Max Force 250Kgf Touch Screen Auto Turret Hardness
Tester CHBVST-250Z Support Brinell Vickers
Brief Introduction:
The iqualitrol new CHBVST-250Z was designed and manufactured according to standards GB/T 4340.2-2025, ISO 6507-2, ASTM E384, GB/T 231.2, JJG150-2005 verification procedures, and standard EN ISO 6506, while also accommodating both Brinell and Vickers measurements, greatly improving practicality.
CHBVST-250Z adopts a closed-loop load control system, ensuring high accuracy of test force and excellent repeatability and stability of readings.
Significant enhancements have been made in terms of optical performance as well as structural stability and durability, providing good reliability, operability, and repeatability. It is an ideal instrument for testing Brinell and Vickers hardness.
CHBVST-250Z utilizes programmed control, a high-magnification optical measurement system, and an optical dual-channel structure, along with new technologies such as photoelectric and optocoupler sensors. Through touch screen operation, it can directly measure the indentation length, display hardness values on the screen, convert scales, set test force, maintain test force time, and record the number of measurements.
