精密天平注意事项

精密天平注意事项众所周知, 精密天平是一种精密电子仪器, which is widely used in laboratory and medical fields.This electronic balance uses a higher precision sensor and more control chip, so it has higher precision and sensitivity than ordinary electronic balance.Although the precision balance has many advantages, it is easy to be interfered by external factors, electromagnetic and other factors, which will produce certain errors. So how can we improve the accuracy...

纸张透气度的测定

基本原理采用压差法将预处理后的样品置于上下测量面之间, and a constant pressure difference is formed on both sides of the sample.Under the action of pressure difference, the gas flows from the high pressure side through the sample to the low pressure side, and the permeability of the sample is calculated according to the area, pressure difference and flow through the sample. Definition of breathability Average air flow through paper...

粗糙度仪可与多个传感器配对

粗糙度仪可与多个传感器配对 当我们测量不同的工件时, we will match different sensors for measurement.So how many sensors can roughness gauge be matched with?How many sensors are there?The following Xiaobian to answer Sensors are divided into: 1. Standard sensors Standard sensors use the most sensors, it can measure most of the plane, inclined plane, conical surface, 内孔, groove and other surface roughness, can be carried out hand-held measurement, in addition to the standard sensor, other sensors need...

影响涂层测厚仪测量精度的因素有哪些

影响涂层测厚仪测量精度的因素说明 A) Magnetic properties of the base metal Thickness measurement by magnetic method is affected by the change of the magnetic properties of the base metal (在实际应用中, the change of the magnetic properties of the low carbon steel can be considered to be slight). In order to avoid the influence of heat treatment and cold working factors, the standard sheet with the same properties as the sample base metal should...

了解表面粗糙度仪的原理及应用

有必要了解涂层测厚仪的技术原理

磁吸力测量原理 磁铁之间的吸力大小 (探测) and the magnetic steel is proportional to the distance between the two, which is the thickness of the coating.Using this principle to make a thickness gauge, as long as the difference between the magnetic conductivity of the coating and the substrate is large enough, it can be measured.Since most industrial products are made of structural steel and hot and cold rolled steel sheets, magnetic thickness gauges are...
