Product Overview
SPT Metrology supplies Height Gauges built for accurate vertical measurement, layout marking, and comparative inspection on granite surface plates. As a trusted Height Gauge Supplier, we serve tool rooms, metrology labs, and production floors that need a reliably stable instrument for step measurement, height comparison, and reference line scribing: work where the gauge's own stability matters as much as its readout resolution.
Stability Starts With the Base
A height gauge is only as accurate as its column and base allow it to be: a lighter, less rigid base introduces vibration and deflection that shows up as inconsistent readings, especially on fine measurement work. SPT height gauges use a rigid column paired with a heavy, well-balanced base specifically designed to stay planted on a granite surface plate without contributing measurement noise of its own.
Smooth Travel, Fine Control
The sliding carriage moves smoothly through its vertical travel, and fine adjustment mechanisms let the operator set the measuring probe or scriber precisely, the combination that separates a height gauge suited to fine inspection work from one that's only adequate for rough layout tasks.
Digital, Dial, or Vernier: Matched to Your Workflow
We supply height gauges with digital, dial, or vernier readout systems depending on the application. Digital versions offer fast zero-setting and clear displays for high-throughput inspection; dial and vernier versions remain reliable choices for shops that prefer traditional inspection practices or don't need digital data output. All three variants are built to hold their accuracy through sustained daily use, not just at initial calibration.
Built to Pair With a Reference Surface
Since a height gauge's accuracy depends entirely on the flatness of the surface it's used on, we design ours for direct compatibility with granite surface plates, ensuring the reference plane and the gauge work together rather than one undermining the other.
Why Manufacturers Choose SPT
As a trusted Height Gauge Manufacturer across Tamil Nadu and beyond, we build each gauge for the ergonomics of extended daily use as much as raw accuracy, because an inspection tool that fatigues the operator over a long shift starts producing worse readings regardless of how precise the instrument itself is.
