OPERATION AND MEASUREMENT
Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying
or recording a millivolt signal (an input measurement range of approximately 0-25 mV is required to cover the
sensor output ranges). In order to maximize measurement resolution and signal-to-noise ratio, the input range of
the measurement device should closely match the output range of the sensor. DO NOT connect the sensor to a
power source. The sensor is self-powered and applying voltage will damage the sensor.
