has completely dissolved.
(NOTE: do not handle Yes/No tablet with fingers)
4.
The final colour to be obtained for soft water is green. (Note: The shade of
green may vary.) If the colour turns red, the water is above 20 mg/l hardness,
therefore another regeneration is recommended.
5.
Rinse plastic bottle after each test has been completed.
6.
When used as above, the tablets change the colour from green to red at a
hardness of approximately 20ppm based on a sample volume of 10mls.
Other hardness test kits are available for more accurate testing eg.
Hardness Tablets
Directions:
Take a 50ml sample of water in a screw capped bottle. Add one (1)
tablet to sample, shake or crush to disintegrate. Repeat until last trace
of reddish tinge disappears. The final colour is usually blue but with
some water a greyish coloured end point is obtained.
Using 50ml sample -
Hardness ppm = (number of tablets x 40) - 20
LR (BW) Tablets
Directions:
Take a 100ml sample of water in a screw capped bottle. Add one (1)
tablet to sample, shake or crush to disintegrate. Repeat until last trace
of reddish tinge disappears. The final colour is usually blue but with
some water a greyish coloured end point is obtained.
Using 100ml sample -
Hardness ppm = (number tablets x 2) – 1
