Product overview

Measurement of rpm

Applications for speed meters are multi-faceted. In addition to rpm measurement of rotating objects, the speed or length of conveyor belts and goods sold by the metre can also be measured using contact measurement via a measuring wheel. There is also the possibility of determining the rpm of rotating objects without contact using a reflection mark and a light beam emitted by the instrument. In addition to determining rpm, stroboscopes are also frequently used for the measurement, checking and monitoring of vibrating and fast-moving parts in industrial production, due to their fast flash light sequence.

Measuring light conditions in workplaces

Daylight or the lux value in general is a crucial factor for people's well-being. Good lighting in the workplace, whether artificial or natural light, increases staff's ability to concentrate, promotes their health and reduces their complaints.

For the measurement of light conditions, Testo offers lux measuring instruments which can be used to measure the luminous intensity of natural or artificial light. The lux probe of the testo 435 multi-function measuring instrument can also determine the flicker frequency of screens which also has an influence on workplace assessment.

Measurement of sound

External Sound emissions on ventilation and air conditioning systems must be limited. The permissible limit values for sound emissions depend on the area of the building and the environment where the systems are operated. The measurement of sound also plays an important role in workplaces. If the noise level is high in the workplace, staff efficiency is reduced.

Whether for the measurement of industrial and environmental noise on ventilation and air conditioning systems or for the measurement of sound in workplaces - our portable sound level meters are ideally suited for volume measurement.
