鹼度測試試劑 Salifert Kh / AIK

鹼度測試試劑

鈣並不是唯一形成珊瑚骨骼並使藻類生長的物質。還需要碳酸鹽和碳酸氫鹽，而這兩種物質可以在 8.1 到 8.4 的範圍內對穩定或緩沖水族箱中的 pH 值產生重大影響。

• Salifert  Kh / AIK鹼度試劑足以進行 100 到 200 次測試。
• 可用於海水、淡水和花園池塘水
• Salifert KH/鹼度試劑可以檢測鹼度水平的微小變化，以 0.1 meq/L 進行測量，並能測試出顏色的變化。

使用方法:

1. 使用注射管取4ml的缸內水至測試瓶中(低準度或是要節省用量，請加入2ml)
2. 請先搖晃KH-Ind測試液，再加入4滴的KH-Ind(低準度測法請滴入2滴)
3. 將紅色針頭裝在1ml注射管上，確定針頭浸入KH試劑中，使用注射管取1ml的測試液。
4. 黑色活塞的下緣需達到1ml，活塞下方會有一段的空氣(針筒和針頭間的空隙)不會影響結果
5. 緩慢地將試劑滴入測試瓶，每次請先滴入1-2滴，搖晃均勻後，直到顏色從藍/綠色轉變到橘紅/粉紅色(小提示：如果你大概知道需要多少量的試劑，可先加入約80%試劑，均勻搖晃10秒，再慢慢滴入直到顏色轉變)
6. 將針頭朝上，閱讀注射筒上的刻度(黑色活塞的上緣)，並對照數值表即可得出KH數值。

低準度測法，請將數值乘以2。
＊天然海水的KH值為7-8dKH或2.5-2.9meq/L

Salifert  Kh / AIK

Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow. Carbonate and bicarbonate are also needed and these two substances can have a major effect on stabilising or buffering pH levels in the aquarium in the correct range of 8.1 to 8.4.

• The kit is Sufficient for 100 to 200 tests
• Can be used for marine water, freshwater and garden pond water
• The Salifert test is sensitive enough to detect small changes in levels of alkalinity, measuring in steps of 0.1 meq/L and demonstrating a very sharp color change.

Instruction:

1. Add with the 5 ml syringe 4 ml of water in the test vial. For a lower resolution and more tests per kit add 2 instead of 4 ml.
2. Shake the KH-Ind dropping bottle a few times and add 2 drops in the test vial (1 drop for the low resolution mode).
3. Put the plastic tip firmly on the 1 ml syringe. And draw into the syringe the KH reagent (ensure that the end of the plastic tip is constantly submersed in the KH reagent) till the lower end of the black part of the piston is exactly at the 1.00 ml mark. There will be some air present just below the piston. This is the air which was present between the end of the plastic tip and the piston. This will not influence the test result.
4. Add dropwise with the 1 ml syringe the KH reagent to the water in the test tube. Swirl after each drop a second or two. Continue with this until the color changes from blue/green to orange-red or pink color (whichever color is observed first).
5. Hold the syringe with the tip facing upward and read the position of the, now the upper end, of the black part of the piston. The syringe has graduations of 0.01 ml. Read the KH or alkalinity value from the table or calculate as follows.
6. KH in dKH = (1 – reading in step 5) x 16Alk in meq/L = (1 – reading in step 5) x 5.71

If you have chosen for the lower resolution multiply the calculated result by 2.

Natural sea water has a KH of 8 dKH or alkalinity of 2.9 meq/L
