Overview
The Simpson Electric 1212 is a precision analog panel meter designed for accurate DC voltage measurement in industrial and test environments. This Wide-Vue style meter provides a clear, sharp scale and self-shielding movement to deliver reliable readings regardless of external magnetic fields. The compact 1.5-inch form factor fits standard panel cutouts, making it ideal for retrofit applications and OEM equipment integration.
Key Features
- Self-Shielding Movement — Measurement accuracy is unaffected by magnetic panel mounting or external electromagnetic interference
- Wide-Vue Display — Sharp, clear scale with optimal readability across a wide viewing angle
- Rugged Construction — High-density black plastic case with clear acrylic protective pane
- Compact Form Factor — 1.5-inch (38mm) size fits standard panel openings
- Black Lance Pointer — Model 1212 features precision black lance pointer for quick, accurate readings
- Made in USA — Simpson Electric meters have been manufactured in the USA since 1927
