Abstract
The present invention relates, generally, to an apparatus and method for water testing and, more particularly, to a simple dipstick type method for use in comparison with a color chart and suggested courses of action to correct deficiencies in water quality. Briefly stated, a detailed color chart is attached to the side of a container having a plurality of dipsticks contained therein. Each dipstick has disposed thereon a plurality of pads, the total number corresponding to the number of characteristics of the water to be tested. Additionally disclosed is a course of corrective action which may be undertaken by the unskilled user thereby greatly simplifying the process by reducing it to its simplest factors.
Claims12
A method of testing for a plurality of contaminants in water, comprising the steps of:
- (a) providing an elongated test strip having thereon a plurality of reagent test pads along its length, each test pad containing a reagent responsive to a different contaminant in water and indicating a concentration of its respective contaminant by its color characteristic;
- (b) immersing the test strip and the reagent test pads into the water for a period of time;
- (c) removing the test strip from the water;
- (d) providing a comparison chart having thereon a vertical outline of said test strip utilized to indicate the orientation of the test strip with respect to the comparison chart and a plurality of standard value rows,
- each of said rows having at least one colored standard area, all of said areas in each row corresponding to a color characteristic for different concentration standards of the same respective contaminant in water;
- and
- a concentration indicator associated with each area for quantitatively indicating the concentration standard of the respective contaminant;
- wherein the vertical outline and rows are arranged so that upon positioning of the test strip on the vertical outline each test pad substantially aligns with a test row, each test row corresponding to the concentration standards for the respective contaminant it is aligned with, thereby facilitating test comparisons between the respective test pad and color area;
- (e) positioning the test strip on the vertical outline of the comparison chart;
- (f) comparing each of the test pads with its associated test row to substantially match the color of the respective test pad with one of the color test areas of the respective associated row, the concentration indicator associated with the area indicating the measured concentration of the respective contaminant substance in the water.
A kit for testing for a plurality of contaminants in water comprising:
- (a) an elongated test strip having thereon a plurality of reagent test pads along its length, each test pad containing a reagent responsive to a different contaminant in the water and indicating a concentration of its respective contaminant by its color characteristics;
- (b) providing a comparison chart having thereon a vertical outline of said test strip utilized to indicate the orientation of the test strip with respect to the comparison chart and a plurality of standard value rows,
- each of said rows having at least one colored standard area, all of said areas in each row corresponding to a color characteristic for different concentration standards of the same respective contaminant in water;
- and
- a concentration indicator associated with each area for quantitatively indicating the respective concentration standard of the respective contaminant;
- wherein the vertical outline and rows are arranged so that upon positioning of the test strip on the vertical outline each test pad substantially aligns with a standard row, each standard row corresponding to the concentration standards of the respective contaminant of the pad it is aligned with, thereby facilitating test comparisons between the respective test pad and color area.
