|---|---|
| Total Chlorine Range | 0.00 to 5.00 mg/L |
| Total Hardness Range | 0.00 to 4.70 mg/L |
| pH Resolution | 0.1 pH |
| Operating Temperature | 0 to 50°C (32 to 122°F) |
| Battery Type | 1x9 volt |
It adapts the USEPA method and Standard Method 4500-G, causing a pink tint in the sample upon reaction.
It adapts the TPTZ method, where the reaction between iron and the reagent causes a violet tint in the sample.
