Scales and Instruments
We manufacture scales suited for what you need to measure, from automobiles, bicycles, to small aircraft. We also provide a variety of instruments used for wind tunnel testing.
Modular Scale for Automobiles: SLIM BALANCE
With its slim 30cm thick frame and ability to produce a high precision reading (±0.05% reading), this automobile scale is built for tight spaces. Its modular design allows it to be put together piece-by-piece with a manual lifter instead of a forklift. This new design came to life with the help of scale manufacturer Yamato Scale and our trading company Nishiyama.
We also provide wind tunnel tests using this scale at the Fuji Aero Performance Center in Numazu, Shizuoka.

Bicycle Measuring Table
A table with a scale built for measuring drag of road bicycles. Designed for use with the Aero Optim wind tunnel units, it features a slim, portable build. Supports are currently compatible with thru-axles and quick-release axles.
Wind tunnel testing using this scale is available at the Fuji Aero Performance Center in Numazu, Shizuoka.

Pitot Tubes
We manufacture and calibrate pitot tubes of various types, including straight-type, JIS-type, and 5-hole-type.
Ultrasonic Anemometer (ULSA PRO)
This product is a result of a joint-venture development between Japan Wind Tunnel Mfg. and STRATOVISION.
ULSA PRO is made to be an upgrade of the compact and light-weight ultrasonic anemometer ULSA BASIC/M5B series, with increased maximum measurable wind speed (50m/s), added water-resistance (IPX6), and improved compatibility wind flows from an angle (up to ±20°) while maintaining high precision.
In this joint-venture development, Japan Wind Tunnel Mfg. provided fluid analysis and support using a high speed (50m/s range) wind tunnel, while STRATOVISION provided design for the ULSA PRO’s electronics and software.
Boundary Layer Probe
We provide custom-built probe arrays for boundary layer measurement.
