Sound level meter SPMTWO
Measure and analyze sound
The powerful instrument for stand-alone sound level measurements. In parallel, the system collects and stores data and automatically transfers them to up to 2 independent servers. At the same time, the noise level measurement can be monitored from your workplace or mobile device. The SPMTWO sound level meter is used for rail, road and air traffic as well as on construction sites, at events and in industrial plants.

Service
How is the product maintained?
We recommend an annual recalibration and adjustment for all our sensors to be able to guarantee the exact functionality. We calibrate our sensors with state-of-the-art measurement technology in our in-house calibration laboratory. Our test equipment is one of the most accurate references in measurement and control technology. The test results are summarised in a factory calibration certificate in accordance with DIN EN ISO/IEC 17025:2018-03.
