Described photogate 6 is installed on metal link rod 5, is provided with droplet counter (not shown) in it.The acid (alkali) that drip nozzle 41 drips is through this photogate 6, and the break-make number of times of droplet counter counting photogate 6, what namely can count the acid (alkali) of dripping from drip nozzle 41 drips number, thus can draw acid (alkali) amount participating in reaction accurately.Described photogate 6 is provided with a location-plate 61, and location-plate 61 is provided with some pilot holes 62.Described drip nozzle 41 inserts described pilot hole 62, thus ensures that the acid (alkali) that drip nozzle 41 drips can by droplet counter 61 record.
Described beaker 8 is placed on magnetic stirring apparatus 7, and it is positioned at the below of buret 4, can fill the alkali (acid) of concentration to be measured in it.Described magnetic stirring apparatus 7 comprises a stirring rotator 71, and this stirring rotator 71 is placed in beaker 8, drives stirring rotator 71 to rotate by magnetic stirring apparatus 7, thus makes N-process abundant, fast.
Described pH sensor puts 9 in beaker 8, and it can detect the pH value in beaker 8.
Described data acquisition unit 10 is connected with droplet counter 61, pH sensor 9 respectively, its can read participate in reaction the amount of acid (alkali) and beaker 8 in pH value, and send data to computer 12, computer 12 can be drawn acid base neutralization titration curve exactly and determine titration end-point.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
