Overview
The DONGRU DR230 Coating thickness gauge is an eddy Current/magnetic Induction dual-use Coating thickness gauge with an integrated structure with a built-in probe, which can automatically identify ferrous or non-ferrous substrates. The instrument has Data storage function, supports zero and two point calibration methods, and has automatic shutdown function. It is small in size but powerful in function. The DR230 Coating thickness gauge is widely used in manufacturing, metal processing, chemical industry, commodity inspection and other fields. The integrated design makes it easy to carry and accurate in measurement.
Features
1. Small integrated design, easy to carry
2. Simple operation, Test speed
3. Can store 116 measurement data
4. Can be connected to a computer for communication and read out stored data
5. Calibration methods: zero point calibrating and two point calibrating
6. There is a beep during the operation (Single Measurement mode)
7. Automatic identification of ferrous and non-ferrous substrates
8. Low voltage indication function
9. Manual/automatic shutdown function
10. Test methods: Continuous Test and Single Measurement mode
11. Four statistical functions: MAX Maximum, MIN Minimum, Average, Number of measurements
Principle
The DR230 Coating thickness gauge uses magnetic Induction and eddy Current Measurement principles. The magnetic Induction method provides nondestructive measurement of the thickness of nonmagnetic coatings on magnetic metal substrates (e.g. steel, iron, nickel); the eddy Current method provides nondestructive measurement of the thickness of nonconductive coatings on nonmagnetic metal substrates (e.g. aluminum, copper, stainless steel). The instrument can automatically identify the substrate for fast, non-destructive measurement of the thickness of metal surface coating platings.
Applications
Manufacturing, metal processing, chemical industry, commodity inspection
Steps
1. Zero calibrate: Place the Probe vertically on the base, press the live zero button "ZERO", and then release it. You can't lift the Probe until "CAL" is displayed on the display.
2. Two-point calibrating: first calibrate the zero position; then select a close diaphragm according to the measurement requirements and place it on the calibrated substrate for Probe measurement; if the measured value is different from the diaphragm, lift the Probe and use the "+" "-" button to correct.
Notice
• When the zero position is calibrated, the Probe must be lifted after the display shows "CAL", otherwise the calibrate fails.
• When calibrating at two points, you need to calibrate at zero first
• When using diaphragm calibrating, choose a diaphragm close to the measurement requirements
• Measured values do not match, can be corrected by the "+" "-" button
