English Product Introduction
The DT-2239A digital stroboscope is a high-precision instrument featuring microprocessor-controlled quartz oscillation for accurate rotational speed measurement. With 0.3-inch 4-digit LED display, it covers measurement ranges of 100-10000 beats per minute or 100-10000 RPM. The xenon flash tube emits 6500°K white light with 80-degree beam angle, providing clear visualization of moving objects. 313
Key Features
This stroboscope incorporates advanced LSI microcomputer IC technology with crystal-controlled timebase, eliminating the need for external calibration. The dual-range selection (100-1000/1000-10000 RPM) and rotary knob adjustment ensure user-friendly operation. Automatic range switching and sampling time of 1 second enhance measurement efficiency. The compact design (21x12x12cm) with lightweight construction facilitates field applications. 1923
Operational Advantages
Featuring 4W flash energy and 60-1000ms flash duration, the device enables non-contact measurement of rotating machinery including gears, centrifuges and motors. The innovative power-saving design includes auto-shutdown after 1-minute inactivity and low-battery warning. The sturdy ABS housing provides durability in industrial environments while maintaining portability. 715
Application Scenarios
Ideal for troubleshooting in manufacturing processes, the DT-2239A assists in inspecting high-speed printing color registration, textile spindle rotations, and mechanical vibration patterns. By synchronizing flash frequency with object motion, it creates optical freezing effects for detailed analysis of dynamic processes in packaging, metalworking and assembly lines. 2124
