Description of Tests
Analyte | System | Method/Chemistry | Standard/Equivalance or Description | Comparator | Cell |
---|---|---|---|---|---|
Hardness, Calcium | Drop test | EDTA titration (includes inhibitors to prevent metal interference) | 1 drop = 10 ppm calcium hardness as CaCO₃ | NA | 9198 |
Alkalinity, Total | Drop test | Blended indicator | 1 drop = 10 ppm total alkalinity as CaCO₃ | NA | 9198 |
Chlorine, Free & Total | Midget comparator | DPD | 0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0, 3.0 ppm chlorine (Cl₂) | 9040 | 4024 |
pH w/ acid/base demand | Midget comparator | Phenol red | 6.8, 7.0, 7.2, 7.4, 7.6, 7.8, 8.0, 8.2 | 9053 | 4024 |
Potential Interferences
Test Parameter | Description |
---|---|
Chlorine levels > approx. 10 ppm may bleach out indicator; to prevent, dilute sample with DI water as necessary and retest. Other halogens and oxidized manganese may cause positive interference. | Chlorine |
Sanitizer levels > approx. 10 ppm may cause a blue-purple color resulting in false high readings. Wait for sanitizer level to decrease to normal levels and retest to assure an accurate reading. | pH |
Shelf Life Concerns
TEST STRIP SHELF LIFE
As with all perishables, test strips are sensitive to environmental influences and will last longer under controlled conditions.
To this end, we recommend:
- Storing test strips at a consistent temperature in the range of 36°–85°F (2°–29°C); storing test strips in a refrigerator can prolong the shelf life, but the bottle must be warmed to room temperature before opening to avoid condensation.
- Keeping them out of prolonged direct sunlight.
- Segregating test strips from containers of treatment chemicals.
- Replacing bottle lids immediately to reduce exposure to air and humidity.
Taylor formulates its test strips to remain effective for two years, the only exception being Salt test strips which last one year. As a general precaution, replace all test strips more than one year old, or at the beginning of a new testing season.
