Test element and tester for analyzing solutions |
摘要 |
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. |
