Product Description

ESD Testing Probes Description

ESD (Electrostatic Discharge) testing probes are specialized tools used to evaluate and measure electrostatic discharge on surfaces, equipment, and personnel. These probes are an essential part of ESD audits, compliance checks, and workplace safety standards.

General Description:

ESD testing probes are handheld or connected devices used to simulate or detect static charge and discharge behavior in an ESD-protected area (EPA). They work alongside ESD testers or meters to measure surface resistance, wrist strap continuity, footwear grounding, and static charge levels.

Types of ESD Testing Probes:

1. Surface Resistance Probes

   • Used with surface resistance meters (per ANSI/ESD STM11.11 / STM11.12)

   • Measures surface resistance in ohms or ohms/square

   • Usually come in a pair (2.27 kg, 5 lbs each)

2. Wrist Strap/Footwear Test Probes

   • Part of wrist strap or footwear testers

   • Ensure operators are properly grounded before entering ESD-safe zones

3. Point-to-Point Probes

   • Used to measure resistance between two specific points

   • Good for checking continuity on ESD mats, floors, or garments

4. Electrostatic Field/Voltage Probes

   • Detect and measure electric fields or charge levels on surfaces

   • Often non-contact

Typical Applications:

• Auditing ESD-safe workstations, chairs, floors, garments

• Validating ESD compliance in manufacturing and labs

• Verifying personnel grounding via wrist straps/shoes

• Testing materials for ESD susceptibility or discharge capacity

Standards Followed:

• ANSI/ESD S20.20

• IEC 61340-5-1

• ANSI/ESD STM97.1, STM97.2

• ANSI/ESD STM11.13, STM11.11
