Description: Measurement Range:- 50 to 110C Material:Circuit board + Plastic Size:60 * 45 * 31mm / 2.36 * 1.77 * 1.22inch Measurement Accuracy:0.2 Control Accuracy:0.1 Voltage:12V/24V/220V Display Type:Digital Load Power:120/240/1500W Measurement Input:NTC10K waterproof probe L = 1 Output Capacity:Max 10 Package Include:1pc Digital LED Temperature Controller Feature: Heating/refrigeration modes, users can set the start/stop temperature freely;With large and clear LED display for better readability Easy to use:Three buttons for easy operation, to set start temperature, stop temperature, corrected temperature, delay start time. Two Work Mode:Heating ( start temperature is le than stop temperature), Cooling ( start temperature is above than stop temperature) Applycation:Waterproof sensor, can be used to detect water or other liquid non-corrosive. objects temperature, for aquaculture,ornamental fish and other Operation Instructions: Set the start temperature; pre the up button on one time to show the starting temperature, pre the upper key for about 3 seconds, start temperature and digital flicker, and set the required temperature value through the upper and lower keys. Set the stop temperature: pre the next button to show the stop temperature, pre the key for about 3 seconds, stop the temperature, and digitally flicker, and check the required temperature value through the upper and lower keys. Restore factory setting: under the condition of electricity, at the same time hold down the upper and lower keys, the digital tube display 888 then automatically jump to the detection temperature, can restore the factory setting; Start temperature < stop temperature = heating mode Start temperature > stop temperature = refrigeration mode Prompt: When setting up the heating mode, if the temperature value is set upside down, the output indicator will not be lighted and the load will not work. If the above situation occurs after the completion of the setup, we can check whether the temperature value of the set is reversed. Notes: 1.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 2.Please allow 1-3cm measuring deviation due to manual measurement. Package Include: 1 x 12V/24V or 110-220VDigital LED Temperature Controller
