The CHUERA-315D is a 150W intelligent soldering station designed for lead-free soldering applications. It combines high-frequency eddy current heating with microcomputer temperature control to support rapid heating and temperature recovery. The large LCD displays real-time and set temperatures simultaneously, while adjustable upper and lower alarm limits help identify temperature deviations. Additional features include password-protected temperature settings, digital calibration, automatic sleep and shutdown, and a replaceable plug-in heating core.
