Tokyo Keiki Portable Ultrasonic Thickness Gauge UTM-210
The Tokyo Keiki UTM-210 is a high-precision, pocketable ultrasonic thickness gauge built for inspectors and engineers who need finer resolution and reliable field performance. Drawing on Tokyo Keiki’s long history of portable ultrasonic gauges, the UTM-210 raises measurement fidelity with 1/100 mm resolution while keeping the compact, ergonomic body and data-handling features that make the UTM series easy to use on site.
Key features (Tokyo Keiki Portable Ultrasonic Thickness Gauge UTM-210)
-
High-precision measurement to 0.01 mm (1/100 mm) — with values ≥ 80.1 mm displayed at 0.1 mm.
-
Fast, steady readout (approx. 0.75 s per reading; ~1.3 readings/sec or more).
-
Ergonomic, grip-focused housing and large keypad/display for comfortable one-handed operation.
-
Hold function that keeps the reading on screen when the probe is lifted from the test surface.
-
Built-in data logger stores up to 1,000 time-stamped records; exportable to a PC over the supplied USB cable for easy reporting.
-
Wide sound-velocity setting range (1000–19,999 m/s) and automatic sensitivity adjustment for quick setup.
-
Long battery life from a single AA alkaline cell — approx. 40+ hours continuous use.
-
Capable of measuring small-diameter pipes and thin materials when used with the appropriate optional probe;
several optional probes and special probes for small pipes / high-temperature use are available.

Why choose the UTM-210?
If your inspections require sub-0.1 mm accuracy (for example, precision corrosion monitoring, thin-material checks or high-resolution R&D tasks), the UTM-210 provides that extra precision while remaining pocketable and field-friendly. Its data-logging and USB export make it simple to collect and integrate measurement data into reports, and optional probes extend the instrument’s usefulness to small pipes and high-temperature surfaces.
