Precision A-Scan Ultrasonic Thickness Gauge GUTA10

1, Overview

1.1 About the GUTA10

GUTA10 is portable, digital, handheld thickness gauge and it is specifically designed to measure the remaining wall thickness of primarily steel structures.

*A scan and B scan both

*Chargeable batteries

*Small, easy to hold, ergonomic, custom molded, durable case

*Automatic zero capability

*Gain boost

*Multiple dual and single element transducer options.

The GUTA10 is a wide-range model consisting of the most commonly used features in a thickness gauge not requiring a data logger. This model offers a simple user interface packaged in the same custom molded high-density plastic case and it offers gain adjustment, beep alarm. Besides, GUTA10 contains a top function which is Echo-to-Echo.

1.2 Principle and application

This instrument is a portable industrial non-destruction measurement instrument under ultrasonic measurement principle, suitable for measuring of thickness of materials in which ultrasonic can transmit at certain speed and reflect from the back.

It measures various sheet and machined parts accurately, and can monitor corrosion thickness decrease of manufacture equipment such as various pipes and pressure vessels during usage, suitable for lab and engineering field. This device can be used for quality control in manufacture, steel metallurgy, metal working and chemical etc, as well as for on-line security inspection and life evaluation in fields of aero, railway and boiler pressure vessel etc. It is a necessary instrument for non-destruction measurement industry.

This device is an ultrasonic thickness gauge with wave (A-scan) display. Its features for thickness measurement are that the echo is helpful for better measurement, avoid measurement error relating to materials, such as error due to crack or non-uniformity in practical measurement. We often need to measure thickness of materials with coatings (such as: painting and PVC coating etc). For precise measurement, it is often necessary to remove the coating, otherwise the measuring result may contain “equivalent thickness” which is times of the thickness of coating. In fact, in most cases, the corrosion-proof layer can’t be removed, and thickness gauge is calibrated on parts with coating, resulting in large measurement error. A-scan wave display ultrasonic thickness gauge can penetrate the coating and measure wall thickness of parts accurately by multi echoes.
