TURB-2A Precise Nephelometer

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
