About Signstek Digital Ultrasonic Thickness Gauge Meter

How it work: This unit is comprised of transmitting circuit, receiving circuit, Hi-frequency oscillator, counter, central unit processor, keypad, and moniter ect., 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. Features: * Auto Calibration to assure the accuracy * Auto linear compensation: enhances the precision by correcting the non-linear accuracy of transducer. * 10 thickness measurement storage and recall function available, which facilitated the height work or working in wild area * Sound velocity measurement: with a given thickness by a sample hardware to measure the sound velocity, which avoid the further conversion or consultation of the table * 12 sound velocity for different material which also adjustable * More than 10000 times long life keys * The unit has a special memory that retains all of its setting even when the power is off Specifications: LCD digital display: 4 digits. Minimum display unit: 0.1mm. Working frequency: 5MHz. Measurement range: 1.2-225.0 mm (Steel). Minimum limit for tubes measurement: 20 x 3mm (Steel). Accuracy: ± (1% H + 0.1 mm) (H denotes the measured thickness). Sound velocity range: 1000-9999m/s. Measuring sound velocity with a given thickness. Measuring range: 1000-9999m/s. When the given thickness over 20 mm, the accuracy is ±1%; when the given thickness less than 20mm, the accuracy is ±5%. Operating temperature: 0 - 40°C (32 - 104 °F). Power supply: 3 x 1.5 AAA alkaline batteries. Package includes: 1 x Ultrasonic thickness meter 1 x Transducer (10 mm, 5 MHz) 1 x 4 mm Sample block 1 x Operating manual 3 x 1.5 AAA alkaline batteries
