Product Overview

CHUERA-C158D is a smart surface resistance testing instrument developed for ESD inspection and workplace monitoring. It combines resistance measurement with temperature and humidity detection, allowing several environmental and electrical parameters to be checked from one device.

The handheld design is paired with two external test electrodes, providing a practical setup for routine measurements on work surfaces and grounding points.

Integrated Measurement Functions

The tester supports a resistance measurement range of 0 to 1000GΩ. In addition to resistance testing, it can monitor temperature from -10°C to 80°C and humidity from 0 to 100% RH.

This combination allows users to record electrical test results together with the surrounding environmental conditions, which can be useful when maintaining ESD inspection records.

Touchscreen Operation

A 4.3-inch touchscreen provides the main interface for operation and data viewing. Test results can be displayed directly on the instrument, helping operators check measurements without relying on a separate computer during routine inspections.

The interface also supports parameter setup and test record management.

Barcode and QR Code Support

CHUERA-C158D includes barcode and QR code scanning functionality. Test objects can be associated with their corresponding identification codes before measurement, helping organize inspection data when multiple workstations, surfaces, or test points need to be tracked.

This function is particularly useful for structured inspection procedures where traceable records are required.

Local Test Record Storage

Test records can be retained on the instrument for later review. Measurement information can therefore be organized according to the actual inspection process instead of being written down manually after every test.

The stored data can also support subsequent record handling and reporting workflows.

Network Connectivity

The CHUERA-C158D supports wireless Wi-Fi and wired Ethernet communication. After the communication parameters are configured, the tester can connect with a computer or network system for data access and equipment management.

This design provides an option for integrating individual testing devices into a connected ESD inspection environment.

Temperature and Humidity Monitoring

Environmental conditions can affect ESD control and resistance measurements. CHUERA-C158D incorporates temperature and humidity measurement so these values can be viewed alongside resistance test results.

The temperature measurement range is -10°C to 80°C, while the humidity range is 0 to 100% RH.

Test Result Alerts

The instrument includes an alarm function for monitoring preset resistance limits. When the measured value exceeds the configured limit, the display indication changes to help draw the operator's attention to the result.

This provides a straightforward way to identify measurements that require further checking.

Rechargeable Design

The tester uses a DC12V charging supply and has a built-in rechargeable battery. According to the product specifications, the unit weighs approximately 1 kg, making it suitable for movement between different inspection locations.
