LFY-403B Digital Charge Tester
The main purpose
Under laboratory conditions, evaluate the electrostatic characteristics of the product by testing its charge level. It can measure the charged amount of various powders, liquids, and solids.
Instrument characteristics
1. This instrument is a digital display charge meter designed to measure the charge of an object. It consists of a small Faraday tube and an electrostatic potentiometer, which can directly read the charge value of the sample. Due to the use of components such as large-scale integrated circuits, high input impedance operational amplifiers, and high-precision precision capacitors, this instrument has the advantages of high accuracy, stable performance, small size, simple operation, and convenient use. It can be combined with any shape and size of Faraday tube and other advantages.
2. No calculation required, display the charge value directly in numbers.
3. High precision, high resolution, and good linearity.
4. The reading is stable.
5. Equipped with a reset switch, the reset operation is convenient.
