SR9223 Surface Profile/form Tester

* This Digital Surface Profile Gauge is a handheld gauge for fast and accurate measurement of the peak-to-valley height of the surface profile of blast cleaned surfaces.

* It meets the standards of ASTM D 4417-B, IMO MSC.215(82), SANS 5772, US Navy NSI 009-32, US Navy PPI 63101-000. Suitable for the laboratory and for use in harsh field conditions. Accurate, immediate and repeatable results.

* The tungsten carbide tip will last for up to 20,000 readings and can then be easily replaced by the user in the field.

* Cost per test is significantly lower than other test methods.

* Used the exclusive Micro -computer LSI circuit and crystal time base to offer high accuracy measurement.

* Can communicate with PC for recording, printing and analyzing by the optional software and cable for RS232 interface. USB adaptor and Bluetooth interface can also be used.

* Automatic power off to conserve power.

* Widely used in field of blast cleaned surface measurement. If the profile is too large the amount of coating required to ensure adequate coverage increases, otherwise there is a danger that the peaks remain uncoated - allowing rust spots to occur. If the profile is too small, there maybe an insufficient key to produce adequate adhesion, leading to premature coating failure . Ensuring the correct surface preparation optimises the performance of the coating and material usage.
