It blocks.
A kind of preceding raising soil alkali-hydrolyzable nitrogen diffusion boat testing result accuracy device, baffle is towards the side of through-hole
On be provided with sealing ring.
A kind of preceding raising soil alkali-hydrolyzable nitrogen diffusion boat testing result accuracy device, the upper end of mobile bar is provided with
Handle.
The upper surface of a kind of preceding raising soil alkali-hydrolyzable nitrogen diffusion boat testing result accuracy device, bottom plate is indent
Face.
A kind of preceding raising soil alkali-hydrolyzable nitrogen diffusion boat testing result accuracy device, a diameter of 3mm on labyrinth.
The utility model has the beneficial effects that：
（1）Convex edge is arranged in the utility model in ware lid, makes ware lid be combined rear ware lid not occur with ware body by convex edge
It deviates and causes poorly sealed phenomenon；The interval setting convex block on the lateral wall of ware lid convex edge again, on the madial wall of mistress
Interval setting and the matched groove of convex block, ware lid and ware can just be made by rotating by a certain angle after ware lid is covered on ware body
Body closely connects, and makes ware lid and the offset that ware body combination ware lid had both been not in left and right directions in this way, upper and lower will not occurs
To loosening, be effectively improved the leakproofness of diffusion boat；
（2）The utility model is provided with the labyrinth being connected to mistress in the lateral wall of mistress, when needs indoor addition outward
When reagent, ware lid need not be opened, reagent can need to be only added to outer interior by labyrinth, avoids trying when opening ware lid
The volatilization of agent ensure that the accuracy of measurement result；
（3）The utility model offers through-hole in the lower end of interior room, and baffle is arranged outside through-hole, and baffle moves up and down can
The open and close for realizing through-hole only need to be by mobile bar by baffle when needing outer indoor reagent being added in interior room
It is promoted, outer indoor reagent can enter interior room from through-hole, carry out the reaction between reagent；
（4）The utility model is provided with sealing ring on side of the baffle towards through-hole, to improve baffle and through-hole
Between leakproofness；
（5）The utility model sets the upper surface of bottom plate to inner concave, when not only can avoid shaking diffusion boat
Liquid sloshing in mistress enters interior room from the upper port of interior room, can also it is necessary to when facilitate liquid in mistress from logical
Hole enters interior room.
