Product Description
The ODM/OEM Surface Roughness Tester include two models, BR-3932/BR-3932B. It is 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.
Product Feature
* Be compatible with four standards of ISO, DIN, ANSI and JIS. 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.
* Multiple parameter measurement: Ra, Rz, Rq, Rt.
* Highly sophisticated inductance sensor.
* Four wave filtering methods : RC, PC-RC, GAUSS and D-P.
* Built-in lithium ion rechargeable battery and control circuit with high capacity.
* Small in size, light in weight and easy to use.
*Manual or automatic shut down.
* Can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.
* Metric /Imperial Conversion.
* Use USB data output with connection PC.
* Provide Bluetooth data output choice.

Buying Guide
When you choose the model number of Amittari instrument, the default is standard delivery. If you need other optional accessories, please tell our customer -service worker.
The following three items are basic optional accessories choices
Standard Accessories+USB data output
Standard Accessories+Bluetooth data output
Bluetooth Accessories
Amittari instruments generally can be supplied with Bluetooth data output function ( except few instruments ) . As Bluetooth data output is included in optional accessories, not standard delivery, it needs to be indicated when choose 10 meters to 100 meters distance can be chosen. Please kindly contact with the customer-service worker if you need Bluetooth data output.
