Programmable Thermostat Features ※ microcomputer automatic imitation Chi logic design, programmable timer / temperature selector; ※ several ushers style, large LCD screen, touch button allows you easy to operate, you can set the date and time display ; ※ Built-in six to nine programs, users can own programming, the user can select the temperature at different times of the week according to their preferences; ※ overheat protection: When the heating device temperature exceeds a preset temperature thermal protection, temperature control automatically cut off the power supply heating equipment; ※ anti-frost function, maintaining the temperature at 5 ℃ unchanged; ※ have geothermal dual control functions. Check wiring and correct to electricity, the first on the power switch, and then the toggle switch on the control panel to pull the open position, adjust the settings button, set the temperature to the degree that you need, if the set given to the measuring position pull switch on the red light off (NO), also pull contactor sound, electric powered laboratory furnace, heating ammeter indicates the current value, the furnace temperature with increasing temperature slowly rising, indicating that work. When the temperature rises to set the desired temperature, the red light is off (NO) tube-type laboratory furnace, the green light (YES), automatic electric power, stop heating up. Later, when the furnace temperature dropped slightly high temperature laboratory furnace, green light is off, the red light, electric powered and automatically cycle to achieve automatic control of temperature in the furnace in order to check whether the purpose of .5 burnout protection devices work properly universal laboratory furnace, the method is: Loosen the thermocouple end, this When the temperature quickly rose to the highest point instructions also automatically cut off the heating power, the good burnout device, reconnect after a good thermocouple, can work. _ high temperature laboratory furnace factory direct (certified) _ laboratory furnace laboratory furnace by Longkou plant available. Longkou experiment Furnace (www.lk-dianlu.com) is a leader in Yantai, Shandong Province, electric equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
