Patent number: 10527599Abstract: A kit for determining if a shock treatment is required for a water source may comprise a test strip having at least two chemically treated test areas. One of the areas is responsive in color to a concentration of free chlorine in the water and another test area is responsive in color to a concentration of total chlorine in the water. A chlorine indicator scale may be provided on a substrate, such as a label, and comprises a plurality of pairs of colored indicia and each pair of colored indicia representing a color pattern indicating a concentration, or range of concentrations, of total chlorine and free chlorine in the water. An alphanumeric designation may be provided adjacent to each pair of indicia indicating whether a shock treatment is required for the water source based on a color pattern the associated indicia pattern.Type: GrantFiled: January 14, 2014Date of Patent: January 7, 2020Assignee: HACH COMPANYInventors: Teresa Lynn Swanson, Ronald P. Merwin

Patent number: 9545781Abstract: A test element (10) used to determine concentration levels of free and total chlorine in a water sample comprises a test pad (12) adhered to a substrate (14), wherein the test pad (12) is impregnated with a stabilized DPD solution. The test pad (12) is color responsive to different concentration levels of chlorine in the water and compared to a color chart to determine the level of free chlorine and/or total chlorine in the water. The stabilized DPD solution may include N,N-diethyl-p-phenylenediamine oxalate salt, a polymeric anhydride such as a methyl-vinyl anhydride and an organo-sulfate such as dimethylsulfone.Type: GrantFiled: June 20, 2014Date of Patent: January 17, 2017Assignee: Hach CompanyInventors: Ibrahim A. Ismail, Matthew Hertel, Teresa Lynn Swanson

Patent number: 8852514Abstract: An electronic device for analyzing an aqueous solution may comprise a housing, one or more measurement circuits and a control circuit all arranged inside the housing. The housing may be configured to receive a test element. The one or more measurement circuits may be configured to produce one or more corresponding sets of measurement signals relating to an aqueous solution received on the test element. The control circuit may include a memory having instructions stored therein that are executable by the control circuit to process the one or more sets of measurement signals to determine one or more corresponding characteristics of the aqueous solution.Type: GrantFiled: September 11, 2013Date of Patent: October 7, 2014Assignee: Hach CompanyInventors: David Alexander Nathaniel Morris, Teresa Lynn Swanson

Patent number: 8142722Abstract: An apparatus for analyzing an aqueous solution, as may be implemented with a hand-held portable electronic device (10) and test element (16). A test pad (32) of the test element responsive in color to a characteristic of an aqueous solution is interrogated by the device by measuring intensity values of an interrogating test light as reflected off of the test pad. The test pad may be supported on an opaque and non-reflective substrate (28) that cooperates with an opaque edge portion (14E) of a test element placement member (14B) and associated side walls (14W) of the device to minimize the impingement of ambient light onto the test pad during interrogation.Type: GrantFiled: August 8, 2007Date of Patent: March 27, 2012Assignee: Hach CompanyInventors: David Alexander Nathaniel Morris, Teresa Lynn Swanson
