Electrostatic Field Meters

Electrostatic field meters help quality and ESD teams understand whether insulators, process materials, or isolated conductors are carrying a charge that could threaten sensitive devices.

Where field meters add value

They are especially useful during incoming material evaluation, packaging reviews, workstation troubleshooting, ionizer verification, and process change investigations.

What teams should look for

• Stable repeatability at the intended measuring distance
• Clear operating procedure for grounded reference measurements
• Documented calibration and traceability

Field data becomes useful only when the measuring distance, grounding condition, and process state are controlled.

Good practice

Use a defined test distance, record ambient conditions when relevant, and correlate high field readings with real process outcomes instead of treating every reading as a failure on its own.
