CARD TYPE MULTI-METER FOR SIMPLY MEASURING CONDUCTIVITY, DISSOLVED OXYGEN, PH CONCENTRATION, SWEETNESS, AND ACIDITY

摘要

PURPOSE: A card type multi-meter is provided to ensure simple portability, to measure a small amount of sample, and to simply measure conductivity, dissolved oxygen, and acidity.;CONSTITUTION: A card type multi-meter comprises: a measuring sensor which is formed in a part of card and is used for measuring sample ingredients by dropping a drop of sample; a print circuit board(11) which is formed in a card shape together with the measuring sensor; a display part(12) which displays measured value and is attached on a surface of the print circuit board by SMT(surface mount technology); a solar cell(13) which supplies power by being attached onto the surface of the print circuit board; and a meter body(10) having an on/off switch(14).;COPYRIGHT KIPO 2012
