Good quality: Embedded CPU chip (MCU), more intelligent, lower power consumption. 100% complete machine patch, wave soldering, stable performance, good consistency. LED digital thermostat: the LED digital thermostat W1209 has a sensor input, buttons, an LED display and a relay. It can be used to control temperature. Waterproof sensor probe: LED digital thermostat as the measurement input, a waterproof NTC (10K 0.5%) sensor probe is used. The NTC probe is waterproof and allows you to control the temperature even of liquids, allowing controlled heating or cooling. Easy to use: the control of the thermostat module has a sensor input, buttons, LED display and a relay. It can be reprogrammed for control, timing or counting. Temperature Measurement Range: -50~110℃ Control Precision: 0.1 celsius Input Power (DC): 12V Measuring Inputs: NTC (10K 0.5%) Waterproof Sensor: 0.5M Output: 1 Channel Relay Output Capacity: 10A Power Consumption: Static Current: 35mA Current: 65mA Material: Metal colour: As Shown Package Contents: 6 x temperature control panel Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
