Smartfilm resistance tester package

Smartfilm resistance tester package

When making electrode strips(busbar) for smartfilm, a correct and perfect resistance value is very important to the usage life of the smartfilm project  In most cases, workers who make busbar often rely on their own experience and feel to wipe off the liquid crystal molecules, but the liquid crystal molecules are wiped too much. Too much or too little wiping will cause the smart film to fail to obtain the correct resistance value, which requires a professional resistance meter to test.

The ST-21 smartfilm resistance tester is a new generation product among the four-probe smartfilm resistance testers. It is designed in accordance with similar national standards and the Mainland A.S.T. Mountain standard. It is specially designed to measure semiconductor film resistance (or thin house resistance, surface resistance). Resistance, unit / mouth) new instrument. Can be used to measure general semiconductor materials, conductive films (such as ITO

Sheet resistance of transparent conductive oxide film)•⋯ and other similar substances.

This instrument uses large-scale integrated circuits as its main core: it uses a reference power supply and an operational amplifier to form a high-precision steady current

source; with loop effective normal indication circuit: and equipped with a large LCD display reading, making the instrument small in size and light in weight.

It has the characteristics of light weight, beautiful appearance, easy operation, fast measurement speed and high precision.

Features: Using large-scale integrated circuits as the main part of the instrument, the measurement is accurate and stable, and has low power consumption.

Large-screen LCD displays readings, intuitive and clear

Volume<175mmX90mmX42mm Weight<300g

Measuring range: Divided into two levels according to the size of the square resistance measurement value

1. Block resistance: 1~199 ohms

2.10~1999 ohms

Error<0.8%

Power supply: one 9V laminated battery

The square four-probe probe is a square-shaped four-probe probe that is specially used to measure the resistance of semiconductor thin films. It is used with a square resistance tester. It is a four-probe probe that is specially used to measure small samples. It can be used for general semiconductor materials, conductive films, ITO transparent Oxide film, sheet resistance of similar substances.
