Bluetooth thermometer

Small measuring devices for a wide range of tasks

Bluetooth thermometer

The perception of temperature is always subjective and cannot be determined to the exact degree. Without a thermometer, it is impossible to know precisely whether certain limit values are still being maintained or have already been exceeded. In many situations, regularly checking a thermometer is also not feasible. For these cases, Bluetooth thermometers are ideal, as they automatically record the necessary data and transmit it to a smartphone. Using the associated app, the data can be evaluated, and long-term comparisons and analyses can be generated..

Bluetooth thermometers are used in the following areas, among others:

  • Food transportation: Checking the cold chain

  • Deliveries of refrigerated products: Measurement of incoming goods temperature

  • Food storage: Temperature control during storage in counters or cold rooms

  • Temperature measurement for chemical solutions

For smart temperature, humidity, flow and pressure measurement

Smartphone thermometer: Modern temperature measurement via app

Laboriously writing down the values measured using a thermometer is a thing of the past. Thanks to the latest technology, users can now rely on the Bluetooth thermometer, which is used in conjunction with a smartphone. This new measuring device is ideal for measuring temperatures in ducts or other outlets through which air flows. Ambient temperatures can also be measured with the smartphone thermometer. The modern measurement technology of the Bluetooth thermometer is characterized by the highest accuracy and the possibility of transmission to the smartphone. With the help of the app for Bluetooth thermometers provided by Testo, the measured values can not only be read but also evaluated.

The display of the Bluetooth thermometer values in a table or optionally in a diagram is helpful for this. This makes short, medium and long-term changes directly visible. Users can also use the log function, which can then be converted into an Excel or PDF file. This also makes it easy to send the data from the Bluetooth thermometers. It is important that the required system requirements are met: Android. 6 or iOS 10 should be available. The Bluetooth 4.0 format must also be supported.

Bluetooth measuring devices: Bluetooth thermometers and more

Testo offers different Bluetooth measuring devices for every application in industry, trade and commerce. In addition to measuring the temperature with the support of a smartphone, modern humidity meters measure the humidity in rooms and gases as well as gas mixtures. The humidity can be determined directly via the measuring device, which in turn sends its data, like the Bluetooth thermometer, to the tablet or phone on which the corresponding app has been installed. These devices are the new standard and have long since replaced infrared as the wireless version. With all these devices, the above-mentioned advantages of Bluetooth thermometers and the use of an app are evident: evaluating the measured data from the Bluetooth thermometer is child's play. These can be incorporated into further evaluations or sent to other employees and project participants.

iPhone thermometer: Mobile temperature measurement

The testo Smart app is available for Android and iOS. The practical measurement menus turn the smartphone or tablet into a mobile measurement center and make work much more efficient. In addition, various measurement values can be displayed simultaneously and changes in the measurement values are immediately visible. The advantages of Bluetooth thermometers for smartphones or tablets include:

  • Display of up to six smart probes

  • Readings can be taken from a distance

  • Automatic calculation of various parameters

  • Image documentation and insertion of comments possible

  • Pre-set menus available
