01MEASURING TOOLS & SENSORS
Precision in every decibel
A compact instrument for those who listen closely, this device transforms ambient air into quantifiable data. It sits comfortably in the hand, ready to assess the acoustic character of any room or workspace.
Designed for engineers, auditors and curious homeowners, it captures sound levels with high sensitivity. The unit records peak values and tracks temperature, providing a complete picture of the environment.
02DESIGN
A focused interface for clear data
The face of the meter is dominated by a four-digit digital display, ensuring that numerical readings are legible even in low light. This clarity is essential when monitoring subtle changes in audio levels. The layout prioritises the primary function, allowing the user to focus on the fluctuating numbers without distraction.
FUNCTION
Recording peaks and tracking conditions
Beyond simple reading, the device holds maximum and minimum values, useful for identifying transient noise spikes. A built-in temperature sensor measures ambient heat from -10°C to 50°C, adding context to the acoustic data. Automatic or manual shutdown options help conserve power during extended field sessions.
