Features:     1. This product belongs to industrial product of heating air to heat and solder components or board. 2. With 3 memory channels: CH1, CH2 and CH3. After custom setting the temperature, air volume and time of each channel, can be conveniently switched to the temperature required for heating and soldering components by one key. 3. The handle has sensor switch, as long as hold the handle, the system can quickly enter into the working mode. If the handle released into the handle frame, the handle will cool down to below 100& 8451; and enter standby mode, real-time and easy operation. 4. The parameters also can be custom set in the sleep state. 5. Sensors closed loop, zero-crossing triggering microcomputer temperature control, LCD touch screen. Heating up rapidly, the temperature accuracy and stability, without effect of the air flow, and truly achieved lead-free solder. 6. Using variable frequency brushless fan, adjustable air flow, large range, and can adapt to a variety of purposes 7. The system has automatic air cooling function, to extend life and protect the hot air heater.   Specifications:   Model: BST-863 Power: 1200W Input Voltage: AC 220V/110V 50/60Hz Temperature Range: 100& 8451;~550& 8451; (212& 8457;~999& 8457;) Display Type: LCD screen Temperature Accuracy: ±1& 8451; (Static) Air Volume Range: 1~100 Level Noise:
