The explosion-proof vacuum shell of the ring is made of cold-rolled steel plate. The inner liner is made of 304 stainless steel. The surrounding steel is reinforced with steel to ensure its pressure resistance. The door is square double-layer bulletproof glass observation window, and the door seal is made of high temperature resistant rubber strip. Easy to disassemble and replace, and the sealing is excellent. The interlayer is thickened with ultra-fine glass wool, and the temperature resistance is good. The heating pipes are placed on the two sides and the bottom of the box, and the heating is even. The control panel is placed on the side of the box, equipped with a temperature controller, a vacuum gauge and an intrinsically safe type. switch. The solenoid valve is resistant to high temperature corrosion, and the pressure line valves and accessories are made of stainless steel. The vacuum gauge adopts electric contact stainless steel pressure gauge, and its upper and lower limit control contacts are controlled by intrinsically safe solid state relays, which will never generate sparks, and the pressure control is sensitive and accurate. Turn on the power switch when the power is turned on, set the temperature and pressure, the vacuum oven can be automatically constant for a long time at the user's required temperature and pressure point, long-term stable operation unattended. The temperature controller adopts microcomputer intelligent temperature controller with digital display of temperature measurement, clear and eye-catching, and also has delay power suppression and PID self-tuning and over-temperature alarm to automatically cut off the power supply function, high temperature control precision, stable and reliable operation. In addition, the vacuum oven is operated by first evacuating the vacuum when the pressure reaches the set vacuum degree, and the method further prevents the air in the heating box from expanding. The vacuum can also be filled into the box after the vacuum is exhausted, and the blasting box door is prevented. Hot air enters the pressure gauge to protect the solenoid valve and vacuum pump, ensuring safety and reducing malfunctions. This medical nursing model is a great value way to train nurses or students in the correct technique for human body care. Made of PVC Material, Ensure Longer Service Time.Is a rare tool for Medical Training Teaching ang relevant practical training.
