Measuring Range in Steel Pulse-Echo Mode (Pit & Flaw Detection) measures from 0.025 to 19.999 inches (0.63 to 500 millimeters). Echo-Echo Mode (Through Paint & Coatings) measures from 0.1 to 1 inch (2.54 to 25.4 millimeters). The new Dakota Ultrasonics MMX-6DL Data Logging Through Paint Ultrasonic Thickness Gauge accurately measures wall thickness and the extent of corrosion of all metals, ceramics, glass and most rigid plastics - from only one side! The MMX-6DL can be used in a Single Thickness Reading mode or in a Scan mode, where the probe is dragged over a large measuring area. The minimum thickness reading recorded during the "scan" will be displayed. The MMX-6DL incorporates a built-in memory for 1000 data points that can be separated into 10 separate "batches." The stored data can be downloaded to a serial printer or a personal computer. A Windows compatible data transfer program is supplied at no additional cost. The MMX-6DL probe is waterproof and can be submerged in water. The gauge is impact-resistant and environmentally sealed to provide trouble-free operation under the toughest field conditions.
