توان تجهیز دنا، تامین کننده ابزار دقیق و تجهیزات نفت، گاز و پتروشیمی
You can carry out completely damage-free tests on materials and components with the thermal imager testo 875-1. This allows you to visualize problems in industrial maintenance and production monitoring before a malfunction or a fire risk occurs. With the testo 875-1, you are on the trail of energy loss in building thermography, helping your customers to save expensive heating costs. You therefore save time, energy and money in industrial thermography as well as in building thermography, and ensure more security allround.
