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.
