PMT ALPHA Articulated Arm: Precise Measurement, Rich Performance to Meet Diverse Needs:
The ALPHA articulated arm adopts a built-in balanced structure and equal arm length design most suitable for on-site measurement. The structure is simple, balanced, and the operation is flexible and smooth, with bold innovations in detail. The arm body is made of aviation carbon fiber material, effectively ensuring thermal stability.
Each PMT articulated arm undergoes rigorous extreme temperature cycle testing (-20℃~60℃), impact and vibration testing according to IEC standards. Rigorous accuracy verification is performed according to the ISO10360 international standard to ensure accuracy, consistency, and reliability of measurements in various environments.
In addition, the ALPHA articulated arm supports multiple data transmission methods such as USB and Wi-Fi, facilitating data synchronization and management with computers or other devices. Except for the E series, articulated arms are available in both 6-axis and 7-axis versions to meet the needs of different application scenarios.

Product Inspection
1) Portable measurement arms can perform online dimensional measurements for on-site inspection, unlike traditional measurement methods. 。
2) Design Improvement: Using a portable measurement arm for computer-aided inspection of products can promptly identify discrepancies between the product and the original design, allowing for improvement of product design and manufacturing processes.
3) Rapid Design: Implementing design schemes based on existing products or partially using reverse methods.
4) Component Archiving: Archiving components without design prototypes or drawings for future use.On-site Inspection in the Production Workshop
1) On-site Measurement: The measurement arm has no special environmental requirements and can be used in production workshops.
Using a measurement arm for on-site measurement in production can promptly identify product quality issues (deformation, wear, etc.), reducing the defect rate.
2) Measurement of Complex Workpiece Parts: On-site measurement of various jigs, fixtures, platforms, automotive interior parts, pipe fittings, and other large and small products.
3) Online Inspection: Traditional methods cannot be used for online inspection. Measurement arms can be used for online or in-machine inspection during product processing, offering good flexibility and high cost-effectiveness.Management Optimization and Risk Control
1) Product Manufacturing Process Optimization: 100% online inspection of products allows for timely acquisition of data from the product manufacturing process to make informed management decisions.
2) Operational Risk Control: On-site measurement of products allows for the prompt identification of problems such as deformation and wear, enabling timely adjustments to molds and production processes, reducing the risk of subsequent assembly defects or other flaws.Below, we will introduce the P, M, E, and EDU accuracy level products in the ALPHA series, showcasing their unique charm from multiple dimensions, including range, measurement error, axis configuration, and optional accessories.
1.ALPHA-P Articulated Arm: Flagship High-Precision Series

As PMT's flagship product, the PMT ALPHA-P series boasts extremely high measurement accuracy and excellent stability, helping our customers stay ahead in quality control.
The range of ALPHA-P articulated arms covers 1.5m~4.5m, with 7 range specifications in 0.5m intervals. The ALPHA-P 7-axis articulated arm comes in six standard specifications from 2m~4.5m to ensure that the measurement needs of workpieces of various sizes are met.
It is worth mentioning that, in addition to the 7 axes, the ALPHA P series articulated arms can also be optionally equipped with an HD (high configuration) or SD (standard configuration) scanning head, which can perfectly solve the problem of difficulty in accurately reaching the contact probe under irregularly shaped surfaces.
2.ALPHA-M Articulated Arm: All-round High-Precision Series

3.ALPHA-E Articulated Arm: Ultra High Cost-Effectiveness Series

The PMT ALPHA-E is a highly cost-effective articulated arm, mainly featuring a 6-axis contact-type articulated arm (ALPHA E 6 AXES), focusing on reducing costs while maintaining accuracy.
The ALPHA E 6-axis comes in 7 range specifications: 1.5m, 2m, 2.5m, 3m, 3.5m, 4m, and 4.5m. Its measurement accuracy and range are sufficient to handle most daily measurement tasks, making it an ideal choice for businesses seeking cost-effectiveness.
4.ALPHA-EDU Articulated Arm: Designed for Education

The PMT ALPHA-EDU series is an articulated arm developed by PMT specifically for college education, aiming to maximize value for colleges and steadily improve creativity and productivity.
