Remote Sensor Thermostat automatically adjusts terrarium temperatures. Simple to use. You adjust the ReptiTemp Control Knob up or down until the desired temperature level is reached. The indicator light on the thermostat will then cycle of and on to show that the ReptiTemp 500R is working perfectly. When the temperature is under your specified range, heating devices are activated. When optimum temperature is reached, heat is turned off.
Excellent for larger size glass terrariums (40 gallons and up), wood terrariums, acrylic terrariums, or wire cage enclosures.
Not for use with rock heating devices
