Sound Level Meter - The Low Cost CR303

• Type 2 to IEC 60651 and ANSI S1.4 sound level meter standards.
• Includes a factory Calibration Certificate.
• "A" frequency weighting.
• RMS "Fast" time weighting.
• LCD display updated every second.
• Small and light in an ABS plastic case.
• "Max Hold" button.
• Two measurement ranges giving 35 dB(A) to 130 dB(A).
• Powered by a single 9V battery (type 6LR61, PP3).

This sound level meter is designed to be easy to use and cost effective to buy, while still meeting the demanding requirements of the IEC and ANSI sound level meter standards. Its lightweight construction also make it ideal as an instrument to keep handy for those unplanned for noise measurement needs.

The Max Hold (LAFmax) feature holds the highest sound level that the meter has measured, making it easy to determine the level of the loudest noise.

In use, the meter could hardly be easier to operate. Just switch it on to the Low range for relatively quiet areas and High range for noisier environments (factories for example). The sound level is shown on the large LCD display.

If you also need an acoustic calibrator and a windshield then the Measurement Kit is the ideal choice. It includes the sound level meter, an acoustic calibrator, windshield and carrying case.
