Online total nitrogen detection device based on Internet of Things

The online total nitrogen detection device comprises a base, detection equipment and an Internet of Things module, the detection equipment is fixedly installed on the upper surface of the base, the Internet of Things module is fixedly installed at the position, close to the detection equipment, of the upper surface of the base, and the Internet of Things module is electrically connected with the detection equipment. A containing table capable of moving back and forth to facilitate detection is arranged between the upper portion and the lower portion of the base, and supporting structures capable of providing a certain elastic buffering effect are symmetrically arranged at the positions, close to the bottom end, in the containing table at equal intervals. The device effectively solves the problems that in the prior art, only single-group detection can be carried out, and test tubes are prone to being damaged due to vibration, is suitable for multi-group detection, is easy and convenient to operate, meanwhile,
