Sound Level Meters

Class 1 or Class 2 Sound Level Meter?

Sound Level Meters (SLM) are divided into two Classes, Class 1 and Class 2; both have the same functionality but different tolerances for error. Class 1 meters have a tighter tolerance (“precision meter”) than the lower cost Class 2. This applies to both the instrument and its associated calibrator. Most standards/regulations permit the use of “at least a Class 2 instrument”. These Sound Level Meters can also function as a dosemeter.

It is recommended that the instrument's calibration is checked and adjusted where necessary using an Acoustic Calibrator before readings are taken, and calibration rechecked after taking readings, to confirm the validity of the results.

Class 2 Integrating Sound Level Meter

This meter uses using simple, logical keys to immediately display the required information. As this is a non-data logging meter the results will have to be manually recorded.

Class 1 and Class 2 Data Logging Sound Level Meters

These meters have an easy to follow menu system and clearly marked keys, all designed to make the meter simple to use. A clear backlit LCD with large digits and a bargraph display show the changes in sound level as they occur.
