Newage NI400C Rockwell Tester | Regular & Superficial Scales | Eagle Nose

Newage Indentron NI400C Digital Rockwell Twin Tester

Model: NI400C | Type: Twin/Combination Rockwell | Serial No.: 951394

Advanced Testing Versatility

The NI400C is a "Combination" model, meaning it is engineered to perform both Regular Rockwell (60, 100, 150 kgf) and Superficial Rockwell (15, 30, 45 kgf) testing on a single platform. This dual-capability, paired with the friction-free dead-weight loading system, ensures long-term stability and repeatability that meets or exceeds ASTM E-18 standards.

Key Technical Specifications

• Testing Scales: A, B, C, D, F, G (Regular) and N, T (Superficial).
• Loading System: Precision Dead Weight for both Preload and Major Load (prevents spring-fatigue errors).
• Vertical Capacity: 10.0" (254mm).
• Throat Depth: 6.0" (152mm).
• Electronic Features: 400-Series advanced console with averaging (2–99 tests), scale conversion (ASTM E-140), roundness correction, and HI/LO tolerance settings.
• Data Output: Standard RS232 serial port for SPC software or printer integration.
• Power: 115V, Single Phase, 60 Hz.

Unique "Eagle Nose" Design

The cantilevered nose provides a 180° unobstructed view of the test area. This allows operators to test the internal diameters (ID) of rings as small as 1-1/2" and provides critical clearance for testing close to vertical shoulders or inside deep grooves.

Dealer Note

"This 1995-manufactured unit (S/N 951394) is a rugged, American-made workhorse. Unlike newer testers with delicate touchscreen components, the 400-series uses a tactile keypad and LED display designed for decades of industrial use. Whether you are testing small bearings or large aerospace castings, the NI400C remains one of the most flexible and accurate testers ever produced."
