The Hioki 3639-20 FMI Pulse Logger is a single channel data logger for rain guage or illumination measurement and serves as a pulse totalizer for hygrometers, flowmeters, and powermeters. With its ability to accumulate up to 9,999 counts and noise filtering to minimize miscounts, this field measuring instrument ensures accuracy where it is most needed. An alarm outlet with selectable threshold is provided. The unit can be combined with Hioki software (Hioki 3912-20) for the processing and storage of over 32,000 measurement data including recording time, interval, start, end, method, and comments in the instrument's memory. Even in the case of battery depletion, the unit contains a non-volatile memory that preserves collected data. For added convenience, the unit comes with batteries, a connection cable for measurement input, and connection cable for alarm output.
