The light intensity meter is mainly used in those areas.
Light intensity measuring instrument is mainly used in those aspects Illuminance meter is a kind of automatic printing fiber optic, is the measurement of artificial light and natural light intensity of optical test instruments, it solves the problem of continuous measurement of light intensity and automatic recording. It is composed of a light detector, an automatic shift amplification circuit, a curve recording device, a digital printing device and an instantaneous digital display device, in which the curve recording device adopts the frictionless recording method of optical fiber, the light detector is composed of a filter and a Ran Silicon photocell, so that the visible spectral response curve is in line with the visual spectral curve of the human eye as stipulated by the Commission on Illumination (CIE).
The portable illuminance meter belongs to a kind of illuminance measurement technology field, which is suitable for measuring illuminance in agricultural production, daily life and outdoor traveling. It adopts a photoresistor as a photoelectric conversion device, and it contains a DC power supply, a voltage conversion circuit, a switch, a photoresistor, a test circuit, an A/D converter, a decoder, a display driver, and a display, all connected in series in sequence to the output of said DC power supply.The SO 200K Light Intensity Measuring Instrument avoids the use of a luminous head, and a DC power supply can be obtained by using a battery of only 9VBlock, and the decoder, the display driver, and the display are integrated in an integrated circuit. driver and display are integrated on an integrated circuit card, which makes it simple in structure, small in size, easy to move, and also has the advantages of sensitive response. A kind of ultraviolet radiation illuminance meter, belongs to optical test instrument. It is characterized by two one-way cut-off optical filters and two identical photoelectric receivers constitute a dual optical path detector, the circuit part of the double amplification, so as to be able to accurately measure the radiation value of the required test bands, the stray light cut-off is very strong Illuminance meter test principle: illuminance is the illuminated plane received on the light flux of the surface density. Illuminance meter is used to measure the illuminance of the illuminated surface of the instrument, is the illumination measurement in one of the instruments used more than zui.
Illuminance meter structure principle: illuminance meter by the photometric head (also known as the light probe, including the receiver, V (λ) on the filter, cosine corrector) and reading display two parts.
