使用照度計測量照度 – 它如何工作？
光源與被照射區域之間的光通量（單位：流明）是使用勒克斯（lx）為單位加以測量。當1流明（lm）的光通量均勻地照射在一平方米的面積上時，照度就是1勒克斯。照度的測量儀稱為照度計，或者稱為光度計。

Your advantages with a Testo light meter
As market leader, Testo offers high-precision, tried and tested luxmeters for light measurement.
- Compact design: the handy lux meters are particularly well suited for fast, uncomplicated measurement.
- Sensors match the spectral sensitivity of the human eye.
- Convenient measuring value readout with Hold function.
- Measurement in seconds: ideal for spot measurement in offices or retail outlets.
- Large, clear displays. In addition, maximum and minimum values can easily be displayed at the touch of a button.
Measure light intensity in the workplace: with Testo's precise sensors
Better measurement with Testo: 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
- public libraries.
Lux meters should fulfil specific criteria in order to be able to measure the light intensity and light conditions reliably and precisely:
- Sensor type: The type of sensor is important when it comes to a lux meter, because it has to perceive ambient light in a way that corresponds to the human eye. Eyes have different sensitivities to colours or wavelengths and perceive yellow and green light better than, for example, red or blue. This must also be ensured with the sensor.
- V-Lambda curve: Lux meters, which assess illuminance according to the V-Lambda curve (spectral sensitivity curve), are suitable for all common light sources.
- Operation: A lux meter with a well-structured measurement menu can be operated intuitively. This increases the efficiency and precision of the measurement, because measurement errors due to inadvertently false inputs can be avoided. Testo measuring instruments are at the cutting edge in this respect.
- Display size: Lux meters – like measuring instruments in general – should have a large display, to ensure you can read the measuring values quickly and accurately. This also helps to avoid errors when recording the measuring values. Particularly when you have to be quick.

Special lux meters and other measuring instruments from Testo
Lux meter integrated into the WiFi data logger
The first choice instrument specifically for the long-term recording of measurement data is a data logger. This means, for instance, that sensitive and valuable exhibits in museums and archives can be given outstanding protection using a WiFi data logger. An air velocity & IAQ logger with an integrated lux sensor, along with other sensors for recording temperature, humidity and UV, ensures comprehensive monitoring of the ambient conditions and illumination in museums. Convenient: functions such as data storage in the Testo Cloud and real-time alarm via e-mail.
Lux meters as external probes
Monitor light-sensitive exhibits with external lux probes. Simply connect the probe to the appropriate data logger and you can count on outstanding digital measurement certainty straight away. The measuring values are processed directly in the probe and thus even extremely long cable connections cannot impair the precision of the measuring values.
Sound level meter
A Testo sound level meter means you are extremely well equipped for the measurement of industrial and environmental noise. Discover the measuring instrument which is ideally suited to your tasks and ensures that limit values and standards within your area of responsibility are accurately adhered to.
Rpm measuring instrument
A Testo rpm measuring instrument provides you with perfect support for your tasks in air conditioning technology or industrial production. Testo offers you measuring instruments for non-contact rpm measurement via reflective marker and light beam or those with contact measurement via measuring wheel.
Our recommendations for CO₂ and CO measurement
Are you looking for measuring instruments to monitor indoor air and ambient conditions? Testo also provides you with outstanding measurement solutions for these parameters. Achieve high-precision determination of carbon dioxide in the indoor air with a CO₂ meter from the market leader. When it comes to flue gas measurement, you will best fulfil your responsibilities with a Testo CO meter. Our highly sensitive CO sensors record even the smallest concentrations of the perfidious respiratory poison, carbon monoxide, and issue acoustic and visual warnings.
