Economical turbidimeter (SGZ-A)
Principle of the instrument:
The basic principle of the instrument is that after the measuring device is put into the sample, the beam emitted by the light source forms scattered light when it meets the suspended particles, and the turbidity signal of the 90° scattered light generated is received by the photosensitive element, and the optical signal is amplified by the circuit and the data processing of a single chip microcomputer shows the measured turbidity value.
Instrument features:
1. LCD with backlight LCD display, so that the reading is more comfortable, and not affected by natural light.
2. Simple operation, appropriate measurement range and high cost performance, more suitable for various industries.
3. Unique positioning structure and high-precision optical path system effectively ensure the accuracy and repeatability of the measured value.
4. The use of low drift, high precision, good stability of the circuit system, and efficient long life light source, can effectively ensure the long-term stable operation of the instrument.
5. Users can choose different turbidity units according to their needs.
Working condition
1. Ambient temperature (0 ~ 40) ºC;
2. Relative humidity is not more than 80% RH;
3. Power supply voltage (220±22) V, (50±1) Hz
4. The instrument should be placed horizontally on a stable test bench, and there is no strong vibration source.
