Apparatus for detecting proper strip insertion into an optical reflectance meter

摘要: A method and apparatus for detecting proper strip insertion into an optical reflectance meter. An electrical or electromagnetic device within the meter launches a signal when test is inserted therein. The which designed use in such contains material enhances coupling of to receiver then receives will not produce reading until level received. Use special present invention comprises more cost effective system detection dependent upon clean optics as prior art devices. therefore ensures reliable protection with ability distinguish only whether has been incorrectly by user, but also was it inserted.
