This unit is widely used in various precise measurement for different hardware / parts in industrial realm; one of its important application is to monitor the level of thickness-decreasing during operation of various and pressure container. Diffusely applied in manufacture fields, metal processing, and commercial inspection. The material that conduct and reflect constant sonic velocity, this product is to be applicable to used. a. Scope of application This unit is not suitable for cast iron due to its big crystalloid composition. b. How it work This unit is comprised of transimtting circuit, receiving circuit, Hi-frequency oscillator, counter, central unit processor, keypad, and moniter etc., adopting ultrasonic pulse reflect principle. Similar to light-wave measure principal, the sonic pulse occurs form the unit travels through the material being measured till reach the interface and reflects back to determine the thickness of the target material. Functions 1. Auto calibration to assure the accuracy 2. Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer 3. Make a quick adjustment for the sound velocity / thickness, and a quick recall to the stored data 4. Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not 5. 10 thickness measurement storage and recall function available, which facilitates the height work or working in wild area. 6. Sound velocity measurement 7. 12 sound velocity for different material which also adjustable Specification Display 4-digital LCD display Minimum display unit 0.1 mm Working frequency 5MHz Measuring range 1.2 to 225.0mm (steel) Minimum limit for tube measuring 20*3mm (steel) Accuracy +/- (1%H+0.1)mm H denotes the measured thickness Sound velocity range 1000 to 9999 m/s Measuring sound velocity with a given thickness measuring range:1000 to 9999 m/s, When the given thickness over 20mm, the accuracyis +/-1%; when the given thickness less than 20mm, the accuracy is+/-5% Operation temperature 0 to 40°C Power supply 3*1.5V AAA alkaline batteries Operation current Normal operation current≤50mA With Backlight turn on current≤120mA Stand-by current: ≤20uA Size 72*146*29mm Weight 202g Packing information Packing: Gift box + PP box Standard Quantity Per Carton: 20pcs Standard Carton Sise: 66.9x45.8x30.7CM Standard Carton Gross Weight: 16.5KG GM100 Thickness Meter TLEAD à¤Ã×èͧÇÑ´¤ÇÒÁË¹Ò âÅËÐ
