Determine the calcium & magnesium in water samples for aquarium and aquaculture

Specification:

 Range

Ca 20 – 400 ppm as Ca Mg 12 – 960 ppm as Mg

 Resolution

Ca 20.0 ppm per drop Mg 12.15 ppm per drop

 Number of test

 120 test

 Method

 Titration method

 Component in package

1 bottle for reagent #1 – reagent #3, 2 bottle of  reagent #T, and 2 plastic tube

 Shelf life

 2 years

Instruction for use:    

Calcium

1.    Rinse the test vessel several times with the water to be tested and fill to the 5 ml. mark.

2.    Add 2 drops of reagent #1 and also 2 drops of reagent #2, then swirl gently. Solution will be pink color.

3.    Drop reagent #T drop by drop with swirls gently. After color change from pink to blue counts and record as A. 

Magnesium

1.    Rinse the test vessel several times with the water to be tested and fill to the 2.5 ml. mark.

2.    Add 1 level spoon of powder#3 and swirl gently, the solution will be orange color.

3.    Drop reagent#T drop by drop with swirls gently and counts the total drops that change the solution color from orange to green and record as B.

Calcium = A * 20 (ppm)

Magnesium = (2B – A) * 12.15 (ppm)

Total Hardness = B * 100
