Static Solutions Ohm-Stat SP-101 Electrical Ground Checker / Circuit Tester / Grounding Plug — Outlet Ground Verification for ESD Wrist Strap Grounding (3-Wire 120V)
ESD Control Ground Checker Only Circuit Tester (3-Wire 120V) Banana Plug Wrist Strap Jack LED Ground/Fault Indication Made in USA
Overview

The Ohm-Stat SP-101 is a portable electrical ground checker that helps confirm outlet grounding correctness before using a receptacle as an ESD ground reference. It is designed to support personnel grounding by providing a convenient grounding plug with a banana-plug wrist strap jack and highly visible LED indicators.

In electronics manufacturing, assembly, inspection, and field service, reliable grounding helps reduce the risk of ESD events that can cause immediate failures or latent defects. SP-101 is a practical “verify then work” tool for both cleanroom and non-cleanroom workstations.

Why this ground checker matters
  • Ground-first discipline: a wrist strap only protects when the ground point is correct and trusted.
  • Fast visual confirmation: LED indicators provide quick status for correct ground or common ground faults.
  • Supports mobile work: ideal for field service kits, temporary benches, labs, and any “unknown outlet” environment.
  • Helps protect yield and reliability: reduces ESD risk during direct handling of ESD-sensitive devices and assemblies.
Typical applications
  • Electronics assembly, test, inspection, rework, and repair workstations
  • ESD Protected Areas (EPAs) needing quick verification of AC receptacle grounding
  • Cleanrooms handling electronics where low humidity can increase static generation
  • Field service / depot repair where grounding points may vary by site

ESD Education Ground Integrity Personnel Grounding Compliance Verification
The ESD reality: a wrist strap is only as good as the ground you connect to

ESD programs are built around one practical idea: keep people, tools, and sensitive devices at the same electrical potential so discharge events are minimized. In many operations, the wrist strap system is the primary control for seated handling of ESD-sensitive items. If the operator’s ground point is wrong, uncertain, or miswired, the strap becomes a false sense of security.

Why verification is emphasized in ESD guidance

ESD controls drift. Cords fatigue, connection points loosen, contamination builds on contact surfaces, and facilities changes can introduce wiring errors. This is why ESD compliance guidance focuses on verification and troubleshooting as ongoing disciplines, not one-time setup tasks.

Technical Vault takeaway: If you cannot verify your grounding path, you cannot rely on it. Quick checks before handling high-value electronics reduce “unknowns.”

Where SP-101 fits: outlet grounding confirmation + wrist strap connection point

The Ohm-Stat SP-101 is designed for practical, repeatable use: it checks wiring faults on 3-wire, 120V circuits, provides highly visible LED indicators, and includes a banana jack so a banana-plug wrist strap can be connected at the receptacle. Each unit contains 1 ground checker, making it a lean tool for benches, labs, and field kits.

Cleanroom + electronics note

Low humidity and synthetic consumables common in controlled environments can increase static generation. If electronics are involved, grounding integrity is a direct yield and reliability control.

How to use SP-101 in a disciplined workflow
  1. Verify the receptacle first: plug in SP-101 and confirm correct wiring/ground status before trusting the outlet as a ground reference.
  2. Connect the strap correctly: ensure the wristband has solid skin contact; connect via the banana jack.
  3. Follow your ESD program verification plan: many programs verify wrist straps routinely (often daily if continuous monitors are not used).
  4. Escalate failures: if the outlet indicates a fault, do not use it for ESD grounding—move to an approved point and notify facilities/EHS per site procedure.
Why teams buy SP-101 from SOSCleanroom
  • Program standardization: issuing a consistent verification tool reduces “DIY grounding” workarounds that create escapes.
  • Auto-Ship support: keep ESD essentials in stock so production and service teams do not pause for compliance basics.
  • One-cart procurement: ESD controls, facility supplies, and cleanroom consumables in one purchasing flow.
  • Education-first enablement: Technical Vault guidance helps translate “ESD requirements” into consistent operator behavior.
