Introduction
The calibrator is a precision instrument calibrating mechanical stopwatch, electronic stopwatch, and 405/407/408/415/417 type pointer electric stopwatch. The SF2001 stopwatch calibrator is compliant with the stopwatch calibration procedure JJG 237-2010 issued by the National Metrological Bureau. It could be used at metrological department at all levels, factory, institutions and all research institutes to calibrate electric stopwatch (405,407,408,415/417), mechanical stopwatch and digital quartz electronic stopwatch. The instrument is fully digitally controlled, high reliability,high accuracy, complete functions, convenient operation, and strong anti-interfere
ability.
