• For saltwater.
• 1 drop measuring solution 3 = 20 mg/l calcium.
• Colour change from pink to blue.
• Includes syringe to measure amount of water.
• The test shows the calcium level in 20-mg increments.

The JBL Calcium Test Set Ca is a quick and easy to use test to measure the calcium content of sea water.
(Recommended level in saltwater: 400-440 mg/l calcium

NOTE: Always hold the dropper pointing vertically downwards when taking drops from drop bottle. Exterior surface of dropper should be dry. Avoid bubbles.

Swill out the measuring beaker several times with the water to be tested.
Fill the measuring beaker to the 5 ml mark with the water to be tested. Use the enclosed syringe for exact results.
Add 5 drops of reagent 1and agitate to mix. The test result is not affected by any clouding which may occur.
Add 1 small measuring spoonful of reagent 2 (narrow end of the enclosed double-ended spoon) and agitate until the powder has dissolved.
Add reagent 3 one drop at a time, counting the drops, and agitate after each drop until the colour changes from pink via violet to blue. The number of drops needed multiplied by 20 gives the calcium content in mg/l. Example: 12 drops of reagent 3 = 240 mg/l.
