Indicator test strips for water analysis in swimming pools, saunas, spas, aquariums, drinking, tap, waste and other water for both qualitative analysis and semi-qualitative analysis by 6 parameters.
Instructions for preparation
Sample preparation should be carried out at an ambient temperature of 2 to 30 °C and a relative humidity of up to 80 °C.
Instructions for use
Compliance with the points will allow you to obtain the most accurate result (accuracy 96%).
- At room temperature of approximately 25°C, collect a water sample for analysis in a vial, cup or container (5-10 ml).
- Immerse the test strip in the water sample for 2-5 seconds.
- Holding the strip horizontally, gently tap or shake to remove excess water.
- Hold the strip in the air for 10-15 seconds (too much or too little time will affect the reading).
- In good light, hold the test area against the chart on the bottle label.
- Compare the color of the test strip reaction zone with the color chart (color changes that appear at the edges of the test areas or after 2 minutes or more are not significant).
Precautions when using water test strips:
- Avoid touching areas containing reagents to avoid contaminating the test paper and affecting the test results.
- After removing the required number of test sheets, keep the remaining test sheets covered and protected from light.
- Try to make sure that the liquid you are testing is colorless or light in color.
- Before testing, too dark colored liquid can be decolorized by adsorption with activated carbon.
- If the liquid being tested is relatively cloudy, let it stand for a while and take a clear portion for testing after it settles.
