Digital Stop Watch

A handy digital stopwatch for timing applications

Time is an essential parameter in a number of air pollution monitoring applications. Accuracy of timing and time measurement is of paramount importance in air pollution samplers where the measurements are dependent on sampled volume which in turn is computed from flow rate and duration of sampling.
