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.
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.
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.
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.
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 31 is our proposed full time environmental monitoring system. Its detachable probe and can be verify or calibrated through optional signal extending cable and our standard calibration cell. Monitoring limit can be set to this unit. Once the environment condition is out of the setup condition, the unit will send the warning with buzzing and blinking display.
CENTER 318 is our new hygro thermometer. Its detachable probe can be easily extended with option extending cable or the operator can directly connect the probe to the base unit to form standard humidity tester. It is also a data logger with 16000 data memory. With the stand on the unit, it is easy to set to anywhere for data collecting.
