Description
Technical field
The utility model relates to detecting instrument field, particularly relates to a kind of portable PH meter.
Background technology
Hydrogen ionexponent refers to the ratio of hydrionic sum and total amount of substance in solution.Its numerical value is commonly called as " pH ".Represent the numerical value of solution acidic or degree of alkalinity, i.e. the negative value of the common logarithm of contained pH.There is a lot of method to measure the pH value of solution: use pH indicator.In solution to be measured, add pH indicator, different indicator, according to different pH value meeting changes colour, just can determine the scope of pH according to the research of indicator.During titration, accurate pH standard can be made; Use pH test paper.PH test paper has extensive test paper and precision test paper, dips in some solution to be measured, on test paper, then can obtain the pH of solution according to the color change reference standard colorimetric card of test paper with glass bar.PH test paper can not demonstrate the pH value of oil content, because pH test paper measures the pH value of solution to be measured with hydrogen ion, but not containing hydrogen ion in oil, therefore pH test paper can not demonstrate the pH value of oil content; Use pH meter.PH meter is a kind of instrument measuring solution ph, and it determines the pH of solution by pH choice electrode (as glass electrode).PH meter can be as accurate as 2 significant digits.Common PH meter is bulky, carries inconvenience.
Utility model content
The utility model is in order to overcome deficiency of the prior art, and provide a kind of portable PH meter, the utility model structure is simple, compact volume and convenience, and portable PH meter, the utility model measures numerical value accurately and reliably, and degree of accuracy is higher.
The utility model is achieved through the following technical solutions:
A kind of portable PH meter, be characterized in comprising housing, described housing is connected with sniffer, described sniffer comprises detection cavity, PH inductor is provided with in detection cavity, be provided with the accumulator, switch, display device, the pump that are connected with circuit board in described housing, described pump connects detection cavity by flexible pipe, and described circuit board control pump draws test solution to be measured in detection cavity by suction pipe.
Described switch comprises starting switch and reset switch.Handle is provided with above described housing.Described display device comprises display screen and hummer, and display screen display pH value, pH value reported by hummer.
Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of portable PH meter, and the utility model structure is simple, compact volume and convenience, and portable PH meter, the utility model measures numerical value accurately and reliably, and degree of accuracy is higher.
