testo 835 – fast, accurate

infrared measuring instruments

for trade and industry

Take advantage of the benefits the testo 835 series has

to offer, in virtually all sectors of trade and industry: e.g.

monitoring wall temperature and humidity, inspecting air

conditioning and ventilation systems, the maintenance

of industrial systems or the quality control of industrially

manufactured products.

Testo infrared measuring technology, which delivers

first-class results even at long distance, is particularly

helpful when monitoring the temperature of objects that

are small, moving, difficult to access or extremely hot.

The many features increase the room for manoeuvre, for

example in the building trade when carrying out surface

moisture measurement via infrared, or in the metal, glass

and ceramics industry when measuring temperatures up to

1500 °C. So you can be certain of having everything under

control and of safeguarding your standards of quality at all

times.
