Note:
The turbidimeter is a combination of photoelectric accurate measuring instruments, the instructions should be read carefully before operation, and corrective measures should be taken to obtain accurate results.
1. Must meet the environmental working conditions.
2. The measuring cell must be and dry for a long time, and the shielding cover must not be covered with dust when not in use.
3. In humid climates, the startup time must be extended.
4. The test solution should be carefully poured along the sample bottle to prevent air bubbles from affecting the measurement accuracy.
5. Recalibrate after changing vials or repairs.
6. Non professional maintenance engineers, please do not open the instrument for maintenance.
Working conditions:
1. The instrument should be placed in a dry room at a temperature of 5°C‑35°C.
2. When using, it should be placed on a flat work surfaces and avoid vibration.
3. Indoor lighting should not be too strong, and avoid direct sunlight.
4. Try to stay away from high‑ magnetic fields, electric fields and electrical equipment that generates high frequency waves.
5. Avoid high temperature close to the instrument.
6. Power supply to the instrument: 220V±22V, 50±1Hz, and must be equipped with a good ground wire.
