Description

This precision height comparison bench is a dedicated metrology fixture that provides an ultra-flat, thermally stable reference plane for dimensional inspection. It eliminates measurement errors caused by uneven workbench surfaces, ensuring highly repeatable and reliable inspection data for workpiece height verification, batch size comparison and measuring instrument calibration. It is widely deployed in metrology laboratories, quality control stations, precision mold making and high-end component production lines as a fundamental tool for precision dimensional quality control.

Dual Premium Measuring Surface Options

Two high-performance surface materials are available to match different application requirements:

Ceramic measuring surface (H-F1940) : High-density advanced ceramic with extreme hardness, scratch resistance and corrosion resistance. Its ultra-low thermal expansion coefficient maintains dimensional stability under temperature fluctuations, making it ideal for high-precision comparison measurement in constant-temperature metrology laboratories.
Granite measuring surface (H-F1920) : Natural high-density granite with excellent inherent vibration damping performance and exceptional long-term dimensional stability. The working surface is precision lapped to ultra-high flatness, resistant to wear and deformation, suitable for heavy daily workshop inspection and large workpiece measurement.

All measuring surfaces undergo 100% factory flatness calibration and are supplied with an official inspection certificate, ensuring traceable measurement accuracy.

Heavy-Duty Stable Base & Adjustable Support Structure

The heavy base design delivers outstanding vibration absorption, effectively isolating ambient vibration from production equipment and eliminating reading fluctuations during micron-level precision measurement. The 180mm high rigid metal column paired with an 80mm adjustable support arm allows smooth vertical positioning and firm locking, adapting to workpieces of different heights and various measurement setups.
Universal Φ8mm Standard Collet

Adopts industry-standard Φ8mm clamping interface, fully compatible with all mainstream mechanical dial indicators, digital dial gauges, lever test indicators and displacement sensors on the market. The knurled locking knob enables quick installation and stable clamping, with no loosening during long-hour continuous measurement.
Low-Maintenance & Customizable Design

Both ceramic and granite materials are naturally corrosion-resistant and scratch-resistant, requiring minimal daily maintenance while retaining accuracy for decades of service. Custom laser logo service is available to meet brand display needs for enterprises and distributors.
Retail-Oriented Packaging & Global Shipping Support

Each unit is packed in an independent shockproof export carton, supplied with a factory flatness inspection certificate and full English operation manual. Standardized retail packaging is suitable for international express delivery, with clear packing dimensions and weight data for fast customs clearance.
