Product Description Made In China Ultrasonic Thickness Gauge With A-Scan Snapshot LM-4 is a new generation thickness gauge, Breakthrough technology provides a thickness gauge with better performance for the same budget. It greatly improves the performance of previous ultrasonic thickness gauges and has better measurement stability and repeatability. It is widely used for wall thickness measurement of pipelines, pressure vessels and storage tanks in petrochemical, electric power, ships and manufacturing industries.Feature:1. Economical full digital thickness gauge All-digital thickness gauge needs to convert analog ultrasonic signals into digital signals, and then process the digital signals to obtain high-performance thickness measurement capability. The A-scan snapshot function, zero-crossing measurement technology and high resolution of LM-4 series are all based on all-digital technology. 2. The innovative A-scan snapshot function LM-4 is the first product in the same file to provide A scan waveform display function. Acoustic non-ultrasonic wave is no longer an abstract concept that cannot be seen or touched. Users can directly see the ultrasonic signal waveform on the screen, which is used to verify whether the thickness reading is correct, analyze the cause of the problem, and help users find a solution to the problem.3. Adopt breakthrough zero-crossing measurement technology Based on all-digital technology and zero-crossing measurement technology, the thickness measurement value is not affected by echo intensity, material attenuation coefficient, gain and gate height, and has high measurement stability and reliability. 4. The function of penetrating the coating(1) Zero-free calibration; (2) high stability, the measured value is not affected by probe pressure, coupling layer thickness and dust stains on the surface of the workpiece; (3) Zero drift. 5. More practical functions (1) Gain: adjustable for high, medium and low gears; (2) Alarm mode: dynamically change thickness reading color during alarm; (3) Difference/Reduction Rate: The difference mode shows the difference between the measured thickness and the preset thickness. The reduction rate is the percentage of thickness reduction calculated and displayed after the material is thinned. The typical application is to measure the metal material thinned due to bending. (4) Maximum/Minimum Capture: The current thickness value, minimum thickness value and maximum thickness value are simultaneously displayed on the screen.Specification:ModelLM-4DMeasuring range0.65-508 mm (0.025 - 20.00 inches) depends on the probe used, the material to be tested, and the surface condition.Penetration coating functionYESWorking principleUltrasonic Pulse Echo Method Using Double Crystal ProbeLower limit of pipe measurement (steel)φ 20 mm * 3.0 mm (PT08 probe); φ 15 mm * 2.0 mm (small diameter tube probe)Measurement resolution0.01 or 0.1mm (0.001 or 0.01in)UnitMillimeters or inchesDisplay2.4QVGA (320×240) color OLED screen with contrast ratio of 10000:1Repeatability±0.05mmProbe calibrationOne-point calibration, two-point calibrationMeasurement error0.05 mm (less than 10 mm) (0.5% h+0.01) (more than 10 mm) Note: h is the thickness of the measured objectThe measurement update rate4HZ, 8HZ and 16HZ per second are optional.The sound speed range of the material500-9999m/s,0.0179-0.3937in/usStorage functionStore100,000 thickness valuesAlarm functionThe maximum/minimum alarm, alarm dynamically change the thickness reading colorGainHigh, Medium and Low Gear AdjustableDisplay modeThickness value mode, minimum/maximum capture mode, difference/reduction rate modeV path correctionAutomatic A-range correction to compensate nonlinearity of bimorph probeLanguageChinese, English, Japanese, German and French are availablePower supplytwo AA batteriesOperating timeTwo AA batteries for more than 35 hoursAutomatically shut downOptional 5, 10, 20 minutes after no operation automatically shut down, or only manually shut downWorking temperature-10oC ~+50oC, with special requirements up to -20oCSize153*76*37mmWeight280g (including battery)Standard configurationThickness gauge host, standard probe, instrument box, two alkaline batteries, coupling agent, operation manual, certificate of approval and packing listOptional accessoriesRubber jacket; A variety of selectable probes; Step test block for calibration; Coupling agent and high temperature coupling agent Configuration listMainframe1Coupling agent1Probe1Battery2Packing document1Instrument seal box1Data line1(only LM-4DL)Communication software1(only LM-4DL)Note: If send it by air, not including batteries, it's an empty bottle for Coupling agent.
