Efficient pH value detection device

Abstract

The invention discloses an efficient pH value detection device which comprises a conveying belt and solution vessels, wherein the solution vessels are arranged on the conveying belt at intervals; a rotary device is arranged on the outer side of the conveying belt; a lifting device is arranged on the rotary device; a first supporting rod and a second supporting rod which extend outwards are arranged on the top of the lifting device; a first pH value detection head is arranged at the tail end of the first supporting rod; a second pH value detection head is arranged at the tail end of the second supporting rod; a first cleaning tank and a second cleaning tank are arranged on the two sides of the rotary device symmetrically. In this way, according to the efficient pH value detection device provided by the invention, when the solution vessels are conveyed on the conveying belt, the rotary device and the lifting device are adjusted, so that the bottom of the second pH value detection head is cleaned in the first cleaning tank when solution in the solution vessel is detected by the bottom of the first pH value detection head, the waiting time is reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of detection instruments, in particular to a high-efficiency detection device for pH. Background technique [0002] There are three main methods of pH measurement: the first is to add a pH indicator to the solution to be tested, different indicators will change color according to different pH values, and the range of pH can be determined according to the research of the indicator; the second is It is to use pH test paper, dip a little of the solution to be tested on the test paper with a glass rod, and then obtain the pH of the solution according to the color change of the test paper and compare it with the color card; the third is to use a pH meter, which is a kind of measurement An instrument for the pH of a solution, which measures the pH of a solution through a pH selective electrode. [0003] The steps of measuring pH value with pH indicator and pH test paper are cumbersome and the accuracy is not high, while th...

Problems solved by technology

[0003] The steps of measuring pH value with pH indicator and pH test paper are cumbersome and the accuracy is not high, while the pH meter can be accurate to two decimal places. Therefore, more and more pH meters are used, but the pH meter must be cleaned after each use. , unable to detect continuously, the waiting time is long, which reduces the efficiency of work
