TR110 portable surface roughness tester is dedicated to measuring the parts to be machined surface roughness of a novel intelligent detection instrument. The apparatus sets the microprocessor technology and sensor technology in one, with advanced microprocessor and preferably highly integrated circuit design, which adapt to the development trend of ultra small instrument system structure, complete the roughness parameter acquisition, processing and display of the work. TR110 surface roughness tester is suitable for a variety of processing machine parts, machinery manufacturing, testing, inspection and other departments, especially for large working piece and production lines of on-site inspection, and testing, measurement, commodity inspection departments outside verification.

 

● Adapted to high temperature and high humidity environment after strict temperature, humidity test.

● Optimized circuit design and design of sensor, the electric box, driver and a display part are combined into a whole,

● Achieve high integration arbitrary choice of Ra, Rz, Rt, Rq four measuring parameters; not only can measure plane, diameter of more than 20mm ( experience) of the cylindrical surface, conical surface, but also be measurement of length greater than 80 x 30mm groove.

 

 Functions:

● 4 selectable Parameters Ra, Rz, Rt, Rq;

● 3 selectable cut off lengths : 0.25., 0.80, 2.50

● Widely used in metal and non-metallic surface production site and on identification of detection

● Using high-speed DSP processor for data processing and calculation, fast speed, high precision

● LED dot matrix liquid crystal display, high brightness, without perspective, wide temperature, suitable for all occasions

● Calibration function with simple operation

● Automatic shutdown function and low power consumption design of hardware and software make the instrument working time long;

● Two charging methods, special charger or a computer USB port charge, while charging while working, convenient and quick

● Sensor head having a door protection, effective protection of the sensor, which can ensure the measurement precision;

● Shape using pull aluminum mold design, durable, anti-electromagnetic interference ability significantly, with the current design trends.

 

 Technical Specification:

 

● Surface roughness: refers to the processing surface with small spacing and the peaks and valleys in the composition of the microscopic geometry features.

● Sampling length lambda C: used to distinguish with the surface roughness characteristics of a baseline length.

● Evaluation length: evaluation of contour to a length, which may include one or several sampling length.

● Arithmetical mean deviation of the profile of Ra: in sampling length within the contour offset arithmetic average

● Root-mean-square deviation of the profile of Rq: in a sampling length within the ordinate value RMS value

● Maximum height of the profile of Rz ( ISO ): in a sampling length, maximum peak high Rp and maximum contour valley deep Rv and height;

● Peak valley total height Rt: in the evaluation of length within the maximum peak high and deep valley and the maximum contour.

● TR110 surface roughness instrument given parameters conform to  GB / T 3505-2000" geometrical product specification - surface texture: profile method, the surface structure of the predicate, definitions and parameters", with GB / T6062-2002" geometrical product specifications ( GPS ) surface structure, contour method for contact ( stylus) instrument nominal characteristics".
