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 310 is our standard series humidity temperature meter. By applying high performance sensor, these testers have rapid response and long time stability.

CENTER 380 Refrigerant Leakage Detector is the perfect tool for maintaining the air-condition or a cooling system with compressor and Refrigerant. This unit used newly developed semi-conductor sensorwhich is extremely sensitive to variety of general used refrigerant.

Category: Light_Meters

Our light meter CENTER 337 can be used in working environmental check, illumination design verification and other light monitoring applications. If the user turns on this unit with the cap on, it will zero the reading automatically. With the sensor on the top of tester, this meter can easily operate with single hand. The sensor is compensated with filter to make the response close to human eye. The light source angle is also compensated according to its cosine function.

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 382 is a perfect tool for air-condition system maintaining. The operation interface is intuitive with button, light bar and sound. The “air sucking system” greatly help the sensitivity and response time. The “auto-reset”  function can help the operator to distinguish the leaking spot among the already spreading refrigerant while maintain high sensitivity.

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.
