S43131 Series Universal Counter

S43131 series universal counter is the high-precision frequency and time measuring instrument developed by Saluki Technology. It adopts the high-performance single chip microcomputer as the core to conduct function control, survey time sequence control, data processing and result display. Adopt the countdown counting technique and digital interpolation technique to realize high-precision measurement within the whole range.

S43131 series universal counter has stable performance, complete function, wide measurement range, high sensitivity, large dynamic range, high precision, small volume and convenient and reliable use. It has wide application in industrial production, scientific research and measurement and other fields, and is the ideal upgraded and renewed product of the traditional electronic counter.
