上皿天びんについての注意事項

上皿天びんに関する注意事項 周知のとおり, 精密天秤は精密電子機器の一種です, 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...

紙の通気度の測定

基本 圧力差法を使用して、前処理されたサンプルを上下の測定面の間に配置します, 一定の圧力差がサンプルの両側に形成されます。圧力差の作用により, ガスは高圧側からサンプルを通って低圧側に流れます。, サンプルの透過率は面積に応じて計算されます。, 圧力差とサンプルを通過する流量. Definition of breathability Average air flow through paper...

粗さゲージは複数のセンサーと組み合わせることができます

粗さゲージは複数のセンサーと組み合わせることができます さまざまなワークを測定する場合, 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, 傾斜面, conical surface, 内穴, groove and other surface roughness, can be carried out hand-held measurement, in addition to the standard sensor, other sensors need...

膜厚計の測定精度に影響を与える要因は何ですか

膜厚計の測定精度に影響を与える要因の説明 あ) Magnetic properties of the base metal Thickness measurement by magnetic method is affected by the change of the magnetic properties of the base metal (in practical application, 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...

表面粗さ計の原理と応用を理解する

粗さ計は表面粗さ計とも呼ばれます, 表面仕上げ装置, 表面粗さ検出器, 粗さ測定器, 粗さ計, roughness tester and other names. It was first developed and produced abroad and then introduced into China. Roughness meter measuring the surface roughness of workpieces, put the sensors on the workpiece surface to be tested, by instrument internal drive mechanism drive the sensor do constant speed glide along the surface to be tested, sharp sensor through the built-in stylus feel the...

膜厚計の技術原理を理解する必要がある

磁気吸着測定の原理 磁石間の吸引量 (調査) 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...
