Matters needing attention:

WGZ series of scattered light turbidity meter is a combination of precision measuring instruments, before the operation should carefully read the instructions and through the correct operation can obtain accurate measurement results.

1, the use of the environment must accord with the working conditions.

2, measuring tank must be long time clean and dry, without dust, not to be covered with a shading cover.

3, humid climate, must be extended accordingly boot time.

4, the solution to be measured along the sample bottle should be carefully pour, prevent the generation of bubbles, influence the measurement accuracy.

5, replacing the specimen bottle or repair shall be calibrated again.

6, a professional repair engineer, do not open the instrument repair.

 

Working conditions:

1, temperature 5~ 35 ℃;

2, relative humidity of not more than 80%;

3, the power supply voltage 220V ±22V 50± 0.5Hz frequency, and has the good grounding.

4, the instrument should be placed horizontally in a smooth test bench, effectively avoid direct light;

In 5, around the tool should have sufficient space to facilitate heat dissipation, and no strong vibration source and strong magnetic field interference;

Around 6, the air should be no dust and corrosive gas.
