Advanced Measuring Height Gages
Our most precise and advanced Swiss Height Gages
Fowler Sylvac and Fowler Trimos height gages are Swiss-made precision for every level of inspection, from the shop floor to the quality lab.
Every model in the V-series is designed for ease of use, long-term reliability, and accurate, repeatable results. Whether you need a straightforward workshop gage or a full measurement station capable of 2D inspection, there's a Trimos model built for the job.
- All models feature electronically adjustable measuring force
- Diameter, centerline, height, thickness, and perpendicularity measurements across the line
- RS232 and USB data output standard; wireless available on select models
- Vast range of probe accessories and measuring inserts
- Swiss manufactured — built to perform in demanding production environments
We have 3 groups of advanced height gages
Precision shop measurement
Sylvac Hi_CAL, Trimos V3
Height, diameter, step, and centerline on a surface plate. Manual carriage, single probe holder, data output standard. No programmable routines — just fast, accurate measurements with Swiss-grade repeatability.
Extended range + air cushion
V4, V5, V6, V8
Air cushion base for glide-and-lock positioning, dual probe holders, extended accessory range. Manual carriage with optional motorized assist on V5/V6. Best for production inspection on larger or more varied part families.
Programmable measurement station
V4+, V7, V9
Touchscreen, 2D measurement, concentricity, angles and cones, SPC, programmable routines. Less a height gage than a complete measurement station standing on a surface plate. First-article inspection, lab, aerospace, medical.
Digging deeper into the capabilities of each model family
Fowler Sylvac Hi_CAL
Motorized, Bluetooth Standard
The only motorized model in the precision shop tier. Lowest measuring force in the entire lineup (0.2–0.3N) for delicate surfaces. Bluetooth standard — no dongle, no cable for data collection. Compact footprint fits tighter surface plate setups. Best pick for faster production inspections and SPC workflows where wiring is a friction point.
Pricing starts at around $6800

Trimos V3
Entry V-Series
The gateway into the Swiss Trimos V-Series. Single. manual carriage, adjustable measuring force (0.75–1.5N), 7µm BMPE, and a 40-hour battery. It delivers genuine Swiss metrology at the most accessible V-Series price. Best for shops stepping up from basic digital height gages.
Pricing starts at around $6850

Pricing starts at around $6850
Trimos V4
Air cushion, Extendable range
First model in the line that includes an air cushion base, and glide-and-lock positioning with dual probe holders. The dual-carriage extends the application range to 1,023mm (from 700mm). Wireless optional. The step up from V3 for shops needing greater range and smoother carriage movement on a busy surface plate..
Pricing starts at around $9,000

Pricing starts at around $9,000
Trimos V5
Dual-mode, Greater Height
Adds a dual-mode handwheel — switch between manual traverse and motor-assisted movement without changing tools. Range extends to 1,100mm (1,422mm with accessories). Resolution steps up to 0.0005mm. Best for shops measuring taller or more varied part families with production throughput in mind..
Pricing starts at around $9,200
Shop the V5
Pricing starts at around $9,200
Trimos V6
Greater accuracy, squareness
Same form as the V5 but with tighter resolution (0.0001mm), tighter repeatability (1µm), a tighter BMPE formula, and squareness measurement via electronic probe. The precision-first pick in the extended range tier for shops where tolerances are tight and the part mix demands more from the gage..
Pricing starts at around $12,100
Shop the V6
Pricing starts at around $12,100
Trimos V8
fine-adjustment. handwheel
The V8 features a dedicated fine-adjustment handwheel — a unique design in the V-Series that separates it from V5 and V6. Air cushion base, 0.0001mm resolution, and the same 1,427mm accessory range as the V9. Full specs pending confirmation — verify BMPE, repeatability, and wireless before publishing.
Pricing starts at around $17,500

Trimos V4+
Motorized, Bluetooth Standard
The only motorized model in the precision shop tier. Lowest measuring force in the entire lineup (0.2–0.3N) for delicate surfaces. Bluetooth standard — no dongle, no cable for data collection. Compact footprint fits tighter surface plate setups. Best pick for faster production inspections and SPC workflows where wiring is a friction point.

Trimos V7
Entry V-Series
The gateway into the Swiss Trimos V-Series. Single. manual carriage, adjustable measuring force (0.75–1.5N), 7µm BMPE, and a 40-hour battery. No air cushion, no wireless, no 2D — but it delivers genuine Swiss metrology at the most accessible V-Series price. Best for shops stepping up from basic digital height gages.
Pricing starts at around $15,100
Shop the V7
Pricing starts at around $15,100
Trimos V9
Flagship · best accuracy
The top of the Trimos lineup. Best BMPE in the series (1.2+L/1000µm), best repeatability (0.4µm), and exclusive features: contour tracking, small diameter measurement, and the full programmable station feature set. For metrology labs, aerospace, and medical shops where the gage needs to be the last variable.
