With the continuous advancement of science and technology, various detection technologies are also developing rapidly. As a detection tool, the first and most important characteristics are high technological content, complex structure and many more varieties, large quantities.
For example, various ultrasonic oscillators, vacuum drying ovens, electronic balances, etc. These devices have low unit prices, many varieties and large quantities, and are suitable for basic testing tasks, electronic tensile testing machines are relatively professional testing equipment, with high precision and variety, many and at the same time high technical content. Users must attend the instrument manufacturer's training and on-the-job training of test farms.
When an error occurs, it is difficultcan only be corrected by the maintenance personnel of the device and must contact the manufacturer for processing.
