EST111 Electrostatic Charge Meter is a device used to measure the charged electrical charge of anti-static work clothes and textiles, the charged electrical charge density, various powders, liquids, solids, static spark discharge energy, friction charging series, measuring the capacitance of static conductors, measuring the surface potential and surface charge density of objects. The instrument has the advantages of high accuracy, wide measurement range, stable performance, small size, simple operation and convenient use.
The EST111 is a digital static‑charge meter designed to measure charge quantity and surface charge density of fabrics, powders, liquids, solids, and static discharge events. It features a three‑digit LED display, high accuracy, wide measurement range, and a zero‑adjustable function.
The manual covers preparation steps, panel controls, range selection, fuse replacement, zeroing procedure, typical applications, and warranty information, helping users operate the instrument safely and accurately. This manual is written in Chinese.
