CENTER 320

Our standard sound level meter CENTER 320 has a wide dynamic range from 30 to 130 dB. It has different frequency weighting A and C to respond to human sense or machine monitoring purposes. For different sound pattern, it also supplies Fast and Slow time constant setting. Analog output is also provided for other use.

CENTER 321

CENTER 321 is our newly designed sound level meter. With all the functions 320 can provide, we had changed something in new designed back light LCD. We had added fast analog bar with peak hold two second in this tester. An auto range function is added for the tester to choose one proper range for measuring by the tester itself. RS232 interface is also added to provide real time data to the computer.

CENTER 322

If one needs long time on site sound monitoring, CENTER 322 will be the choice. With its build in 32'000 records deep memory, it can gather all the data you need just by this tester and a tripod. After the data is collected, the user can download the data to the computer at his convenient place.

CENTER 325

CENTER 325 is our entry level sound level meter. We have tried to keep as much as possible and on the same time reduce the system complexity as much as possible. 325 is the result.
