Class 2 Sound Level Meter SC102

Class 2 integrating sound level meter with measurement protocols

The SC102 is more than just an acoustic measurement instrument as it not only performs measurements but also the checks and calculations indicated in the standards, to obtain the final result on-site. It is the first integrating sound level meter with measurement protocols, which greatly simplifies the process of obtaining results. It guides the user step by step in performing the measurements. The SC102 adapts to each user's needs as it allows the selection of the measurement protocol for the following applications: MOTOR VEHICLES, ACTIVITIES AND NEIGHBORHOOD, OCCUPATIONAL RISKS, MACHINERY (PRESSURE), MACHINERY (POWER) or SOUND LEVEL METER (CLASSIC). The user only has to follow the procedure indicated by the SC102 to obtain the final result. Measuring noise has never been so easy!
