A battery-operated circuit for a self-timing leaf diffusion resistance meter.
B. Lammers, Cornelis Johan Stigter · Netherlands Journal of Agricultural Science · 1979
A battery-operated circuit is described for use in self-timing leaf diffusion resistance (porometer) equipment. The circuit is based on an earlier successful design with mains power supply, but some modifications have improved the suitability for routine field use of the equipment.
