Description
Product Introduction:
The parameters provided by the handheld surface roughness tester comply with GB/T 3505-2000 “Geometrical Product Specifications—Surface Texture—Profile Method—Terms, Definitions and Parameters,” as well as with GB/T 6062-2002 “Geometrical Product Specifications (GPS)—Surface Texture—Profile Method—Nominal Characteristics of Contact (Stylus) Instruments.” Scope of application: measurement of surface roughness on both metallic and non-metallic workpieces; suitable for a wide range of machined parts, mechanical manufacturing, inspection, and commodity inspection departments. It is particularly well-suited for on-site inspection of large workpieces and production lines, as well as for field calibration by inspection, metrology, and commodity inspection agencies, without causing any damage to the workpiece. Measurable workpiece surfaces include flat surfaces, external cylindrical surfaces, conical surfaces, internal bores, grooves, curved surfaces, and other irregular shapes (with appropriate sensors).
Product Features
After rigorous temperature and humidity testing, the device is well-suited to high-temperature, high-humidity operating conditions; in particular, its measurements remain unaffected even in the humid climate of southern regions. It delivers high accuracy and stable readings.
1. Wide measurement range, multiple parameters: 14 parameters in total—Ra, Rz=Ry (JIS), Rq, Rt=Rmax, Rp, Rv, R3z, R3y, RzJIS, Rs, Rsk, Rk, Rsm, and Rmr.
2. The calibration block is made of an optical glass substrate, certified by the National Institute of Metrology, offering high accuracy, resistance to scratching, and a long service life.
320×240 true-color TFT display, digital/graphic display; high brightness with no viewing-angle dependence;
3. It employs a DSP chip for control and data processing, offering high speed and low power consumption.
4. Mechatronic design, compact size, lightweight, and easy to use;
5. Features a sensor stylus position indicator;
6. Compatible with multiple national standards, including ISO, DIN, ANSI, and JIS, from the United States, Germany, Japan, and the United Kingdom;
7. The display provides rich, intuitive information and can show all parameters and graphical representations.
8. Built-in lithium-ion rechargeable battery and charging control circuit, with high capacity and no memory effect;
9. Features a remaining battery level indicator to remind users to recharge promptly.
10. It can display the charging process, allowing the operator to monitor the charge level at any time.
11. Continuous working time exceeds 20 hours
12. Large-capacity data storage, capable of storing 100 sets of raw data and waveforms.
13. Can connect to a dedicated Bluetooth printer to print measurement results on-site.
14. Real-time clock setting and display, facilitating data recording and storage.
15. Features power-saving functions such as automatic sleep and automatic shutdown.
16. Reliable circuit and software design to prevent motor stalling, ensuring high stability;
17. Displays measurement information, menu prompts, error messages, and various status indications such as power‑on/off;
18. Chinese/English language selection;
19. Optional accessories include curved‑surface sensors, small‑hole sensors, groove sensors, measurement platforms, sensor protective sleeves, extension rods, and more.
