SZG-411A非接触手持式数字转速表/SZG411A
产品概述（中英文）
SZG-411A非接触手持式数字转速表是一款采用光电反射原理设计的高精度便携式测量工具，适用于电机及各类机械设备的转速检测。其袖珍型设计便于携带，通过非接触方式（红色LED可见光源）实现测量，有效避免机械接触带来的干扰。该产品具备上限报警、最大值/最小值显示等实用功能，可满足工业场景中的多样化需求。测量范围覆盖10～50000r/min，采样时间仅需1秒，数据通过5秒液晶屏清晰显示，精度根据转速区间分为±1r/min（10～11999r/min）和±2r/min（12000～29999r/min）。工作温度适应0～40℃环境，内置三节五号电池供电，续航稳定。
The SZG-411A non-contact handheld digital tachometer is a high-precision portable device based on photoelectric reflection principles, designed for measuring rotational speed of motors and mechanical equipment. Its compact size ensures easy operation, while the non-contact method (using red LED light source) eliminates mechanical interference. Features like upper-limit alarm and max/min value display enhance practicality for industrial applications. With a measuring range of 10～50000r/min and 1-second sampling time, results are displayed on a 5-second LCD screen. Accuracy varies by range: ±1r/min (10～11999r/min) and ±2r/min (12000～29999r/min). It operates reliably in 0～40℃ environments powered by three AA batteries. 1216

Equipped with a dedicated microcomputer IC chip, the tachometer guarantees rapid sampling and data stability. The reflective measurement distance is 50～150mm, with an "OVER" indicator for out-of-range values. The ABS plastic casing balances lightweight design and durability. Users can align the device with rotating objects via reflective markers for one-touch operation. Additional functions include linear speed calculation (1～5000m/min) and frequency measurement, catering to diverse industrial needs. 6815
应用场景与优势（中英文）
SZG-411A广泛应用于电力、石化、冶金等领域，尤其适合不便直接接触的旋转设备监测。其高分辨率LCD背光屏在弱光环境下仍可清晰读数，且具备数据存储功能（最后一次测量值及过程极值）。相比传统接触式仪表，该产品减少磨损风险，提升测量效率。
Ideal for industries like power, petrochemicals, and metallurgy, the SZG-411A excels in monitoring rotating equipment where direct contact is impractical. The high-resolution LCD with backlight ensures readability in low-light conditions, while data storage (last value and extremums) enhances traceability. Compared to contact-based models, it minimizes wear risks and improves operational efficiency. 101722
