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... 15Oct
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
Roughness gauges can be paired with several sensors
Roughness gauges can be paired with several sensors When we measure different 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, inner hole, groove and other surface roughness, can be carried out hand-held measurement, in addition to the standard sensor, other sensors need... 05Jun
