Fast, Reliable, High-Precision
Illuminance and light distribution have a crucial influence on factors such as performance and occupational safety. With a Testo lux meter, you ensure optimum interior light conditions. Typical fields of application for routine light measurement with a Testo lux meter are as follows:
- Illumination in the workplace and in public buildings.
- Light distribution in exhibitions and museums.
- Lighting for machines on production lines.
Measuring Lux with the Photometer
The luminous power (unit: lumen) between a light source and the area illuminated by it is measured using the lux (lx) unit. The illuminance is exactly one lux when luminous power of one lumen (lm) uniformly illuminates an area of one square metre. A lux measuring instrument is referred to as a lux meter or also as a photometer.

Measure Light Intensity in the Workplace
What You Should Know About Lux Meters
The eyes are a human being’s most important sensory organ. We take in more than 80 percent of information via the eyes. So, the darker the environment is, the more difficult it is for us to take in information.
This is why good light conditions are important, so that the eyes can carry out visual tasks effortlessly and reliably, but also for avoiding harm to health and hazards.
A Testo lux meter means you can be sure to achieve high-precision compliance with legal standards and limit values for illumination in the workplace. This above all involves workplaces such as assembly shops, operating theatres, PC workstations, galleries and museums, and public libraries.
Lux meters should fulfill specific criteria to measure the light intensity and light conditions reliably and precisely:
Sound level measurement allows the volume of noises to be assessed objectively. With a Testo sound level meter, you also have the ideal instrument for high-precision noise level measurement. This also means you can introduce the appropriate measures to reduce noise emissions based on the correct readings.
Sound Level Meter Features:
- Set time weighting: press the SLOW key for noises whose signal only changes slowly in terms of volume (1 s). For noises with sudden sound level changes (125 ms), press the FAST key.
- Select frequency weighting A/C: for standard sound level measurements, press the A key on your noise meter. Press the C key to assess the low-frequency component of a noise.
- Align microphone: make sure that the microphone is directed toward the sound source.
