Usage Tips:1. High precision: The high-precision probe of the controller ensures measurement accuracy with small error values, making it very suitable for places that require constant temperature. 2. Stable performance: The controller adopts a wide voltage power supply, which can work normally even if the voltage is unstable. 3. ABS shell: The ABS material of the socket shell has strong insulation, which can the of the socket without leakage. 4. Easy to use: The thermostat can be used after being inserted into the circuit, supporting Celsius readings, making it convenient and practical. 5. Wide application: the controller can be used in fish tanks, aquariums, seedlings, greenhouses, floor heating, electric beds, Electric blanket, electric fans, fermentation, planting, preservation, experimental ovens, etc. Temperature measurement range:9-99 Control accuracy:1 Measurement accuracy:0.1 Resolution:0.1 Power supply:AC 110V-240V Refresh rate:0.5s Temperature calibration range:(+/-) 9 Measurement input: (10k0.5%) waterproof sensor Output:One side load of relay 10a Static current:less than 40ma Pickup current:less than 65ma Working environment:10-60, humidity 20%-85%.
