Description
Description
The Linshang LS211 ultrasonic thickness gauge measures material thickness from one accessible side using a dual-element probe. With the standard 5 MHz, 10 mm probe, its range is 0.8–600 mm on 45# steel, with display resolution changing according to the measured thickness.
Main unit with standard probe
This LS211 package includes the main unit and standard 5 MHz, 10 mm dual-element probe.
The compatible 7 MHz PT-06 accessory probe covers 0.75–80 mm on 45# steel for smaller measuring areas. The 2 MHz ZT-12 and 5 MHz GT-12 probes cover 3–200 mm on 45# steel for coarse-grained materials and elevated-temperature workpieces respectively. Their ranges and operating conditions differ from the standard probe.

Standard-probe measuring specifications

Sound velocity, coupling and coated surfaces
Set the sound velocity for the material, or determine it from a known-thickness piece of the same material. Apply couplant, hold the probe flat and wait for stable coupling. The opposite surface must be parallel or coaxial with the test surface. Steel, aluminum, glass, ceramics and suitable plastics require an adequate ultrasonic signal and the correct velocity setting.
With the standard probe, E-E mode uses successive back-wall echoes to measure the substrate beneath a coating. Its stated limits are 0.2–2.5 mm coating thickness and 4–60 mm substrate thickness on 45# steel. Enable E-E mode for that application; the full normal measuring range does not apply in this mode. It reports substrate thickness rather than a separate coating thickness.
Save and review a measurement series
Bluetooth connects the gauge to the UT and HL app for Android 7.0 or later. Dedicated PC software supports measurement data handling and export. The instrument can store up to 999 readings; statistics mode shows maximum, minimum and average values, while QC mode compares readings with user-set limits.
Automatic gain adjusts the received signal to the material and thickness. Perform reference calibration with the built-in reference block, and clean the probe and block after use. Display resolution is the smallest displayed increment, not an accuracy guarantee for every material or probe.
