Main features:
1) Three image display modes: full infrared, full visible, and picture in picture
It can be switched with one click, making it easier to compare and quickly locate problem areas and points.
2) Electric focusing function
In addition to manually adjusting the focal length, considering the safety and convenience of outdoor operators, The testo 881-1 has designed an electric focus key that can be operated with one hand, which can be adjusted with just the index finger.
3) Surface critical dew point (humidity) distribution
By inputting the temperature and humidity of the measurement environment, the instrument automatically monitors the surface critical dew point distribution of the measured object, such as the wall surface, to warn of the possibility of mold growth.
4) Recording function
Built in recording component, which can record images in real-time, annotate voice recordings, and save them together with the captured images for easy post analysis and search.
5) Isothermal zone display
The isothermal display range and color can be set, and the areas within the set range will be displayed in the same color.
6) The instrument provides clearer images
-High thermal sensitivity (NETD<0.08 ℃), can clearly display temperature differences as small as 0.08 ℃;
-A field of view angle of 32 ° * 23 ° displays the measured volume of the object with a larger field of view.
7) Instrument tree management mode
It can easily summarize image files, making it easy to search and manage.
8) Automatic positioning of hot and cold spots and center points
Make the high and low temperature points of the object have no escape, and the problem area is clear at a glance.
9) Tested for dust and water resistance
Meets the IP54 standard and is suitable for various harsh industrial environments.
10) Convenient data analysis and processing software
-Professional analysis report;
-The instrument kit includes a professional version of IR software for analysis and reporting, which can assist you in viewing analysis images and data, and generate professional test reports according to your requirements.
