Non-Contact Measurement for Static Voltage Checks

The CHUERA-520D is designed for situations where direct contact with the tested surface is not preferred. Its non-contact measurement method allows operators to check electrostatic voltage on surfaces while keeping the sensing head away from the test object.

With a measurement range from -2000V to +2000V, the instrument can be used for a broad range of routine static electricity inspections.

A Practical Tool for ESD Monitoring

Static electricity can vary during production, handling, and material movement. The CHUERA-520D helps operators observe these changes directly through its color display.

The instrument is suitable for checking static conditions on work surfaces, materials, equipment, and other accessible objects in ESD-controlled areas. It can also support periodic inspection work when verifying the effectiveness of static protection measures.

Color Display and Adjustable Settings

The color display provides a straightforward view of the measured voltage and operating information. The 0.1V resolution allows small changes in the displayed reading to be observed during measurement.

The operating interface uses buttons rather than a complicated menu structure, making routine measurements convenient for production and maintenance personnel.

Built-In Data Recording

The CHUERA-520D can store up to 10 × 10 measurement records. With a sampling rate of 1 to 10 measurements per second, the instrument can capture changing static voltage conditions during an inspection.

Recorded data can be useful when comparing different testing points or reviewing measurements after a site inspection.

Alarm Function for Out-of-Range Conditions

An adjustable alarm function is included for situations where the measured static voltage exceeds a preset value. This gives operators an immediate visual indication during testing and can help identify areas that require additional ESD attention.

Rechargeable and Portable Design

The meter uses a built-in lithium battery and supports charging through a Type-C interface. The compact housing measures approximately 165 × 80 × 28 mm, making it easy to carry between workstations.

The non-contact probe has a sensor length of approximately 50 mm, providing practical clearance between the measuring head and the surface being checked.

Typical Applications

Why Choose the CHUERA-520D

The CHUERA-520D brings measurement, display, recording, and alarm functions into one handheld device. Its non-contact design reduces the need to physically touch the tested surface, while the rechargeable battery and compact housing make it suitable for repeated inspection work across different areas.

For manufacturers and ESD management teams, it provides a convenient way to check surface static voltage and keep measurement information available for routine quality and maintenance work.
