Brief introduction: HS6298C multi-functional noise analyzer is not only a general sound level meter for measuring the weight sound level of exponential time meter, but also an integral average sound level meter for measuring the time average sound level and an integral sound level meter for measuring the sound exposure. Its performance meets the requirements of GB/T3785 and iec61672-2002 standards for two-level sound level meters, and its sensitivity to radio frequency field belongs to category X. This instrument adopts advanced digital detection technology, which has the advantages of high reliability, good stability and wide dynamic range. Dot matrix character liquid crystal display, easy operation for users, battery power supply, measurement results stored in the instrument for a long time, through the rs-232 interface in the field or after the micro-printer printed out or sent to the computer for processing. This instrument is compact in structure, beautiful in shape and has many functions. It can be used for measuring environmental noise, labor protection, industrial hygiene and industrial noise of various machines, vehicles, ships and electrical appliances. Features: 1. With integral and statistical functions, there are 500 groups for a single group and 8 groups for 24 hours. The stored data can be accessed and printed. The whole time measurement pause time can check the collected data. Can perform statistical measurement of Leq, LAE, Ln, etc. 2. Replacing some traditional sound level meters with digital detection technology, the stability and reliability are greatly improved. 3. 8X2 dot matrix character LCD display is adopted for clear and intuitive display. 4. It can be connected to the computer or printer through rs-232 interface, which can display, print output, or send to the computer for analysis and processing. Technical parameters: 1.
