Portable Surface Resistance Measurement

CHUERA-030B Vertical Surface Resistance Tester is designed for checking the electrical resistance characteristics of surfaces in production and inspection environments. The unit combines resistance measurement with temperature and humidity monitoring, giving users additional environmental information during testing.

Its handheld meter and dedicated testing accessories are supplied in a protective carrying case, making the instrument convenient for laboratory work, factory inspection, quality control, and on-site measurements.

Wide Measurement Coverage

The CHUERA-030B supports a resistance measurement range of 10³–10¹² Ω. This broad range allows the instrument to be used for different surface resistance inspection requirements rather than being limited to a narrow resistance interval.

The digital display provides a direct reading during measurement, helping operators check the measured value without complicated interpretation.

Integrated Environmental Readings

In addition to resistance measurement, the tester can display temperature and humidity information. Environmental conditions can affect electrostatic and surface resistance measurements, so having these values available during inspection provides useful reference information for testing records.

The specified operating humidity range is 0%–100% RH, while the operating temperature range is 0°C–100°C.

Simple Handheld Operation

The instrument is designed with a straightforward handheld format for routine measurements. Its compact dimensions of approximately 180 × 95 × 40 mm allow it to be carried between different inspection locations.

The supplied test accessories provide the necessary contact components for surface resistance measurement, while the carrying case helps keep the meter and accessories together during transportation and storage.

Low-Battery Indication

The tester operates with a DC 9V power supply and includes a low-battery indicator. When the battery voltage drops below the specified level, the indicator provides a reminder so users can replace or recharge the power source as needed.
