Overview
The DB22-CM222 Coating thickness gauge is a battery-powered Portable measuring instrument that uses magnetic Induction and eddy Current principles and complies with ISO2178, ISO2360, GB4956 and GB4957 standards. It uses computer technology and nondestructive detection technology to accurately measure Coating thickness without damaging the subject. It has the characteristics of small measurement error, high Reliability, good Stability and easy operation. It is a reliable nondestructive testing instrument for controlling and ensuring product mass. It is suitable for engineering sites and laboratories.
Features
1. Can store 99 sets of measurement data; 2. With statistical function, automatically calculate MAX Maximum, MIN Minimum and average value; 3. With male and imperial unit conversion; 4. Automatic shutdown and undervoltage prompt function; 5. Can automatically remember the calibrated value, and can automatically identify the material of the tested substrate; 6. Use USB, Bluetooth data output to communicate with PC.
Principle
The DB22-CM222 Coating thickness gauge is based on the principle of magnetic Induction and eddy Current for measurement. The F-type Probe uses the principle of magnetic Induction to measure the thickness of the non-magnetically permeable covering layer on the surface of magnetically permeable materials (such as iron, nickel); the NF-type Probe uses the principle of eddy Current to measure the thickness of the insulating covering layer on the non-magnetically permeable metal substrate (such as aluminum, copper, zinc) to achieve nondestructive detection.
Applications
F Probe: platings, paints layer, enamel layer, aluminum tile, copper tile, Babbitt tile, phosphating layer, Paper thickness measurement, hull paints and underwater structural parts attachment thickness measurement; NF Probe: aluminum, copper, zinc, non-magnetic stainless steel and other materials Surface paints, plastic, rubber coating measurement, anodic oxidation layer thickness measurement of aluminum or aluminum alloy materials
Standards
ISO2178、ISO2360、GB4956、GB4957
Steps
1. Install 4 AA batteries; 2. Select F-type or NF-type Probe according to the base material; 3. Place the Probe on the measured surface for measurement; 4. The instrument automatically recognizes the base material and displays the thickness value; 5. Use the statistical function to view MAX Maximum, MIN Minimum and Average; 6. Output data to PC via USB or Bluetooth.
Notice
- Ensure that the Ambient Temperature is within the range of 0~ 40 ° C and Humidity is within the range of 10~ 90% RH; - Pay attention to the minimum surface requirements during measurement: F-type Probe convex 1.5mm/concave 25mm, NF-type Probe convex 3mm/concave 50mm; - The minimum measurement area is 6mm; - The thinnest substrate is 0.3mm; - Regularly check the battery power to avoid undervoltage affecting the measurement; - Shut down in time after use to save power.
