Changes in pH, hardness, alkalinity, and chlorine can all indicate a change in water chemistry that may have resulted from a chemical spill, sewage, or algal blooms.
Benefits of teststrips
- Testing is fast, easy, and convenient
- Reduces the chance of human error associated with other tests
- No measuring samples or counting number of drops
- Require less technique
- Ensure proper handling and storage
- Store in a cool dry place
- Bottle comes with 50 test strips
pH is a measure of the acidity or alkalinity of water. It is usually measured by using a colorimetric test – test strip changes colour with increased acidity or alkalinity. pH varies naturally within streams as a result of photosynthesis. There are a number of reasons that water may have extreme pH values:
The pH scale ranges from 0 to 14:
A ph range of 6.5 – 8 is optimal for freshwater.
A range of 8 – 9 is optimal for estuarine and sea water.
Acidic 0 to 6.9
Alkaline 7.1 to 14
