ALLmeter Digital Table Saw Gauge
ALLmeter’s gauge centers on a high-precision digital dial indicator designed for quick, repeatable table saw alignment. The indicator offers 0.01 mm (0.0005 inch) accuracy, enabling you to dial in blade-to-fence relationships with minimal guesswork. The CNC-machined aluminum bar is 3.2 inches long and features three chutes for added rigidity, helping prevent flex during measurements. An 18 cm dial rod extension improves reach for various machines, and the six-hole pattern supports fine adjustment of the indicator location. The setup is suitable for grooves 3/4″ wide or wider, with screw-based adaptation if needed.

Buying Guide
Key factors to consider
Choose a gauge that matches your table saw’s groove width and slot size. Most common setups use 3/4″ (19 mm) slots, but some models require wider grooves; look for devices that adapt via screws or adjustable bars. Favor gauges with a rigid, CNC-machined aluminum bar to minimize flex, especially when measuring across long spans or while tightening adjustments. A reliable dial indicator with high resolution (0.001″ to 0.0005″) offers smoother, more repeatable alignments than coarse indicators.
Digital versus dial indicators
Digital indicators provide direct numeric readouts and convenient unit switching, which speeds alignment checks. Dial indicators, while sometimes slower to read, can be more forgiving in harsh workshop conditions and don’t require batteries. Many top models pair digital readouts with a sturdy bar and multiple mounting holes for flexible placement, improving repeatability across different machines.
Build quality and materials
Prioritize CNC-machined aluminum bars and hard anodized finishes for longevity. A solid three-chute or six-hole configuration improves stability and repeatability, especially when aligning multiple components. Corrosion-resistant probes and robust connections between the indicator and the bar help maintain accuracy after frequent tool changes and frequent use in dusty environments.
Installation ease and versatility
Look for units that slide cleanly into standard 3/4″ slots and offer straightforward zeroing and calibration. A self-tightening or screw-adjusted fit reduces play when grooves vary along the slot length. For users with multiple tools (bandsaw, drill press, router table), a universal or modular approach that supports different machines saves time and effort.
Safety and performance considerations
Accurate alignment minimizes blade binding, reduces burn marks, and improves cut quality. A gauge that helps maintain proper parallelism between the blade and fence also enhances safety by ensuring predictable, stable cuts. Consider gauges with ergonomic grips, integrated storage options, and accessories like hex keys to simplify adjustments on the shop floor.
