Embodiment
The utility model diagram function technical scheme embodiment (as Fig. 1) is:
After the instrument POST preheating, picture and text display data processor secondary table (1) is carried out predetermined registration operation, according to the accuracy range of checked object, set instrument precision Γ value and space D value to be measured (with the test quiescent interval of minute timing) earlier, test can be from Γ maximum (or minimum value).After measuring beginning, instrument per 6 second once sampling, obtain the difference and the Γ value of adjacent two sampled signals simultaneously and determine relatively whether measurement reaches stable, during less than Γ, measurement begins to enter steady state (SS), the T consuming time of record test, T represents the response time of measurand under this degree of accuracy, after this occur continuously a plurality ofly during, illustrate to reach this accuracy class less than Γ, otherwise explanation this accuracy class inadequately, continuing to reduce (or increase) Γ value experimentizes, until the minimum value of obtaining Γ, this value is by the accuracy of calibrating object, and memory storage according to the order of sequence.From diagram, its shape is square and is parabolical trapezoidal composition on one side.
Test sample flow process (as Fig. 1,2,3,4) is in the utility model detection cell (8):
Sample is introduced by sample introduction pipe 25, and one the tunnel enters the conductivity chamber 23 of conductivity electrode 22, and be positioned sample pipe 24 overflows of overflowing of redundance are fallen, and photoconductive tube 1, photoconductive tube 2 21, pH electrode 19, pN are sent in another road
aIn the public measuring chamber 15 of electrode 20, when measuring dissimilar ion, make corresponding reagent kind and amount of reagent, follow procedure Control Software setting time (reaction time) and setting order intermittently in advance, start the pneumatic supply (not shown) of different reagent meters 12 successively, reagent by matter, add in the measuring chamber 15 according to quantity, on time, is reacted, measures.After reaction, measurement are finished,, be extracted into sample changer 11 and emit by the sample that U trap 9 will react, measure.Whole process can be carried out automatically again and again, if adopt by hand, a GPRS sample addition gets final product, and adds to utilize siphon to clean, discharge, and adds then less and does not discharge, and retains to be equipped with inspection.
