Product Description

The SGB-C series AC/DC digital high-voltage meters are general-purpose high-voltage measuring instruments, suitable for measuring industrial 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 use and portability.

Product Features

High precision

Utilizing precision high-voltage thin-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 product for high-voltage static voltage meters.

2. Excellent anti-interference performance

Utilizing special shielding technology, the aluminum alloy pressure equalization ball features a smooth and glossy surface, effectively improving the electric field distribution around the ball to prevent sharp discharge and enhance the anti-interference capability of the measurement data. The low-voltage display gauge is enclosed with a full-metal structure for shielding, while the high-voltage divider and low-voltage display gauge are connected using high-quality coaxial cables to minimize the impact of high voltage on the readings, thereby achieving high stability and linearity.

3. Safe and reliable

This instrument is composed of a high-voltage voltage divider and a low-voltage display gauge. The high-voltage voltage divider utilizes DuPont filling material and is sealed with special technology, resulting in a smaller structure, lighter weight, and reduced internal partial discharge to an absolute minimum, offering higher reliability. No oil leakage issues exist. During operation, the high-voltage voltage divider and low-voltage gauge are connected using a coaxial cable, with a significant distance between the high and low voltage sections, ensuring safe and reliable operation.

4. Easy 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. Easy to carry

The portable structure is encased in an aluminum alloy packaging box, allowing for easy assembly and disassembly. It's compact, lightweight, and convenient to carry, making operation a breeze.
