The SAG-55 Intelligent Hot Air Gun is a newly launched portable smart hot air gun designed to meet various application needs. It uses a microcontroller with PID precise temperature control technology, ensuring rapid heating with minimal thermal shock, which extends the lifespan of the heating element. The brushless fan supports adjustable wind speeds from levels 1 to 20, providing low noise, long life, and adaptability to different work environments. The handle integrates a magnetic sensor that automatically heats up when picked up and cools down into standby mode when returned, making operation simple. The controller and display screen on the handle allow for effortless one-handed adjustment of temperature and wind speed. It also supports three sets of quick temperature/wind speed presets for fast switching.The fast cooling function accelerates cooling, further extending the heating element's lifespan. Real-time monitoring by various sensors ensures the device shuts off heating in case of any abnormalities, ensuring safety. The LCD display and LED indicator clearly show working status and temperature changes. With its ergonomic handle design for a comfortable grip and compact, portable build, the SAG-55 is the ideal choice for professionals and DIY enthusiasts alike.
