Description
Technical field
The present invention relates to electronic technology field, particularly relate to a kind of new liquid dissolved oxygen electronic detector.
Background technology
Dissolved oxygen meter measures the principle of work of dissolved oxygen in liquid: the oxygen in liquid must be transmitted through the surface that film reaches negative electrode and could be reduced by dissolved oxygen meter electrode.Therefore, oxygen need overcome some resistances, wherein most importantly near the liquid-film resistance of film and the resistance of film itself being diffused into cathode surface.Be that main resistance should drop on film to dissolved oxygen meter electrode very important point, namely drag of film is much larger than liquid-film resistance, and the change of the resistance that the flowing of such fluid to be measured causes can reduce to minimum to the impact that oxygen spreads.So must meet when adopting dissolved oxygen meter to measure dissolved oxygen DO in liquid: 1, liquid should have certain flow velocity; 2, liquid internal should with the exchange of extraneous anaerobic.But, existing dissolved oxygen detector needs a large amount of fluid samples to keep flow state, just can reach testing goal.This just causes a large amount of fluid sample losses, increases testing cost.And for only having the liquid of a small amount of sample, owing to can not meet above-mentioned two conditions, often there will be and cannot detect or problem that prohibited data detection is true.For addressing this problem, the invention provides and a kind of new liquid dissolved oxygen electronic detector.
