We present pigtailed electro-optic probes that allow a simultaneous measurement of high frequency electric fields and temperature using a unique laser probe beam. This has been achieved by the development of a novel probe design associated with a fully automated servo-controlled optical bench, initially developed to stabilize the electric field sensor response. The developed electro-optic probes present a stable response in outdoors conditions over time duration exceeding 1 hour, a frequency bandwidth from kHz to tens of GHz with a sensitivity of 0.7 V.m-1.Hz-1/2 and a temperature accuracy of 40 mK.
