WANDERERBOX ULTIMATE TEMPERATURE PROBE

The Wanderer Astro Temperature Probe for the Wandererbox Ultimate control unit allows you to remotely monitor the temperature of dew heaters for automatic control of their power. 

Note: Wanderer Astro also sells an environment sensor for monitoring of the ambient humidity which also provides automatic control of dew heater power. Only one of these can be used at a time as they use the same single port on the Wandererbox Ultimate, so you do not need to purchase both.
