Notes on precision balance
Notes on precision balance As we all know, the precision balance is a kind of precision electronic instrument, 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... 15Okt
Determination of paper air permeability
Fundamentals The pressure difference method is used to place the pre-processed sample between the upper and lower measuring surfaces, 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... 05Jun
Ang mga gauge ng roughness ay maaaring ipares sa ilang mga sensor
Ang mga gauge ng roughness ay maaaring ipares sa ilang mga sensor Kapag sinusukat namin ang iba't ibang mga workpieces, 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, panloob na butas, groove and other surface roughness, can be carried out hand-held measurement, in addition to the standard sensor, other sensors need... 05Jun
What are the factors that affect the measurement accuracy of coating thickness gauge
Description of factors affecting measuring accuracy of coating thickness gauge 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 (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... 05Jun
Understand the principle and application of surface roughness instrument
Roughness instrument is also called surface roughness instrument, surface finish instrument, surface roughness detector, roughness measuring instrument, roughness meter, 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... 05Jun
