PCE Class 2 Decibel Sound Meter - PCE-428
The PCE 428 Class 2 Decibel Sound Meter (25 - 136dB) meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-1997 requirements. This portable, high-accuracy sound level meter has a large easy-to-read light-up LCD screen that displays the sound pressure level (SPL) numerically & graphically in real time. Thanks to octave band filtering, even the slightest difference in frequency is detected.
This handheld sound meter also functions as a data logger, recording measurements at an adjustable interval from 1 s - 24 h and storing the recorded measurement data to a micro SD card. The card can be removed from the meter and inserted into a PC. Alternatively, the decibel meter can be connected directly to a PC via USB. The provided PC-compatible software allows for quick and easy data analysis.
This device measures from 25 - 136 db(A) at a frequency of 20 Hz - 12.5 kHz. The meter features A, B, C and Z frequency weightings as well as fast, slow and impulse time weightings. The PCE-428 decibel meter is commonly used by professionals to ensure compliance with environmental noise regulations and workplace noise permissible exposure limits.

Maintenance Tips
- Keep the microphone capsule clean and free from dust by using a soft brush or air blower only.
- Store the sound meter in its protective case to avoid shock damage and sensor misalignment.
- Avoid exposing the device to extreme humidity, moisture, or direct sunlight to protect internal electronics.
- Regularly check calibration status and recalibrate using a certified acoustic calibrator when required.
- Ensure battery is charged and replace or recharge it as needed to maintain measurement accuracy.
- Handle the microphone carefully—do not touch or apply pressure directly to the sensing element.
- Inspect cables, connectors, and mounting points for wear or loose connections before each use.
- Keep firmware (if applicable) updated for improved measurement stability and compliance with Class 2 standards.
