1. 2 Working modes: this digital LED temperature controller module has 2 working modes, heating mode ( temperature is lower than stop temperature) and cooling mode ( temperature is higher than stop temperature), range from -50 to 110; The high temperature control accuracy reaches 0.12. Stable and : the LED indicator light can display the current output status; The digital display tube can display the measured temperature, and the temperature measurement and control accuracy is high3. Durable material: this XH-W3001 digital thermostat switch is made of ABS, one of the major synthetic resins, which is strong impact resistance, heat and low temperature resistance4. Waterproof probe: equipped with a 1-meter NTC10K probe made of stainless steel, which is waterproof and not easy to rust, easy to use and can last for a long time5. Suitable for: the temperature controller module can be widely applied in the conditioning , incubators, equipment cases, temperature control protection and othersSpecification:Name: Microcomputer Temperature ControllerModel: XH-W3001Input Power: DC 12VOutput Power: 120WOutput Type: Direct output (input/output synchronization)Output Current: 10A (MAX)Installation Pitch: 73mm ( 4mm)colour: grayMaterial: ABSsize: 45x60x30mmPackage Contents:3 x Temperature ControllersOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
