Features
Accurately measures human-body electrostatic potential under standard walking conditions.
Reflects true antistatic characteristics of carpets and floor coverings.
High input resistance and low electrode capacitance ensure precision results.
Compact and durable design suitable for laboratory or on-site testing.
Enables integration with data logging and reporting systems for quality control.
Test Principle
When a person walks on the inspected carpet wearing the shoes specified in the standard and following the prescribed walking pattern, and is under monitored atmospheric conditions, the potential difference relative to the earth's voltage (0 potential) generated during walking is measured. This measurement is used to evaluate the risk level of discomfort caused by static electricity shocks during the use of this carpet. We use the electrostatic potential difference between the human body and the earth to represent human - body static electricity. The testers walk on the inspected carpet (floor covering) wearing the test shoes specified in the standard and following the prescribed walking pattern in a regulated atmospheric environment. At this time, measuring the human - body electrostatic potential actually reflects the electrostatic characteristics of the potential of equal - magnitude and opposite - polarity charges carried by the carpet.
