Digital Temperature Probe (SN-100)
Altrac's digital temperature probe (SN-100) plugs directly into the Wind Machine Station (ST-100). The temperature probe is accurate to +/-0.9F and used to power the frost alarm and actuate the wind machine autostart.
The temp probe is 40' long and plugs directly into the ST-100. The automotive grade connector is located at the base of the wind machine on ground level of the orchard. The probe uses 18 AWG wire for easy field repair. All components are UV resistant and wrapped in a rodent resistant nylon sheath to protect against damage in your field.
This probe does not require calibration.
