Measurement procedure

1.Sample approximately 100 ml of water with a dry,clean beaker.

2.Snap off the tip of a fresh detector tube using the tip breaker in the tube.

3.Immerse the filled end of the tube into the sample water. Capillary action occurs and the sample water instantly rises through the reagent. If the sample contains sulphide ion, the white reagent in the tube changes to brown.

4.When the sample water rises up to the top end plug,remove the tube.

5.Read the concentration at the interface of the stained-to unstained reagent.

6.If the stain exceeds the highest calibration mark (100 ppm),dilute the sample with pure water and re-test using a fresh tube.Obtain the correct concentration by multiplying the tube reading with the dilute ratio.

Attention: Different detector tubes have different methods of use, and you need to use different test methods according to the product model you choose.
