Invar Master Bar for Strain Gauge Set (U.S. Units)

Invar Master Bar

The Invar Master Bar is an essential tool for verifying the calibration of Strain Gauges, ensuring accurate and reliable measurements. Designed for compatibility with both U.S. and Metric units of measure, it is a precision instrument for professionals working with Strain Gauge Sets. Constructed from Invar nickel-iron alloy, the bar offers exceptional thermal stability due to its extremely low coefficient of thermal expansion, making it ideal for maintaining accuracy in various environmental conditions.

Threaded stainless steel inserts are strategically positioned at 2, 4, 6, 8, and 10 inches or 5, 10, 15, 20, and 25 centimeters apart, allowing users to verify the precise spacing of strain gauges. This ensures consistent and reliable calibration across a wide range of applications, from laboratory testing to field measurements.

Key Features:

• Constructed from Invar nickel-iron alloy for outstanding thermal stability and minimal thermal expansion.
