EST111 Electrostatic Charge Meter is a device for measuring the charge of an object. It is mainly used to measure the charged charge quantity and charged charge density of anti-static work clothes and fabrics, which conform to the requirements of national standards GB12014 and 12704. The measurement range is wide, suitable for the needs of different test objects, high accuracy, high resolution, good linearity, stable reading, and a reset switch for easy operation.
The EST111 Electrostatic Charge Meter is designed to measure charge quantity, charge density, and static spark discharge of various objects. It features a 12‑digit display, high accuracy, wide measurement range, and simple operation.
The manual explains how to set up the instrument, select measurement ranges, use a Faraday cup when needed, perform zeroing, and maintain the device. Warranty information and typical applications such as anti‑static workwear testing are also provided. This manual is written in Chinese.

Press the ZERO CHECK switch and, if the display is not zero, adjust the ZERO knob until the reading shows zero.
The instrument provides four ranges: 20 nC, 200 nC, 2 µC, and 20 µC, selectable via the range switch.
No, metal conductors can be measured directly without using a Faraday cup.
The instrument comes with a free 36‑month warranty from the date of purchase.
