The characteristics and application range of illuminance meter
A lux meter (or lux meter) is an instrument that measures illuminance. It is to measure the degree to which the object is illuminated, that is, the ratio of the luminous flux obtained on the surface of the object to the illuminated area. The illuminance meter is usually composed of a selenium photocell or a silicon photocell with a filter and a microammeter.
Let's take a look at the functional characteristics of the illuminance meter
1. Track and record the change of illuminance throughout the whole process, with a long recording time (data can be recorded once every 15 minutes, and can be recorded for up to 5 months or even longer), integrating data collection, recording and transmission.
2. The power consumption of the whole machine is small, using a lithium battery (built-in) for power supply, and the battery life can reach more than one year.
3. There are two versions of the software, Chinese and English, which can be chosen arbitrarily, and the English version has international versatility.
4. The software is powerful and easy to view data.
5. Automatically generate record curves, and the collected data can be processed by EXCEL, WORD or software.
6. The recording time interval can be set arbitrarily from 2 seconds to 24 hours.
7. Small size (58×72×29mm), simple operation, reliable performance (suitable for harsh environments, no data loss when power is off).
8. It can alarm automatically.
Application range
1. General public place application
In order to ensure that people can live under suitable light, our country has formulated health standards for indoor (including public places) illuminance, and uses illuminometers to measure the illuminance of various places.
2. Lighting production industry, photography industry, stage lighting layout, etc.
The illuminance meter has been successfully applied to many projects, such as lighting production industry, photography industry, stage lighting layout, etc. Different models of illuminance meters can meet different measurement requirements.
3. Factory production line application
In the factory, the illumination requirements on the production line are relatively strict. Continuous work will cause visual fatigue and greatly reduce work efficiency. Usually the illumination requirement is ≥1000Lx. For places with relatively high illumination requirements, a large-range illuminance meter can be selected, with a super-large range. Can deal with strong light illumination measurement.
4. The application of illuminance meters is very extensive, including the applications in our daily life, such as factories, warehouses, schools, offices, homes, street lamp construction, laboratories and so on.
