In the field of solid content detection, the contradiction between measurement accuracy and measurement speed has not been solved; In view of this situation, Shenzhen Fenxi Instrument Manufacturing Co., Ltd. provided an instrument with a dry structure for rapid determination of solid content. The solid content detector adopts German HBM weighing system to ensure accurate weighing; Annular timely tungsten halogen infrared heating source, fast drying samples; Compared with the international oven heating method, the annular timely tungsten halogen infrared heating can dry the sample evenly and quickly at high temperature, and the surface of the sample is not easy to be damaged. The detection results are consistent with the national standard oven heating method, and the detection efficiency is much higher than that of the oven heating method. The intelligent operation requires only a few minutes for general samples to be determined. The solid content detector has been protected by national intellectual property rights (patent number 201420090168.1), and it is a new type of rapid detection instrument.
