Product information "DUROGNOST® SR 0 (0.1 / 0.05 °dH) limit value test kit"
Durognost SR 0 (0.1/0.05 °dH) Threshold test kit for the rapid determination of residual hardness.
Threshold monitoring in the very low hardness rangeSpecial liquid indicator in a dropper bottle for monitoring the residual hardness of softened water, calibrated to the limit values of 0.1 and 0.05 °dH (1.79 and 0.89 ppm). Complete with measuring tubes and stoppers. Sufficient for approximately 250 analyses; the required measurement time is approx. 30 seconds.
Identification of the hardness range
When the indicator comes into contact with the water sample, it changes colour as soon as the specified limit values of 0.1 °dH or 0.05 °dH are reached or exceeded.
How should the reagent be used?
Please rinse the supplied measuring tube with the water sample. Then fill the measuring tube with the water sample up to the 5 ml or 10 ml mark. Add one drop of indicator and swirl the tube to dissolve it completely in the water sample. After a reaction time of approximately 30 seconds, the water sample will change colour.
Water sample changes colour:
Green = softened water is fine (within the defined range)
Red = Regenerate the water softener
Please read the supplied instructions for use before use.
