Overview
The DONGRU DR87S Ultrasonic Thickness Gauge is a Portable thickness gauge designed with a high-speed processor and a highly integrated chip using ultrasonic measurement principles. It provides nondestructive, fast and accurate measurement of thickness and Speed of sound of a variety of materials. It is suitable for metals, quartz, Glass, plastics and other materials. It has two modes of standard measurement and penetrating coating measurement. Direct measurement of substrate thickness without sanding paints.
Features
1. Suitable for thickness measurement of almost all materials, such as metal, Glass, plastic and other materials
2. Direct measurement of substrate thickness without paints coating on sanding metal surfaces
3. The instrument is exquisite, compact and intuitive, with a 2.3-inch large color screen display. Handheld is easy to carry and suitable for on-site testing
4. Measurement mode: Standard mode/Penetration mode
5. Measurement accuracy, Measurement range, a standard Probe complete full range
6. Chinese and English bilingual version
7. Bluetooth interconnection data transmission function (suitable for Bluetooth version thickness gauge)
8. Adjustment: Probe standard block calibrated, Speed of sound calibrated, Speed of sound can be calculated by known thickness, and the value can be adjusted freely through the arrow keys
9. Manual shutdown and automatic shutdown, users can choose at will
10. Built-in 7 common materials Speed of sound, and can be edited for user convenience
11. Humanized data storage mode: large-capacity storage, can save data in groups, store 10 sets of data, 200 data in each group, a total of 2000 data, manual storage is conducive to result analysis
12. Multi-Probe used in combination, high temperature environment measurement can be optionally equipped with high temperature Probe high temperature resistance (300 ℃)
Principle
The thickness gauge uses the ultrasonic Measurement principle to penetrate the object at a constant speed and generate reflected waves. After the surface of the measured object is coated with a coupling agent, the Probe is placed on the contact surface on the side of the measured object to quickly and accurately measure the thickness.
Applications
Thickness measurement of metal, quartz, Glass, plastic
Steps
1. Apply a coupling agent to the surface of the tested object
2. Place the Probe on the contact surface on the side of the object being tested
3. Instrument automatic measurement and display thickness
Notice
• Coating thickness should be less than 2mm
• Ambient Temperature 0 ℃ -50 ℃
• Operating Relative Humidity 20~ 90% RH
• Instrument calibrating and sound speed calibrating are required before use
• Pay attention to the power display and replace the battery in time
