ATP Sound Level Meter with A & C Weighting, 40-130dB

The ATP Sound Level Meter is a professional-grade instrument designed for accurate and reliable noise measurement across a wide range of environments. It features a high-sensitivity electret condenser microphone that provides virtually instantaneous readings, updated every 0.5 seconds, on a large, clear hi-contrast LCD display for excellent visibility in various lighting conditions.

This versatile meter offers four distinct measuring ranges: 40-70dB, 60-90dB, 80-110dB, and 100-130dB. It can operate in either auto-ranging mode for ease of use or manual range selection for precise control over specific decibel levels. The device supports both A and C frequency weightings, allowing you to tailor measurements to different applications, from environmental noise assessment to industrial machinery analysis.

Key functionalities include selectable slow or fast response times to match the characteristics of the sound being measured. The max hold function captures and displays the highest recorded sound level, while the data hold feature freezes the current reading for easy recording. A dynamic quasi-analogue bargraph, updating every 50 milliseconds in 1dB steps, provides a real-time visual indication of sound level fluctuations.

Designed for user convenience, it features soft-touch, non-slip rubber buttons and includes practical indicators for low battery and an auto power-off function to conserve energy. The unit is supplied complete with a battery and instructions for use, making it ready for immediate operation right out of the box.
