What the product record supports.
Four confirmed points: material, measurement, readout and power. Full values are in the specification table below.
Measurement
ultrasonic · 0.9-300mm(steel) · ±(1%H+0.1)mm

Power & body
3.7V lithium battery（2000mAH） · 141×69×27mm / 162g（excluding probe）
In practice
Where the DR83A is used
A straightforward rechargeable gauge for routine wall-thickness checks on pipes, boilers, pressure vessels and steel plate — 0.9 to 300 mm on steel.
01
Routine wall surveys
0.9–300 mm (steel)
Check remaining wall thickness on process piping, boiler shells and pressure equipment, point by point.
The surface must be accessible: clear the coating and apply couplant at each measurement point.
02
Straightforward readouts
0.1 mm resolution
Velocity, thickness and max / avg / min grouping show on the 2.8-inch colour screen for quick surveys.
Accuracy is ±(1%H+0.1) mm — suited to routine surveys, not precision tolerance checks.

Rechargeable everyday kit
3.7 V 2000 mAh
300
mm · max steel range
The built-in 2000 mAh cell charges directly, and the 162 g body travels easily between job sites.
Standard probe is rated −10 to +50 °C; a high-temperature probe covers media below 300 °C.
Pulse-echo · 0.9–300 mm (steel) · 0.1 mm resolutionDR83A · Ultrasonic wall thickness gauge
Where it stopsPulse-echo needs couplant on bare metal, so painted points must be cleared locally before reading. For measuring through the coating see the DR87A; for 0.01 mm resolution see the DR86A.
