Chemical equipment, boilers, oil storage tanks, and more in industries of petroleum, ship building, power station and machine manufacturing. It uses the latest high performance and low power consumption microprocessor technology. Applicable to measure the thickness of many materials. E.g. Steel. Cast iron. Aluminum. Red copper. Brass. Zinc. Quartz glass. Polyethylene, PVC. Gray cast iron. Nodular cast iron. Used the exclusive Micro-computer LSI circuit and crystal time base to offer high accuracy measurement. With high power of emission and broad of receiving sensitivity. The gauge can match probes of different frequencies. That makes it easy to measure the rough surface, even cast iron. Bidirectional measurement. For materials within measurement range, thickness is measurable with know velocity, Conversely velocity is measurable with know thickness. Automatic memory material code and sound velocity value.
