Shipping Policy : 1.Battery and Liquid not included during the shipping.2.WE ship the products by DHL ,FEDEX ,UPS or other express etc.Features: * Wide Measuring Range and high resolution. With high power emission and broad band receiving sensitivity, the gauge can match probes of different frequencies. That makes it easy to measure the rough surface, even cast iron. It is widely used in almost all kinds of industries. * 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 & fast measuring time. * Using the latest high performance and low power consumption microprocessor technology. * Automatic memory material code and sound velocity value, convenient to use. * Use USB/RS-232 data output to connect with PC. * Provide Bluetooth data output choice.
