The QP-10A Single Axis Laser Diameter Gauge, a practical 0.1–10mm transparent tube single-axis laser scanner, is Qipang’s compact single-optical-path inspection device tailor-made for thin-walled transparent and translucent cylindrical workpieces, covering a measuring range of 0.1mm~10mm with a scanning speed of 1000 times per second.
It features totally different positioning from all 15XY/50XY/70XY dual-axis diameter gauges. Dual-axis equipment adopts 90° dual optical paths to capture bidirectional outer diameter and calculate ovality, while this reliable 0.1–10mm transparent tube single-axis laser scanner only performs unidirectional outer diameter measurement with a smaller footprint and lower purchase cost. As a budget-friendly cost-effective inline wire diameter monitor, it perfectly matches small extrusion, wire drawing and take-up production lines to continuously check the outer dimension of transparent medical catheters, plastic fine filaments, thin bare copper wires and optical coating rods. Users can install this compact laser OD measuring instrument on production lines for 24/7 online monitoring, or fit it with supporting brackets to build an offline testing station. As a professional translucent rod non-contact diameter tester, it solves the long-standing unstable reading trouble when measuring clear plastic and silicone micro tubes.

Core Features
1. Exclusive optical solution for transparent / translucent rods and tubes, unique advantage across the whole series
Most general laser diameter gauges produce obvious data drift caused by light penetration when measuring transparent plastic, glass and thin silicone workpieces. The 0.1–10mm transparent tube single-axis laser scanner adopts customized laser receiving algorithms to filter stray light interference, realizing steady diameter detection for translucent medical catheters, transparent plastic filaments and thin glass rods. This special optical processing function cannot be found on all dual-axis XY series models.
2. Compact single-axis structure for OD-only testing with higher cost performance
Unlike the 15XY/50XY/70XY dual-axis series equipped with dual optical paths and ovality calculation functions, this cost-effective inline wire diameter monitor only uses one laser beam to collect single-direction outer diameter data. Factories that only require outer diameter supervision without roundness inspection can greatly cut equipment investment. Its tiny body can be easily mounted on narrow racks of micro extruders and wire drawing machines.
3. 1000Hz high-speed scanning for fast-running thin wires and tubes
Equipped with high-speed laser scanning hardware and digital signal processing chips, the translucent rod non-contact diameter tester completes 1000 scanning cycles per second. It tracks dimension fluctuations of high-speed extruded thin materials without data delay, and accurately captures tiny tolerance changes during mass production of 0.1–10mm miniature workpieces.
4. Dual-row digital display for intuitive reading, stable operation under wide temperature range
The built-in dual-row 5-digit display shows real-time outer diameter and deviation values at a glance for simple daily operation. As a durable compact laser OD measuring instrument, the whole unit runs stably under -10℃~45℃ and humidity below 85% without condensation, supporting 24-hour continuous operation in small extrusion workshops and indoor laboratories.
5. Standard Modbus RTU communication for quick integration into all types of production lines
Native RS485 Modbus RTU interface transmits real-time outer diameter data to external PLC and control hosts. Users can set dimension interlocks to automatically adjust extruder haul-off speed, building a simple inline closed-loop diameter control system without extra expansion modules. The total power consumption is lower than 15W to save energy during long-hour mass production.

Q1: Can QP-10A measure fully transparent plastic hoses?
A1: Yes. The 0.1–10mm transparent tube single-axis laser scanner is built with dedicated light filtering algorithms to offset light penetration interference of transparent plastic and glass, delivering stable measuring data that ordinary laser gauges cannot achieve.
Q2: Can QP-10A connect to extruder PLC for automatic speed regulation?
A2: Yes. Standard RS485 Modbus RTU communication is supported. Real-time outer diameter and deviation data can be transmitted to PLC to realize simple automatic haul-off speed adjustment, making it a high-value cost-effective inline wire diameter monitor.
Q3: What is the operating temperature range of QP-10A?
A3: The translucent rod non-contact diameter tester runs stably from -10℃ to 45℃ with relative humidity ≤85% non-condensing, suitable for small extrusion workshops and indoor laboratories.
Q4: Can QP-10A be placed on a desktop for offline inspection?
A4: Yes. It can be independently placed on laboratory workbenches for batch sampling inspection of finished transparent thin tubes and fine wires, serving as a portable compact laser OD measuring instrument.
