Product Description
Product Overview

The high-resistance megohmmeter is a precision electrical measurement instrument designed to measure insulation resistance and high-resistance values in electrical equipment and insulation materials. It is widely used in electrical testing laboratories, manufacturing quality control departments, research facilities, and industrial inspection environments.

By applying a specified DC test voltage and measuring the corresponding resistance, the instrument helps evaluate the electrical insulation characteristics of test samples and electrical components. Depending on the selected model, measurement ranges may extend from megohms to gigohms or teraohms, making the instrument suitable for a wide range of high-resistance measurement requirements.

Advanced models may also support multiple test voltages, automatic measurement, timed testing, and digital data management.

Frequently Asked Questions
Q1: What is a megohmmeter?

A megohmmeter is an electrical measuring instrument used to measure high electrical resistance, especially insulation resistance.

Q2: What is the difference between MΩ, GΩ, and TΩ?

MΩ represents megohms, GΩ represents gigohms, and TΩ represents teraohms. They represent progressively higher resistance measurement units.

Q3: What determines the accuracy of high-resistance measurement?

Accuracy can be influenced by the instrument's specifications, test voltage, temperature, humidity, test lead condition, and the characteristics of the test sample.

Q4: Is a high-resistance megohmmeter suitable for insulation material testing?

Yes. Suitable models can be used for high-resistance measurement of insulation materials and electrical components.
