UNI-T UT343D Coating Thickness Gauge

The UNI-T UT343D is an advanced gauge designed to accurately measure the thickness of paint and other protective coatings on metal surfaces - both steel and aluminum. The device is characterized by a fast measurement function, color TFT screen, computer connectivity and many intelligent functions.
The UT343D measures the thickness of coatings in the range from 0 to 1250 µm with a resolution of 0.1 µm (in the range of 0-99.9 µm) and 1 µm (for values ​​above 100 µm). The accuracy is ±(3%H + 1) µm, so you can get reliable results even with very thin layers. You can perform measurements in single or continuous mode, and additional Max/Min/Avg functions help you analyze measurement series.
A unique function of the UT343D is the Quick Test mode, which allows you to determine the tolerance limit of the coating thickness. If the measured value falls within the specified range, the device indicates this with a 3-color LED and a sound signal. This solution is particularly useful in the paint, sheet metal or quality control industries.
The device is equipped with a 2-inch TFT color display (320 × 240 pixels), with brightness control and an automatic rotation function, which ensures comfortable handling regardless of lighting conditions and working position. In addition, a low battery indicator lets you know when the batteries need to be replaced. The measurement data can be stored in the device's memory (up to 500 groups), then transferred to a computer via USB and analyzed using the dedicated software.
