Applications
The integrated design of the sandblasting roughness meter DB20-SRT231 complies with ASTM D4417 method C and NACERP0287-95 test method. It can directly measure the height of the peak and valley of the surface. It is suitable for: shot blasting industry, printing industry, spraying It is used in industries with surface roughness requirements such as the anti-corrosion industry. The corresponding parameters are calculated based on the selected measurement conditions, and all measurement parameters are clearly displayed on the LCD display.
Features
Comply with the test methods of ASTMD4417-B, IMO MSC 21882, SANS5772, USNavy NSI009-32, US Navy PPI 63101-000.
Metric/imperial unit conversion; with maximum value latch, under-voltage alarm indication function, automatic shutdown and manual shutdown functions.
Use "USB data line output" and "RS-232 data line output" to communicate with PC. Provides "Bluetooth™ data output" selection.
