High Precision Ultrasonic Thickness Gauge - DW-300

Unit Price: US $1499.00

DW-300 is for high precision, high resolution and ultra fine thickness measurements. It uses the most advanced microprocessor and ultrasonic technology to offer users many outstanding features. It presents highly stable and repeatable reading, high accuracy and resolution (up to 0.001 mm or 0.0001 inch) and ability for measuring ultra thin sample (as low as 0.15mm or 0.006 inch). It also offers a compact, comfortable and durable structure for hand-holding, simple to use through the menu, multiple language selection, low power consumption (with two normal or rechargeable AA batteries). These features along with its high quality probe make DW-300 unequalled in its performance as well as its value!

DW-300 is manufactured under the strict quality control guidelines established by ISO 9001: 2000 Standards. Its quality is insured by our return policy and full-coverage warranty.
