The advantage video about LS213 ultrasonic thickness tester

LS213 ultrasonic thickness gauge is easy to operate and uses the principle of ultrasonic pulse reflection to test the thickness of materials. The instrument can be equipped with four types of probes: standard probe, micro-diameter probe, coarse crystal probe and high-temperature probe, and is professionally used for thickness measurement of metals (such as steel, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass and other materials that can transmit ultrasonic waves. The instrument adopts professional timing chip design, the resolution is up to 0.01mm


In many industries, It is essential to measure the wall thickness to confirm the condition of the material for the normal running of the items or structure safety. LS213 ultrasonic thickness gauge can be widely used in testing the thickness of various accessories or metallic structure to check them whether to be repaired or changed such as ships, tanks, pipes or steel structure. The gauge is applicable for petroleum, chemical, metallurgical, shipbuilding, aviation and aerospace various fields.

Ultrasonic double crystal probe

The gauge probe employs a double crystal transducer consisted of two independent crystals separated by an acoustic barrier. One crystal sends ultrasonic pulses, and another is responsible for receiving them. The probe is highly sensitive and can effectively reduce clutter, and the probe housing is made of stainless steel, which is hard and durable

With four kinds of probes, intelligent identification of the probe

The instrument can be matched with four types of probes: standard probe, micro-diameter probe, coarse crystal probe and high-temperature probe, with intelligent identification of the probe, and the instrument adapts to the display interface according to the probe type

Automatic Gain switchable

Some materials are good conductors of sound and some are not. For the latter, the meter can switch the Gain freely which is to amplify the ultrasonic signal so that the emitted pulse is accurately captured by the transducer as it propagates, and obtains accurate data

Excellent timer chips provide fast, accurate readings

LS213 ultrasonic thickness gauge calculates the material thickness by sound velocity and the time taken between the emitted pulse and the detected echo, a precision timing chip can bring the user the accurate time to get the accurate data

Coating penetration measurement mode

When there is a coating or paint layer on the surface of the workpiece, which can cause errors in the measurement results, the standard probe with penetration coating measurement mode can accurately measure the actual thickness of the substrate under the workpiece coating without removing the coating from the workpiece surface.

Bluetooth APP function

The instrument has built-in Bluetooth communication module, which can be connected to cell phone APP to achieve multiple data storage and measurement data sharing.

High precision, high resolution

The accuracy of the tester can reach ±0.05mm to ensure that it can pass the Chinese national authoritative metrology institute testing. And when testing the materials whose thickness are from 0.8mm to 10mm, its resolution is 0.01mm

Various materials can be measured

The gauge is used to measure the thickness of metallic materials (steel, iron, aluminum, copper) and non-metallic objects (ceramics, plastics and glass) and any other ultrasonic good conductors, where the other surface of the material must be parallel or coaxial to the measured surface during the test

QC Mode and Statistics Mode

LS213 ultrasonic thickness gage sets up two measurement mode: QC mode and statistics mode. The former is allowed to set upper and lower limits to check the problem areas by prompting NG or PASS. It will count maximum, minimum and average values of data in statistics mode

Provide sound velocity of multiple materials

LS213 already contains the velocities of several common metallic (such as iron, copper, aluminum) and non-metallic materials (plastics, ceramics, plexiglass) as well as other objects and the user are not required to find them separately

Comfortable grip with non-slip silicone keys

Housed in ABS plastic shell with non-slip silicone keys, LS213 ultrasonic thickness gauge has a comfortable grip and easy to operate.
