Introduction of Sf2001 High Precision Time Calibrator Portable Stopwatch Calibration Instrument
The Sf2001 High Precision Time Calibrator Portable Stopwatch Calibration Instrument is a precision calibrator instrument for 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.
