IR02-TR is a IR02 pyrgeometer with adapted housing, to accept a transmitter or amplifier that can be programmed at user's convenience. The signal from the thermopile is converted from milliVolt signal to the output of the transmitter. The signal from the internal Pt100 temperature sensor is not affected by the transmitter, nor is the control of the heater. Programming can be done either by Hukseflux, or the user, provided the right software is used. User can choose to have his own transmitter placed in the housing, provided it is of DIN form B.
