Characteristics and Operation of LS211 Ultrasonic Thickness Gauge
LS211 ultrasonic thickness gauge uses the ultrasonic pulse reflection principle for thickness measurement. 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 and other materials that can transmit ultrasonic waves. The instrument adopts professional timing chip design, the resolution is up to 0.001mm.
Application
In many industries, It is essential to mesure the wall thickness to confirm the condition of the material for the normal running of the items or structure safety. LS211 ultrasonic thickness meter 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.

Features
Excellent Timer chips provide fast, accurate readings
LS211 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
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
Match four kinds of probes, intelligent identification of 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 model, 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
High precision ensures LS211 can pass Chinese authoritative metrology institute
The accuracy of LS211 ultrasonic precision thickness tester can reach ± 0.05mm when testing materials 0.8-10mm thick, and the accuracy is ± 0.5% reading during 10-600mm thickness range. The gauge can pass the inspection of Chinese national authoritative metrology institute
With E-E measurement mode
When there is a coating or paint layer on the surface of the workpiece, it will make the measurement results inaccurate. 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.
Extra large storage, 999 data saved
A total of 999 data can be stored in the instrument, which can be viewed at any time, preventing data loss.
Customised storage of 18 material sound velocity
When there is no corresponding material in the instrument, the user can customise the storage of material sound velocity value. In the "Set by thickness" and "Manual input" interface each has 9 sound velocity data, which can be modified and saved at any time to meet the needs of various material thicknesses testing.

Two measurement modes: QC Mode/Statistics Mode
LS211 ultrasonic thickness tester features two measurement mode: QC mode and statistics mode
Allowing to set upper and lower limits to check the problem areas by prompting NG under the QC mode. It will count maximum, minimum and average values of data in Statistics mode

QC mode
Built-in sound velocity of multiple materials
LS211 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
Large measuring range of thickness
The instrument with standard probe can measure 0.8mm-600mm thickness of the material, to meet the measurement needs of most users.
Various materials can be measured accurately
As a non-destructive testing tool, LS211 ultrasonic thickness gauge uses dual-crystal transducer and a little amount of ultrasonic couplant to assist in detecting the thickness of substrates, able to measure the thickness of most materials, such as steel, plastics, glass, ceramics and so on.For surface measurement, the split surface of the probe should be measured perpendicular to the axis of the surface.
