PS-50H Single-row Display Stopwatch Introduction: The PS-50 single-row display stopwatch is an electronic timing device centered around a high-precision quartz crystal oscillator. It is specifically designed for time interval measurement needs in various scenarios such as sports events, laboratory analysis, and industrial inspection. This product utilizes a single-row high-brightness digital display scheme, coupled with a simple operation logic and stable core performance, to achieve clear presentation and precise capture of time data. Its technical specifications strictly comply with JJF 2195—2025 "Stopwatch Calibration Specification" and relevant industry standards, providing users with a reliable timing solution.
