DR 432A portable surface roughness tester

1.FEATURES

u This Digital Surface ProfileGauge is a handheld gauge forfast and accuratemeasurementof the peak-to-valley height ofthe surface profile of blastcleaned surfaces.

u It meets the standards of ASTMD 4417-B, IMO MSC.215(82),SANS 5772, US Navy NSI 009-32, US Navy PPI 63101-000.Suitable for the laboratory andfor use in harsh fieldconditions.Accurate , immediateandrepeatable results.

u The tungsten carbide tip will lastfor up to 20,000 readings andcan then be easily replaced bythe user in the field.

u Cost per test is significantlylower than other test methods.

u Used the exclusive Micro -computer LSI circuit and crystaltime base to offer high accuracyMeasurement.

u Can communicate with PC forrecording , printing andanalyzing by the optionalsoftware and cable for RS232Cinterface. USB adaptor andBluetooth interface can also beUsed.

u Automatic power off toconserve power.

u Widely used in field of blastcleaned surface measurement.If the profile is too large theamount of coating required toensureadequate coverageincreases, otherwise there is adanger that the peaks remainuncoated-allowing rust spotsto occur. If the profile is toosmall, there may be aninsufficient key to produceadequate adhesion, leading topremature coating failure .Ensuring the correct surfacepreparation optimises theperformance of the coating andmaterial usage.
