Overview
The DONGRU DR87 Ultrasonic Thickness Gauge is a Portable thickness gauge that can pass through coatings and can nondestructive test the film thickness of pipes and other materials. The instrument works through an external ultrasonic Probe, is battery powered, and the measurement results are displayed visually on the LCD screen. It has 2000 sets of data storage capacity. Its operation panel comes with a calibrated base, which can be calibrated by sonic speed for Film thickness measurement.
Features
1. Can pass through the coating thickness measurement, without removing the surface of the object to be measured paints, plastic and other attachments can be measured substrate Film thickness.
2. Provide a user-friendly data storage mode, which can be saved in groups and can choose the amount of data saved in each group to simplify operations.
3. With a variety of practical measurement modes, including standard measurement mode, MAX Maximum measurement mode, MIN Minimum measurement mode, difference measurement mode, average measurement mode, high temperature measurement mode (with high temperature Probe).
4. Film thickness measurement.
5. Probe zero auto calibration.
6. Large-capacity data storage, with a data storage capacity of up to 2000 sets.
Principle
DR87 Ultrasonic Thickness Gauge adopts the principle of ultrasonic nondestructive testing, which can measure the thickness of the substrate through the coating, and can measure the film thickness without removing the coating and Non-metallic adhesion on the surface of the tested object.
Applications
Film thickness measurement
Steps
1. Install the battery and connect the Probe.
2. Turn it on, set the sound speed according to the measured material or use the calibrating base that comes with the instrument to calibrate.
3. Vertically and stably couple the Probe to the surface of the tested object.
4. Select the appropriate measurement mode (e.g. standard, maximum, minimum, differential, average or high temperature mode).
5. Read the Film thickness data displayed on the LCD screen.
6. Use the data saving function to store the measurement results in groups as needed.
Notice
• Make sure that the Probe is well coupled to the measured surface during measurement.
• Probe contact temperature range is -10~ 50 ℃, beyond this range need to use special high temperature Probe (up to 300 ℃).
• When measuring pipes, the lower limit is φ 15 * 1.0mm.
• When crossing the coating measurement, the coating thickness range should be between 3mm and 20mm.
• If you need to measure coarse grain materials such as gray cast iron, you need to buy a special coarse crystal Probe.
When not in use for a long time, remove the battery.
