About DLTEREN DTI-SRT-6223 Digital Surface Roughness

The Surface Roughness Tester is from Teren Instruments.Applications: Widely used in production site to measure surface roughness of various machinery-processed parts, calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters. Features: Be compatible with the principles of ASTM D 4417-B,IMO MSC.215(82), SANS 5772, US Navy NSI 009-32, US Navy PPI 63101-000. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD. With average calculation function. Provide Bluetooth data output choice. Display: 4 digits, LCD Range: 0~800 um +-5% or +-5 µm,(whichever is the greater) Resolution: 0.1 μm (When Measurement Value less than 100 μm) 1 μm (When Measurement Value great than or equal to 100 μm) Operating Conditions: temperature: 0 ~ 50 degree Humidity：less than 80 %RH Battery Supply: 4 x 1.5v AAA size (UM-4) battery Dimensions: 162 × 65 × 28 mm Weight: 280 g Package includes: 1.
