Description

Portable pH value detector
Technical field
The present invention relates to a kind of instrument, especially a kind of portable pH value detector.
Background technology
PH value is the negative logarithm of hydrogen ion activity in the solution, is one of the most frequently used water-quality guideline.The pH value of natural water is many in 6~9 scopes; PH value of drinking water requires between 6.5~8.5; The pH value of some process water must remain between 7.0~8.5, is corroded to prevent hardware and pipeline.Noxious material was also handled, estimates to the pH value at wastewater biochemical aspects such as toxicity have directive significance.
The pH value detector is the important tool of measurement and reaction solution potential of hydrogen, measures the solution pH value with potentiometry.PH value detector meter is widely used in fields such as industry, electric power, agricultural, medicine, food, scientific research and environmental protection.This instrument also is the indispensable inspection machine in food factory, potable water administrative office in a factory QS, the HACCP authentication.The precision of pH value detector is particularly important, but existing P H detector comprises glass electrode, metal-metal oxide solid electrode, ion-selective electrode, light transmitting fiber pH sensor, chemical modification pH sensor, ion sensitive field effect pipe pH meter, pH enzyme sensor, liquid pH value detector etc., these PH detector tests are insensitive, signal to noise ratio (S/N ratio) is not high, is subjected to the interference of other ion again easily.
In order to address the above problem, Chinese patent CN 202956358 U disclose a kind of PH detector, and this detector error is little, the precision height, and the life-span is long.It comprises constant potential source, current value-pH value conversion instrument and the probe that is connected in series successively, and described probe is formed by working electrode with to electrode.Be to measure the current value in the loop of flowing through under constant voltage according to principle, the size of current value is directly proportional with hydrogen ion activity, perhaps is directly proportional with the pH value.Behind the corresponding relation with the solution correcting current value of standard pH value and pH value, according to the size of survey electric current, namely can determine the pH value of solution.But the shortcoming of such PH detector device is: little or when detecting the liquid off-capacity at container bottom, probe can not touch and detect the pH value that liquid namely can not detect solution at the container bore that detects liquid when dress; When perhaps detection liquid is filled in container, put into probe and will cause overflowing of detection liquid, if it is easy to run into strong acid and strong base, security incident takes place easily.
Owing to there is such problem, be necessary existing pH value detector is improved.
Summary of the invention
The objective of the invention is a kind of liquid container bottleneck size that no matter detects of designing for the deficiency that solves above-mentioned technology, how many portable pH value detectors that can both conveniently detect of solution.
The portable pH value detector that the present invention is designed, comprise housing, the housing side is provided with handle, be provided with the constant potential source, current value-pH value conversion instrument and the probe that are connected in series successively in the described housing, described probe is formed by working electrode with to electrode, be provided with a dividing plate in the described housing, this dividing plate and housing bottom surface form chamber, described chamber links to each other with a getter device, and be provided with suction casing in cavity bottom, described suction casing below is connected with flexible pipe, and described flexible pipe bottom is connected with flooded suction; Described constant potential source and current value-pH value conversion device epi-position is in the dividing plate top, and described probe passes dividing plate and stretches into the described current value of described suction casing-pH value conversion instrument and also links to each other with a display device that is located on the housing.
As preferably:
