Ultrasonic Thickness Gauge NOVOTEST UT-2A (A-Scan)
Industrial inspection equipment
Overview
The NOVOTEST UT-2A (A-Scan) Ultrasonic Thickness Gauge is designed for industrial thickness measurement where waveform analysis, probe flexibility and detailed inspection control are important. Its A-scan capability allows trained inspection personnel to examine ultrasonic signals in addition to obtaining digital thickness readings. This makes the instrument relevant to inspection applications that require more than basic digital thickness measurement. The UT-2A supports A-scan, B-scan, digital, manual and thickness-limit control modes. Its published specifications include a measurement range of approximately 0.4–1,500 mm in steel, depending on the selected probe and material characteristics. The instrument offers a 3.5-inch colour display, measurement resolution of 0.01 mm and a built-in rechargeable battery. It also supports multiple measurement methods, including echo, echo-echo and peak-to-peak, depending on the selected configuration. The UT-2A is suitable for consideration by Indian NDT inspection agencies, manufacturing facilities, fabrication contractors and industrial maintenance teams. It can support thickness measurements on suitable metal components, including pipes, plates, tanks and other structures where access is available. Its waveform display and multiple operating modes help trained users assess measurement conditions and select appropriate inspection settings. Buyers considering the NOVOTEST UT-2A should evaluate the required probe frequency, material characteristics, thickness range and inspection procedure. Optional probes, including through-coating and high-temperature configurations, may be relevant to particular applications. The required calibration blocks, couplant, data-transfer options and reporting workflow should also be reviewed before finalising the equipment configuration.
