To the commonly used volumetric glass in laboratory such as single line volumetric flask, graduated cylinder, measuring cup etc., regularly examine and determine, to guarantee the precision of all kinds of little measuring devices.Present calibrating to this class experimental facilities, the measurement verification of especially little measuring device also is confined in the manual operations, to all kinds of measuring devices through repeatedly experiment, with judge that the measuring device scale distributes whether evenly, accurately, judge that simultaneously its total volume is whether in error range.This manual calibrating mode length consuming time, quantity of sample handling are less, according to statistics, calibrating amounts generally props up at 20-30/day about, the people is that the error that causes is also big simultaneously, has influenced the efficient and the precision of device calibrating in a small amount.
Summary of the invention
Problems such as the utility model is low at the efficient that the manual calibration method of existing a small amount of device exists, low precision provide a kind of efficient height, a small amount of device automatic gauge calibrating installation that precision is high examined and determine.
A small amount of device automatic gauge calibrating installation of the present utility model is by the following technical solutions:
This a small amount of device automatic gauge calibrating installation comprises constant temperature oven, displacement transducer, automatic liquid adding device, the numeral measurement mechanism of taking pictures, liquid storage container, electronic scale and computing machine, electronic scale, the numeral measurement mechanism of taking pictures, automatic liquid adding device, displacement transducer and liquid storage container all are arranged in the constant temperature oven, automatic liquid adding device and displacement transducer are positioned at the top of electronic scale, displacement transducer is arranged on the fixed cross beam of automatic liquid adding device, the suction inlet of automatic liquid adding device stretches in the liquid storage container, electronic scale, the numeral measurement mechanism of taking pictures, automatic liquid adding device all is connected with computing machine with displacement transducer.
During calibrating, the temperature constant in the constant temperature oven at 20 ℃, is left standstill after 10 minutes and brings into use, guarantee that environment temperature and the interior water temperature of liquid storage container that detecting instrument is required all remain on 20 ℃.The little measuring device that needs are identified is placed on the electronic scale.The numeral measurement mechanism of taking pictures is taken pictures to little measuring device, analyze the homogeneity of device scale in a small amount, measure the height of little measuring device simultaneously in different scales position, with this elevation information input computing machine, automatically calculate the liquid feeding volume of these positions by computing machine, and control automatic liquid adding device a small amount of device liquid feeding.Displacement transducer is measured the height of liquid level, when the liquid feeding height meets the demands (reach numeral take pictures the height at the different scales place that measurement mechanism provides), stops liquid feeding.Whether the computer run statistics program actual volume and the corresponding standard volume of little measuring device when each scale position compared, and then it is qualified to judge little measuring device.
The utility model is examined and determine little measuring device under temperature constant state, can realize the batch calibrating of little measuring device, and the calibrating amount has improved calibrating efficient greatly more than 200/day, also can effectively avoid personal error simultaneously, improves the calibration accuracy of little measuring device.
