitoring system for museums, archives etc.

Wireless data logger
  • Small dimensions and customizable housing cover
  • Measure temperature, humidity, IAQ, lux and UV
  • Individual alarm function (e-mail, SMS)
     

CO₂ monitoring and indoor air quality

Cordless datalogger
  • This is how CO₂ causes illness in rooms
  • These are the limit values
  • Measure and monitor CO₂ and IAQ

This is how cordless dataloggers, Cloud loggers, etc. work.

Wireless data loggers are connected to the Internet via WLAN and store data online in the Cloud. This has four advantages:

  1. Data from sites that are a long way apart can be managed together.
  2. Data can be viewed and analyzed at any time and from anywhere in the world.
  3. Alarm notifications are provided immediately when there are violations of limit values – even to mobile terminal devices.
  4. No software is needed. Data are accessed via a normal Internet browser.

Your advantages with the Testo Cloud at a glance

Radio data logger

All measurement data. Always available. On any device.

  • The measuring values are stored in duplicate: in the data logger and in the Cloud.
  • Your data are secure, even when there is a power outage.
  • Easy data access from anywhere in the world via smartphone, tablet, laptop or PC.
  • No software installation required: you just need a normal Internet browser to view, manage and analyze your data.
  • Comprehensive alarm notification options directly to the terminal device of your choice (e-mail, SMS).

Other data loggers

In addition to the data loggers with an Internet connection (also called Cloud loggers) which we already know about, there are of course many more data loggers for a really wide variety of measuring tasks. These data loggers make sure that the measurement parameters which are relevant to your application are monitored securely and reliably.

Precise measuring technology in a compact format – that's what our data loggers stand for. Whatever measurement parameters you want to measure and monitor – we have the solution.

The most common models are temperature / humidity data loggers, because they record the two measurement parameters which are needed in most applications.

The tasks carried out by pressure data loggers include continuous measurement and documentation of absolute pressure. This is particularly important in the laboratory environment, where consistently constant ambient conditions are essential for the success of the work taking place there.

CO₂ data loggers measure and document the carbon dioxide content of the indoor air. If this is too high, users of the room can experience discomfort, tiredness or concentration problems. That is why these data loggers are often used in universities, nursery schools or offices.

CO data loggers can save lives. By measuring carbon monoxide, which is dangerous for human beings, and providing an alarm notification when limit values are exceeded, they fulfil an important task in boiler rooms, kitchens and bathrooms and other locations.

UV data loggers are generally used in museums, archives or galleries. They measure and monitor the incoming UV radiation, because this is harmful to light-sensitive objects. 

Shock data loggers measure and document vibrations during the transport of sensitive goods from the pharmaceutical, food, electronics or art sectors. On arrival at the destination, you can immediately see whether the vibration tolerances have been complied with or not.

Radio data monitoring system testo Saveris

The testo Saveris radio data logger system

Created for the most demanding monitoring tasks: the testo Saveris radio data logger system.

This is how it works:

Individually positionable and extendable radio data loggers measure and send temperature and humidity values to the base station (testo Saveris base). Up to 150 radio data loggers can be combined in one system.

The testo Saveris base receives data from the radio data logger, saves it and visualizes alarms.

All the data are securely stored in the system's software. Furthermore, evaluation and analysis of the measurement data are also possible here. The testo Saveris software is available in 3 versions which differ in terms of their scope of performance.
