Smart (manual) ※ simple thermostat mounted on a wall or take 863 boxes; ※ temperature at 0 ℃ -30 ℃, can be adjusted as desired; Features ※ with power, working status indicator; ※ with the ambient temperature changes Automatic switching electric heating equipment; ※ has geothermal dual control function; ※ anti-moisture, anti-smoke, anti-fungal. ※ Specifications Rated operational current: 16A / 30A / 40A / 50A ※ Since the consumption power: <2W ※ Operating voltage: 220 ± 5% VAC tube resistance furnace prices, 50Hz ※ Sensor Type: LM35DZ ※ sensor temperature control range: 5 ℃ ~ 30 ℃ ※ temperature control accuracy: about 1 ℃ ※ Working temperature: 0 ℃ ~ 45 ℃ ※ humidity range: 5% to 9% (non-condensing) Installation and Use 1. No special installation tube furnace resistance furnace operation, Just flat on the floor or bench indoors. The controller should be on the table, tilt work surface shall not exceed 5 degrees. The controller furnace minimum distance of not less than 0.5 meters away. The controller should not be placed above the furnace, so as not to affect the controller is working. 2. Control is connected to power lines and electric resistance furnace tube, switch and fuse load capacity should be slightly larger than the electric power rating. 3. wiring, first turn the screw loose controller left and right sides of the shell, and then turn on the cover tube resistance furnace manufacturers, according to the illustrated connect the power cord. The controller and electric wires and thermocouple cable (best to use compensation wire). The thermocouple thermocouple inserted into the furnace from the hole in the holder, the gap between the hole and the thermoelectric clogged with asbestos rope, then fixed (Note: The power phase - and neutral is not reversed, in order to operate safe, reliable ground controllers and electric required) SK2 series of tube-type laboratory furnace | Longkou laboratory furnace.
