Measurement procedures:

1, zero turbidity water poured into the sample bottle to the scale line, then screw on cap, and clean the bottle water trace and fingerprints, it should be noted that the open not available when the hand directly with the bottle body, so as not to leave fingerprints, affect the accuracy of measurement.

2, will be packed with zero turbidity water sample bottle, into the sample holder, and to ensure that the specimen bottle scale line with quasi specimen holder white line of position, and then covered with a shading cover.

3, wait for stable after adjusting zero adjusting knob, so that the display is zero.

4, the same device calibration using 100NTU standard solution, and is placed in the sample holder, adjustment knob, so that the display as the standard value 100.

5, 2, 3, 4, repeat steps, to ensure zero and calibration values are correct and reliable.

6, into the sample bottle, and stable to note the water turbidity value.
