Description
技术领域technical field
本发明涉及一种检测装置，具体是一种适用于滴定管、吸量管等管形量器的高精度无渗漏式管形量器标定校准装置及使用方法。The invention relates to a detection device, in particular to a high-precision non-leakage tubular measuring device calibration and calibration device suitable for tubular measuring devices such as burettes and pipettes, and a method of using the same.
背景技术Background technique
现有的管形量器的校准操作方式(如图5所示)为：The calibration operation mode of the existing tubular gauge (as shown in Figure 5) is:
1、手持管形量器A，将其流液口完全没入检测液体中；1. Hold the tube-shaped measuring device A, and completely immerse its liquid outlet into the testing liquid;
2、捏紧吸气皮球，排空其中的气体，将皮球吸气嘴与管形量器的顶端紧密贴合；2. Pinch the suction ball tightly, empty the gas in it, and tightly fit the suction nozzle of the ball to the top of the tube-shaped measuring device;
3、放松吸气皮球，液体被吸入管形量器中，进行手工调液；3. Relax the suction ball, the liquid is sucked into the tube-shaped measuring device, and the liquid is adjusted manually;
4、将吸气皮球与管形量器分开，管形量器中的所标定液体缓慢注入空容器中，可用称量法，根据液体相应密度，测得空容器中所标定液体的容量。4. Separate the suction ball from the tubular measuring device, and slowly inject the calibrated liquid in the tubular measuring device into the empty container. Weighing method can be used to measure the volume of the calibrated liquid in the empty container according to the corresponding density of the liquid.
该管形量器存在的缺陷在于：使用吸气皮球时利用大气压力进行吸液，需要依靠人工操作才能将液体吸量至指定液位，对操作人员熟练度要求高；因此校准操作重复性、稳定性差。The defect of this tube-shaped measuring device is: when using the suction ball, the atmospheric pressure is used to absorb the liquid, and manual operation is required to absorb the liquid to the specified liquid level, which requires high proficiency of the operator; therefore, the calibration operation repeatability, Poor stability.
由于使用管形量器的企业行业涉及面广，如食品、医药生产企业、农业及化工等行业，校准工作需求量较大(每年达上万次)，管形量器的示值误差直接影响着企业的生产经营活动。目前管形量器使用范围较广，对操作人员要求较高，发明一种操作相对简便、精确度更高、安全性和工作效率更高的校准装置具有迫切需求。Due to the wide range of industries that use tubular gauges, such as food, pharmaceutical production enterprises, agriculture and chemical industries, the demand for calibration work is large (up to tens of thousands of times per year), and the indication error of the tubular gauge directly affects the production and operation activities of the enterprise. At present, the tube-shaped measuring device has a wide range of use, and has high requirements for operators. There is an urgent need to invent a calibration device with relatively simple operation, higher accuracy, higher safety and work efficiency.
