Center CENTER 320 - Sound Level Meter 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. Sound_Meters
Center CENTER 321 - Sound Level Meter (PC Interface) 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. Sound_Meters
Center CENTER 322 - Sound Level Meter (Datalogger) If one needs long time on site sound monitoring, CENTER 322 will be the choice. With its build in 32000 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. Sound_Meters
Center CENTER 390 - Sound Level Meter (Single Range, Datalogger) Our advance sound level meter CENTER 390 fully complies with IEC61672-1. This meter has only one measuring range and it is extending from 30db to 130db that is full 100db. The operator will not have to worry about which range to use like in the 3 or 4 range models and neither about signal latency in auto range models. This unit is also a data logger and it is equipped with manual storing capability which can store 99 sets of data and can be readout from unit or through PC. Sound_Meters
Center CENTER 325 - Compact Size Sound Level Meter CENTER 325 is our entry level sound level meter. We have tried to keep as much feature as possible and on the same time reduce the system complexity as much as possible. 325 is the result. Sound_Meters
