The surface roughness meter GR110
The temperature and humidity of surface roughness meter GR110 pass strict test to adapt to the high temperature and high humidity working environment.Using high-speed DSP structure design and optimization of the sensor, the electric box, drive and display part, to the highly integrated;Choose any Ra, Rz, Rt, Rq four measuring parameters;Not only can measure plane, more than 20 mm diameter (by experience) of the cylindrical surface, conical surface, can also be measured width greater than 80 x 30 mm groove.
Dedicated to a new type of intelligent test of metal and nonmetal work-piece surface roughness nondestructive testing instrument, applicable to a variety of machining parts, mechanical processing, manufacturing, inspection, commodity inspection departments, especially applicable to large work-piece and the field inspection of the production line, and the detection, measurement, commodity inspection departments of out verification, will not have damage on the work-piece.
Main functions:
Can choose 4 kinds of measuring parameters of Ra, Rz, Rt, Rq;
Calibration sample piece is optical glass substrate by the identification of a national metrology institute, high precision, not easy scratches, long service life;
Have calibration function, the operation is simple;
Widely used in metal and non-metallic processing on the surface of the production site and out appraisal test;
High-speed DSP processor is adopted to improve the data processing and computation, faster speed, higher accuracy;
Can choose sampling length of 0.25, 0.80, 2.50;
LED dot matrix LCD, high brightness, no visual Angle, wide temperature, suitable for various occasions;
Automatic shutdown function, software & hardware design of low power consumption make instrument long working time;
Two charging ways, special charger or computer USB port, can charge while working, convenient and quick;
Sensor head protective door, effectively protect the sensor head, ensure the accuracy of the measurement;
”U” shape using the aluminum mold design, durable, resistance to electromagnetic interference ability significantly, conform to the new trend in today's design.
