In practice

Where the DR89S is used

Built for thin materials: automotive sheet metal and other light-gauge walls from 0.15 mm, where ordinary thickness gauges bottom out.

DR89S thin-material ultrasonic thickness gauge with single-crystal probe

01

Automotive sheet metal

From 0.15 mm

Measure body panels and other light-gauge stock with the standard 15P6 single-crystal probe.

The dual-crystal probe (optional) is required for the extended range and coarse surfaces.

02

Precision on thin walls

±(0.01+0.3%H) mm

A 0.001 mm resolution mode resolves very small differences on foil, sheet and panel work.

0.001 mm resolution applies to the single-crystal setup; calibrate velocity to the actual material.

03

Light body, AAA power

3 × AAA batteries

0.15

mm · minimum thickness

The 125 g body with 2.3-inch colour screen is easy to handle around panels and narrow parts.

Runs on three AAA alkaline cells — carry spares for long shifts; no built-in rechargeable pack.

Where it stopsThin-material work needs a smooth, accessible surface and couplant; readings reflect substrate thickness, not coating. For through-coating measurement see the DR87A.
