Testo 868 thermal imager

The Testo 868 thermal imager is another step in detecting images that provide information on the temperature of remote surfaces. It has several advantages over previous models in both image resolution and performance.

These types of instruments are very useful in building inspection. In addition, they help in the supervision of production processes and quality control and offer preventive maintenance measures for machinery.

The Testo 868 Thermal Imager is a robust and easy-to-operate camera that has been designed to offer remarkable versatility. It incorporates a digital camera that allows real images to be obtained together with infrared.

Another highlight of this camera is its connectivity. It has a Wi-Fi connection that makes possible a quick, comfortable and easy exchange of images through its application. In this way, the images taken on the smartphone or tablet can be made as easy as possible. To make use of this function, it is only necessary to install the application on the mobile device.
The power supply takes place through the use of a rechargeable battery, which gives it a very interesting autonomy. The battery is 2500 mAh lithium ion that offers a use of the equipment around 4 hours. It can also be powered by the mains supply included in the set. The camera can be connected via USB to a computer, thus allowing battery charging. In the event of a power failure during the battery change, the camera has a backup battery that allows the system data not to be lost.

By powering, using the power supply, recharging can take up to five hours, whereas if this action takes place using the computer's USB interface, recharging can take approximately eight hours.

The Testo 868 has the SuperResolution technology that allows to improve the image quality. In this way, a sequence of images saved in the camera can be converted to a resolution 1.6 times higher, by creating images with four times more measurement values without interpolation. In this way, it is possible to go from an infrared resolution of 160 x 120 to 320 x 240. The measurement range is -30 ºC to 650 ºC, making it very useful for a wide variety of diverse applications.
The images taken are saved in BMT format containing all the temperature data. They can also be saved in JPEG format, but in this case the temperature data is not obtained. The camera has an internal memory of 2.8 GB and is capable of storing more than 2000 images, offering a very interesting autonomy for the user.

The camera has correction parameters that make it possible to correct certain environmental conditions, such as high ambient humidity or a great distance from the object to be measured.

It has various measurement functions. Thus, it is possible to carry out single point, "coldspot" or cold point, "hotspot" or hot point, differential temperature, "scaleAssit" or "IFOV Warner" measurements.
