Overview
The Triplett 220-GL panel meter is a precision analog instrument designed for DC milliampere measurement in the 0–200 DCMA range. Standard indication accuracy of ±2% for AC & DC ensures reliable readings in industrial control, test, and measurement applications. This two-stud mount meter is a proven choice for facility maintenance, equipment diagnostics, and quality assurance tasks requiring accurate current monitoring.
Key Features
- Taut band suspension standard for sensitive ranges — reduces friction and improves response time
- Two stud mounting — simple, secure installation in standard panel cutouts
- Internal resistance (0–200 DCMA): 360 Ω — optimized for low-impedance circuits
- Durable construction with clear, easy-to-read scale markings
- Compact 2.5″ front face — fits tight panel spaces
