Instructions
- Remove one test strip from the amber bag, and reseal the bag as soon as possible.
- Do not touch the test pad with your fingers.
- Completely immerse the test pad into the specimen for 1-2 seconds.
- Remove and compare to the colour chart within 15 seconds.
NOTE: The pH of the water can affect the reaction of the Water Hardness test strip. The test paper is buffered to provide the optimal pH for a colour reaction, however, highly acidic water may not fall within the boundaries of this buffer. Therefore, if the water being tested is highly acidic, we recommend you alkalise the water sample to neutralise the pH before testing for hardness.
