The Taylor K-1766 salt test determines sodium chloride levels, important for pools with a salt chlorine or "saltwater generator" (SWG). This kit contains all of the required pieces: R-0630 Chromate Indicator Reagent, R-0718 Silver Nitrate Reagent, a Taylor 9198 graduated cylinder, and instructions.
R-0630 is added to 10mL of pool water to produce a color change to yellow. Then, R-718 Silver Nitrate Reagent is added drop by drop to produce a color change to milky red ("salmon color"). The required number of drops is multiplied by 200 to determine salt levels in ppm.
This kit is contained in the signature blue Taylor kit box.
