SIMA AS840 Ultrasonic Thickness Gauge is an intelligent hand-held ultrasonic Thickness Gauge , which is controlled by a microprocessor and uses the principle of ultrasonic measurement to measure the thickness and sound velocity of various materials quickly, without damage, and accurately. This instrument can be used for accurate measurement of various materials or parts in the field of industrial production. Another important aspect is that it can monitor various pipelines and pressure vessels in production equipment, and monitor their thinning after being corroded during use. degree. It can also be widely used in detection fields such as manufacturing industry, metal processing industry, and commodity inspection. All kinds of materials that can transmit ultrasonic waves at a constant speed and can distinguish the reflected waves generated on the back are suitable for this instrument.
Metals, plastics, ceramics, glass and any other good conductors of ultrasonic waves can use this instrument to measure thickness as long as there are two parallel surfaces, such as aluminum, copper, gold, resin, water, glycerin, etc. Cast iron is not suitable for using this instrument because of its internal crystal grains are too coarse!

Automatic calibration of the zero point can correct the system error;
Linear automatic compensation, using computer software to adjust the probe non-linearity in the whole range
Linear errors are corrected to improve accuracy.
Use the up and down keys to quickly query and adjust the sound velocity and thickness values;
Coupling status prompt: By observing the stable state of the coupling flag, you can know whether the coupling is normal;
Storage function: ten thickness values can be stored, and the data will not be lost after shutdown, which brings convenience to high-altitude and field work;
Sound velocity measurement and storage sound velocity function: directly measure the sound velocity according to the thickness of the sample, avoiding the trouble of table lookup or conversion; 12 sound velocity values can be stored;
Low battery reminder function: If the battery is low, the low battery will prompt the user to replace the battery;
Manual and automatic shutdown: In the power-on state, press the [ ] key to shut down; it will automatically shut down after 2 minutes without any working equipment.
