Introduction Turbidity indicates the obstructive degree of water suspended matters when the light through them. Water contains dirt, dust, micro-organisms, plankton and other micro-organisms and colloidal substances can be turbid. Working principle: Place the sample in the cuvette and will occur 90 ° dispersion when the light through the cuvette. Through the sensor detects the intensity of scattered light and amplificatory filter, the water turbidity will be confirmed by V/F converse into frequency signal which is acceptable in single-chip computer. It’s widely used in quality testing in tap water, sewage. Features: 1. V/F conversion, digital filter technology, exellent anti-interference ability and stability. 2. The instrument store calibrated curves of the whole scales, can be used without calibration. 3. The whole measuring range were divided into four scales (0~5NTU, 5~25 NTU, 25~100 NTU, 100~400 NTU), with one-point calibration for full-scale function. 4. Using a unique turbidity calibration method to greatly improve the detection accuracy. 5. Date protection if power failure. Technical Parameter: 1. Measuring Range: 0~400 NTU. (can extend to 1000 NTU) 2. Accuracy: ≤ ±2 % (F.S) 3. Repeatability: ≤± 2 % (F.S) 4. Distinguishability: 0.01 NTU 5. Drift Per Hour: < 0.1 NTU 6. Dimensions: 282mm×237mm×102mm 7. Weight: 2.2kg 8. The Nephelometer will be continuous operation after power for half an hour under the following circumstances: (1) Operating temperature range: 0~40℃ (2) Relative Humidity: ≤ 85% (3) Power Supply: AC(220 ±10%)V; 50Hz (4) No obvious vibration and electromagnetic interference, avoid direct sunlight
