Fowler Dial Indicator Gauge

Fowler Dial Indicator Gauges: Shop-Grade Precision Since 1946

Fowler High Precision has been a cornerstone of the metrology world since its founding in 1946, and its dial indicator gauges represent some of the most trusted precision measurement instruments available to machinists, quality control technicians, and automotive professionals alike. Since 1946, Fowler High Precision has been a leading supplier of precision measurement instruments and electronic gauges ideal for quality control and inspection, based in Newton, Massachusetts, striving to provide excellent products at competitive prices.

A Dial Indicator for Every Application

Fowler High Precision has one of the most diverse selections of dial indicators available in the US today. Whether you need a straightforward mechanical gauge for surface runout checks or a robust shockproof unit for heavy-shop environments, Fowler's lineup covers the spectrum. Fowler offers AGD1, AGD2, and AGD3 classifications for dial indicators, allowing users to select the right gauge group for their specific bore, range, and mounting requirements. This adherence to American Gauge Design (AGD) standards ensures compatibility with standard accessories and magnetic base setups across the board.

For demanding shop environments, the Fowler Premium IP54 Shockproof Dial Indicator raises the bar significantly. It includes NIST certification, both center lug back and flat back mounting options, a steel housing, sealed plunger, dustcap, bezel lock, a carbide contact point, and a 0–100 dial reading with revolution counter, available in a 1" range with 0.001" graduation. This combination of sealing and certification makes it particularly well-suited for production floor environments where coolant splash and vibration are common concerns.

Built-In Quality: Materials and Construction

Fowler doesn't cut corners on materials. Spindle racks and contact points are made of hardened stainless steel for long wear, cases are forged brass with a satin-chrome finish, and gear wheels are hard brass — a construction philosophy that promotes longevity and consistent measurement accuracy over thousands of cycles. Many models also feature tolerance hands and revolution counters, giving technicians immediate visual feedback without manual calculation.

The Premium White Series dial indicators further exemplify Fowler's attention to user needs. These popular AGD 2 series gauges come with various graduations and ranges, include tolerance markers, feature a solid steel housing, a carbide contact point, and include an NIST certificate of calibration. That NIST traceability is especially important for shops operating under ISO or AS9100 quality systems, where documented calibration is a requirement, not a luxury.

Combo Kits and Magnetic Base Sets

Fowler also offers complete dial indicator combo kits that pair gauges with precision magnetic bases — ideal for professionals who want a fully matched, ready-to-use setup right out of the box. These kits include a 1" indicator and magnetic base with rods, swivel clamp, and case; the 2-1/4" diameter 0.001" indicator features a satin chrome finish, tolerance hands, lug back, and a revolution counter. All exposed metal is finished in anodized black for corrosion resistance, and the kit is furnished in a shop-hardened case.
