Being light weighted and extremely compact makes this the world’s smallest class 1 sound level meter. Very portable as it will fit in your pocket, yet it ensures you the reliability and precision required for a class 1 measurement.

The perfect all-purpose tool for simple analysis of noise at work, environmental noise and basic product noise determination.
