move | Operating Instructions | caveat |
Sample collection | Samples are taken in transparent glass bottles and stored away from light | Avoid contact with metal containers to prevent decomposition of reagents |
Reagent Addition | Use pre-made reagent tubes and insert them into the corresponding test wells as prompted. | Reagents need to be refrigerated at 2-8℃ with a shelf life of 3 months. |
detection initiation | Touch screen to select the parameters, the instrument automatically complete the color development, measurement and result calculation | Rinse the colorimetric tube with deionized water before each test. |
Interpretation of results | Direct display of mg/L values on the screen | Comparison with national standard limits to generate compliance conclusions |
