Instructions for using 16 in 1 water test strips

Sample preparation should be carried out at an ambient temperature of 2 to 30 °C and a relative humidity of up to 80.

Instructions for using test strips:

Following the points will allow you to get the most accurate result (96% accuracy).

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 1-2 seconds.
Holding the strip horizontally, gently tap or shake to remove excess water.
Within 60 seconds (too much or too little time will affect the readings) compare the result. Match the color of the reaction zone of the test strip with the color chart.

In good light, hold the test area near the chart on the bottle label. Color changes that appear at the edges of the test areas or after 2 minutes or more are not significant.

Precautionary measures when using test strips for water analysis:

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 keep the liquid being tested colorless or light. If the liquid is too dark, it can be decolorized by adsorption with activated carbon before testing. If the liquid being tested is relatively turbid, let it stand for a while and take a clean portion for testing after it settles.
