Testo's line of IAQ measurement instruments help technicians ensure HVAC systems are working properly. Any inconsistencies may negatively impact the health of staff. Good control of indoor humidity, temperature and all the other variables that comprise IAQ can reduce the chances of personnel having to take sick days and improve their ability to perform daily tasks.

The indoor climate is also determined by the prevailing light conditions in the area.

Monitoring these light conditions and measuring the lux level are therefore an important part of comfort level measurement in the workplace. Almost everybody has come across this: background noises which easily prevent you from working and from concentrating on something.

If the noise level is high at work, staff efficiency is reduced - no matter whether the noise pollution is caused by equipment or colleagues. 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.
