New design drinking water and swimming pool water quality analysis kit / water quality analyzer test kit

1. Press the "ON/OFF" button to turn on the instrument 2. Immerse the electrode of the pH meter into the solution to be tested (cannot exceed the immersion line) 3. When the pH value is stable, you can read the pH value 4. After finishing, wash with pure water electrode, press the "ON/OFF" key to turn off the meter.

Test item: detection of residual chlorine content in water Method of use: 1. Take 30ml water sample 2. Drop 3 or 4 drops of residual chlorine reagent into 20ml water sample and shake well. 3. Compare the water color with the color card to get the residual chlorine value (ppm or mg/L).

Test item: test the PH value of water How to use: 1. Take a 30ml water sample 2. Drop 3 to 4 drops of PH reagent into the water sample and shake well 3. Compare the color of the water with the color chart to get the PH value The measured water value.

Test item: used to determine the total hardness in water. Method of use: 1. Take 5ml of water sample 2. Soak 1 drop, shake well, the water color is red. Then add one more drop and shake well, if the color of the water is still red, add more drops and shake each drop until it changes color. 3. Shake until the water color changes from red to blue, and record the number of drops in the water. Calculation method: 1 drop = 1°fr

Test item: used to test the content of nitrite in water. Method of use: 1. Take 5ml water sample 2. Dip 10 drops of reagent into the water sample, shake well, wait for 5 minutes 3. According to the color of the water sample, it can be measured arrive.

Test item: used to detect whether the water has anti-oxidation function. Method of use: 1. Take 20ml water sample, soak 2-3 drops of reagent 2. Yellow indicates that the water sample has been oxidized and has no anti-oxidation function 3. Colorless indicates that the water sample has Antioxidant function.

Test item: increase the chlorine ion content in the water sample Method of use: 1. Take 20ml water sample 2. Dip 2-3 drops of residual chlorine reagent into the water sample and shake well 3. When the residual chlorine reagent cannot detect residual chlorine, it can be used Dip in 1 drop of bleach reagent. The water sample turns yellow, indicating that the residual chlorine reagent is effective.

Test item: Test whether the water contains mineral content. Method of use: 1. Take 10ml of the water sample to be tested. 2. Dip 1-2 drops of reagent into the water sample and shake well. 3. If the water sample is magenta, it indicates that it contains minerals. substances, it is blue and does not contain minerals.

Test item: used to detect weak acid and weak alkalinity of water. Method of use: 1. Take 10ml of the water sample to be tested, 2. Soak 1 drop of reagent in the water sample, shake well 3. If the water color is yellow, it is acidic (pH 6.0 -6.5 value), light yellow is weakly acidic (pH 6.5-6.9), blue is weakly alkaline (pH 7.0-7.9)

Test item: Check whether the water purifier can filter the pigment. Method of use: 1. Take a 50ml water sample 2. Dip 5 drops of reagent into the water sample and shake well 3. After being filtered by the water purifier, the color of the water sample changes from blue to blue It is blue to colorless. It shows that the water purifier can filter the pigment.

Test item: Test whether the water sample contains heavy metals. How to use: 1. Take 20ml of water sample 2. Dip 3-5 drops of reagent into the water sample and shake well 3. Red means the water sample contains heavy metals, yellow means it does not contain heavy metals.

Test item: Test whether the water sample contains calcium and magnesium ions. Method of use: 1. Take 10ml of water sample 2. Dip 1-2 drops of reagent into the water sample and shake well 3. The water sample turns purple, indicating that it contains calcium, magnesium ions Magnesium ions (with a certain hardness), blue means that the water sample does not contain calcium and magnesium ions.

Test item: Check whether the water sample is active water How to use: 1. Take 30ml water sample 2. Dip 5 drops of this reagent and stir for 3-5 seconds 3. If the water sample turns red, it is original ecological water (active water). If the water sample turns yellow, it is non-raw water (non-active water)

Test item: detection of dissolved oxygen content in water Method: 1. Take 10ml water sample, 2. Soak 5 drops of (I) reagent in the water sample, shake well, 3. Soak 5 drops of (II) reagent in the water sample, Shake well. Shake well (wait for 5 minutes), 4. Add 5 drops of reagent (III), shake well until the precipitate dissolves. (If not dissolved, add reagent until dissolved) Count drops. 5. Compare the color of the water sample with the color of the color card. The content of dissolved oxygen can be known.

Test item: Determination of total ammonia and amine salt concentration in water sample (calculated as nitrogen) Method of use: 1. Take 5ml water sample 2. Soak 5 drops of (I) reagent in the water sample and shake well 3. Soak 5 drops ( II) ) Add the reagent into the water sample, shake well 4. After standing for 5 minutes, visually compare with the standard color card from top to bottom. The color is similar, which is the content of ammonia nitrogen in the water (mg/L)
