HI38904 Pool Line Quick Total Hardness (TH) Chemical Test Kit is a basic test for the measurement of total hardness, as CaCO3, in swimming pools, hot tubs, and spas.
Hardness is an important measurement since if the levels are high the calcium carbonate is likely to precipitate, especially as the pH increases, will lead to cloudy water, clogged filters, and heater inefficiency. If hardness is low then the pool water will attack with calcium carbonate (lime) that is used in grout and concrete leading to pitting and etching.
The HI38904 is a titration-based chemical test kit that determines the total hardness concentration within the 0 to 800 ppm (mg/L) range. The HI38904 is supplied with all of the necessary reagents and equipment to perform the analysis for total hardness.
| Hardness Level | ℉H | °dH | ppm (mg/L) |
|---|---|---|---|
| Very Soft | 0 – 7 | 0 – 4 | 0 – 70 |
| Soft | 7 – 15 | 4 – 8 | 70 – 150 |
| Slightly Hard | 15 – 25 | 8 – 14 | 150 – 250 |
| Medium Hard | 25-32 | 14 – 18 | 250 – 320 |
| Hard | 32 – 42 | 18 – 23 | 320 – 420 |
| Very Hard | >42 | >23 | >420 |
1 TH = 1 ℉H = 0.562 °dH = 0.2 meq/L = 10 ppm (mg/L) CaCO3
