Phytos 31 by Meter Group
"NOTE: The PHYTOS 31 is intended only for use with data loggers and readout devices that can provide short excitation pulses, leaving the sensor turned off most of the time. Continuous excitation not only wastes battery power, but may, under certain circumstances, cause the sensor to exceed government-specified limits on electromagnetic emissions"-Meter Group
