OPERATION AND MEASUREMENT
Connect the detector to a measurement device (meter, datalogger, controller) capable of inputting 2.5 V DC, and
measuring and displaying or recording a millivolt (mV) signal (an input measurement range of 0 to 2500 mV is
required to cover the entire temperature range of the detector). 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
thermistor.
VERY IMPORTANT:
In January 2022, the SF-110 (formerly called the leaf and bud temperature sensor) underwent a
redesign to improve performance and ruggedness. As part of this redesign, the bud temperature sensor was removed, as it
was determined the leaf measurement was most critical. The SF-110 was renamed the radiation frost detector.
