This ultrasonic thickness gauge is an intelligent handhold product, which adopts ultrasonic measuring principle, and is controlled by -processor, provides quick and precise measurement of thickness for most of industrial material.<br> This unit is widely used in precise measurement for different hardware / parts in industrial ; one of important application is to monitor the level of thickness-de-creasing during operation of and pressure container.<br> Diffusely applied in manufacture fields, metal processing, and commercial inspection. The material that conduct and constant sonic , this product is to be applicable to used.<br> Auto calibration to assure the accuracy. Auto linear compensation: this advanced software progr- am enhances the precision by correcting the non-linear accuracy of transducer.<br> Use and keys to make a quick adjustment for the so- und /thickness,and a quick recall to the stored data.<br> <br> Coupling status indication: Observing the coupling to learn if the coupling is accomplished or not.<br> 10 thickness measurement storage and recall function available, which facilitates the height work or working in area.<br> Sound measurement: With a given thickness by a sample hardware to measure the sound , which avoid the further conversion or consultation of the table.<br> 12 sound for different material which also adjus- table.<br> Low battery indication<br> Auto power off mode designed to conserve battery life. More than 10000 long lift keys.<br> The unit has a memory that retains all of setting even when the power is off.<br> Measuring range: 1.2~225mm<br> Accuracy: (1%H+0.1)mm<br> Resolution: 0.1mm<br> Sound Range: 1000~9999m/s<br> Working Frequency: 5MHZ<br> Minimun Limit For Tube Measuring: 20 x 3mm(steel)Auto Calibration to Assure the Accuracy: <br> Data /Recall/Delate Function: <br> Sound Mearsurement: <br> Low Battery Indication: <br> Auto Power Off: <br> LCD Backlight Display: <br> Thickness Measurement Storage: <br> Unit Size: 80 x 38 x 150mm<br> Power Supply: 3 x 1.5V AAA Batteries (Not Included)<br> color:As shown<br> Material:plastic<br> <br> Package Contents:<br> 1 x Ultrasonic thickness meter GM100<br> 1 x Transducer(10mm 5MHz )<br> 1 x 50ml Coupling agent(Not included)<br> 2 x 4mm Sample block<br> <br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
