Product Description Handheld LCD Ultrasonic Thickness Gauge for Steel, Metal and Aluminum - This ultrasonic thickness gauge is a smart handheld product that adopts ultrasonic measurement principle and is controlled by a microprocessor. It enables fast and precise thickness measurements for most industrial materials. - The device has a wide measuring range of 1.0 to 200.00 mm (0.05 to 8 inches) with precise measurements. In addition, the gauge can measure 11 types of materials including steel, cast iron, aluminum, gunmetal, brass, zinc, quartz glass, polyethylene, PVC, gray cast iron and ductile iron. - This device is widely used for various precise measurements of different hardware/parts in the industrial field. One of its important applications is monitoring the thickness decrease during the operation of various pressure vessels. - It is widely used in the fields of manufacturing, metal processing and commercial inspection. This product can be used for materials that conduct and reflect a constant speed of sound. Features: - Automatic calibration to ensure accuracy - Automatic linear compensation: This advanced software program improves precision by correcting the non-linear accuracy of the transducer - High resolution measurement - Use the buttons to select the material code to be measured - Automatic zero calibration of the probe to correct system errors - Capture the value of the minimum thickness - Coupling and low battery status indication - Automatic sleep and power off function to save battery life - User-friendly design, compact and portable, can be used in harsh environments Specifications: - LCD digital display: 4 digits - Resolution: 0.1mm - Working principle: ULTRASONIC - Measuring range: 1.0 ~ 245.0mm, 0.05-8inch (Steel) - Accuracy: (0.5%H + 0.1mm) depends on Materials and Conditions - Units: Metric/Imperial unit selectable - Operating Temperature: 0 ~ 45 C (32 ~ 104 F) - Power Supply: 4 x 1.5 AAA alkaline batteries (not included) - Battery Indicator: Low battery indicator - Item Dimensions: Approx. 72 (L) x 146 (W) x 29 (H) mm (2.83 x 5.75 x 1.14 inches) - Item Weight: Approx. 202 g (7.12 oz) Material Code: - Aluminum: Cd03 - Brass: Cd05 - Cast Iron: C02 - Gray Cast Iron: Cd010 - Ductile Iron: Cd011 - Polyethylene: Cd08 - PVC: Cd09 - Quartz Glass: Cd07 - Red Copper: Cd04 - Steel: Cd01 - Zinc: Cd06 Package Contents: - 1 x Ultrasonic Thickness Gauge (Batteries not included) - 1 x Transducer (8mm) - 1 x User Manual Note: Do not impact the device during use.
