Product Description

The SGB-C series AC/DC digital high-voltage meter is a general-purpose high-voltage measuring instrument, suitable for measuring power frequency AC high voltage and DC high voltage in power systems, electrical appliances, and electronic equipment manufacturing departments.

The SGB-C series AC/DC digital high-voltage meters consist of a high-voltage measuring section and a low-voltage display instrument. During operation, the high-voltage section and the low-voltage instrument are separated, ensuring safe and reliable operation.

The SGB-C series AC/DC digital high-voltage meters feature a portable design, with the entire unit encased in an aluminum alloy packaging box for easy handling and transportation.

Product Features

High precision

Utilizing precision high-voltage film capacitors and high-voltage glass enamel resistors, the input impedance is high, reducing test current, minimizing power consumption, and enhancing the instrument's measurement accuracy and stability. The signal processing section employs high-performance OP for signal amplification, utilizes the new dual-integral AD sampling technology, and features a 4.5-digit LCD display, achieving the highest resolution of 0.001kV. It is an upgraded and replaced product for high-voltage static voltage meters.

2. Excellent anti-interference performance

Utilizing special shielding technology, the surface of the aluminum alloy pressure equalizing ball is smooth and lustrous, effectively improving the electric field distribution around the ball, preventing sharp edge discharge, and enhancing the anti-interference capability of the measurement data. The low-voltage display gauge features a full-metal enclosed structure for shielding, while the high-voltage divider and low-voltage display gauge are connected using high-quality coaxial cables, reducing the impact of high voltage on the readings, thus achieving high stability and linearity.

3. Secure and Reliable

This instrument is composed of a high-voltage voltage divider and a low-voltage display gauge. The high-voltage voltage divider uses DuPont filling material and is sealed with special technology, resulting in a smaller structure, lighter weight, and reduced internal partial discharge to the lowest level, ensuring higher reliability. There is no oil leakage issue. During operation, the high-voltage voltage divider and low-voltage gauge are connected with a coaxial cable, with a significant distance between the high and low voltage sections, ensuring safe and reliable operation.

4. Simple to operate

Switch between high and low voltage, AC and DC using a rotary switch for convenience and speed. A 4.5-digit LCD directly displays the measurement results, simple and intuitive. Brings convenience to on-site testing work.

5. Convenient to carry

Utilizing a portable structure, the entire unit is encased in an aluminum alloy packaging box, allowing for easy disassembly. Compact in size and lightweight, it is convenient to carry and use.
