Static Testing Equipment
Name：LFY-403B Digital Charge Tester
Details
The main purposeUnder laboratory conditions, evaluate the electrostatic characteristics of the mask product, that is, test the charge of the mask. It can also measure the charged charge of various powders, liquids and solids.
Instrument characteristics
1. This instrument is a 4 1/2-digit digital display charge meter designed for measuring the charge of an object. It is composed of a small Faraday tube and an electrostatic potentiometer, and directly reads the charge value of the sample. Due to the use of large-scale integrated circuits, high input impedance operational amplifiers and high-precision precision capacitors, the instrument has the advantages of high accuracy, stable performance, small size, simple operation and convenient use. It can be matched with Faraday tubes of any shape and size.
2. There is no need to calculate, and the charge value can be directly displayed in figures.
3. High precision, high resolution and good linearity.
4. The reading is stable.
5. Equipped with a reset switch, which is easy to operate.
Technical index
1. Measuring range of electrostatic charge: measuring range: ±10pC ～±2μC;
2. 4 1/2-digit digital display, which can display the positive and negative polarity of the charge, and the negative polarity shows the "-" sign;
3. Accuracy: ±0.5%;
4. Faraday tube size: inner tube: 15cm*20cm
Outer cylinder: 17cm*23cm
