        Online detection&Alarm device for dust noise concentration is a device developed and produced by Shenzhen Boyunchuang Environmental Science &Technology Co., Ltd. for the detection of various dust and noise pollution environmental concentration in the workshop recently. It is mainly used for online measurement of dust and noise concentration in the workshop and warning of exceeding standards. Prevent the dust concentration is too high to be harmful to the health of workers or cause explosion accidents due to the concentration is too high to endanger life safety. It is widely used in flour mill, cement factory, feed mill, polishing factory, furniture factory, wood factory, plastic factory and other areas where it is easy to produce dust.

Ii. Noise index

Noise in industrial workshops refers to the noise produced when mechanical equipment is in operation. According to the characteristics of the noise source, it can be divided into airflow noise, mechanical noise and electromagnetic noise. In 1979, the Ministry of Health and the State Administration of Labor issued the "Sanitary Standard for Noise in Enterprises" (trial), which stipulated that the noise in the workshop and the workplace should not exceed 90dB in 8h continuous work. For every 3dB increase in sound level, the operating time will be halved, but the maximum shall not exceed 115dB. The standard protects the hearing of workers.
