Surface Profile Gauge

Caltech Engineering Services offers a Surface Profile Gauge that allows the peak-to-valley height of blast-cleaned surfaces to be accurately measured in accordance with the ASTM D-4417 Method B standard. The surface profile gauge is important tool in assessment of degree surface preparation or surface cleanliness before painting application. These gauges are supplied in analog and digital versions: Analog Surface Profile Gauge, R1005 (range 0-1000 µm) 2 µm, and Digital Surface Profile Gauge, R1020 (range 0-1000 µm) 1 µm. The surface profile gauge is initially set to zero with the glass zero plate. To measure profile, the needle of gauge is placed on blasted surface and base of gauge is then placed on the blasted profile. The foot sits on top of the peaks and the needle moves up or down to the bottom of the valley, allowing the surface profile gauge to display the peak to valley height. A number of measurements can be made and the average taken for accurate results of blasted profile. In addition the surface profile gauge can also be used to measure the effects of corrosion, i.e. pitting and cavity depth, etc. The surface profile gauge can be used as per ASTM 4417 specifications. Caltech surface profile gauge is supplied in carrying case with glass zero plat, Allen key, and operating manual in a case. Caltech Engineering Services is a leading company in India to provide one stop solutions for instruments, equipment and supplies useful in the field of paint and coating, corrosion testing, cathodic protection, non destructive testing (NDT), and welding inspection instruments. This wide range of products is manufactured to meet or exceed NACE, ASTM, SSPC, ISO, SIS, IS, BS, DIN and industry standards.
