Features Temperature Calibration Function: Digital STC -000 temperature controller is a supporting temperature calibration function, and can also be protected in refrigerated control output delay. Alarm: The all-purpose temperature controller can send an alarm to remind a warning when the temperature exceeds the temperature limit or the sensor error, which is very convenient. Control temperature: The temperature controller can control the temperature by setting the temperature setting value and difference, with high accuracy, high sensitivity, high stability and durability. Mode Switching: Digital constant temperature controller can switch between the device control heating mode and refrigeration mode of inserting the controller. Application: Multi -purpose temperature controller can be applied to aquarium, glass container, zoo, Paludarium, chicken incubator, etc., and the scope of application is wide. Features: 1.Switch the modes between cool and heat. 2.Control temperature by setting the temperature set value and the difference value. 3.It supports temperature calibration function. 4.Refrigerating control output delay protection. 5.Alarm when temperature exceeds temperature limit or when sensor error. 6.Application: aquarium, terrariums, zoo, paludarium, chicken incubator.
