Multi-channel heavy metal detector

The multi-channel heavy metal detector comprises a rack, an operation door and a luminosity probe, detection channels are uniformly arranged on the rack, the luminosity probe is installed at the top end of the interior of each detection channel, and a carbon fiber electric heating piece and a temperature sensor are installed on the inner side wall of each detection channel. The operation door is slidably connected to one side of the detection channel. The performance of the device is optimized by installing the detection channels, the man-machine touch screen and the like, on one hand, six groups of independent detection channels are arranged on the device, so that the device can complete detection of six groups of independent samples at a time, the function of multi-channel detection is achieved, and the processing efficiency is improved; on the other hand, a loudspeaker and a man-machine touch screen are installed on the device, so that a user can conveniently set detection parameters and retrieve detection
