This pen-type sound decibel meter is a compact and portable device designed for quick and accurate noise level measurements in everyday and professional environments. Equipped with a high-sensitivity condenser microphone, the device accurately measures sound levels across a wide decibel range (30~130dB). It is useful for preliminary noise assessments, routine inspections, and personal awareness of noise exposure in everyday environments..
Noise Level Meter Adopts Backlit Display
- Clear Readability in Low-Light Conditions. Sound level meter adopts LED backlit display ensures the measurement values are clearly visible in dark or dim environments, such as factories, workshops, machine rooms, construction sites, or nighttime outdoor inspections. Unlike non-backlit screens, the LED backlight eliminates the need for external lighting, improving efficiency and reducing eye strain.
- Enhanced Usability for Field Applications. Many noise measurements are taken in changing environments where lighting conditions are unpredictable. The LED backlight allows consistent usability whether indoors, outdoors, during daytime, or at night. This versatility makes the device suitable for environmental monitoring, occupational safety checks, and household noise testing.
Noise Meter With Condenser Microphone
- High Measurement Accuracy. A condenser microphone is highly sensitive to sound pressure changes, allowing the pen-type sound level meter to capture even subtle variations in noise levels. This results in more accurate and reliable measurements, especially when monitoring low-level or fluctuating sounds. Compared with ordinary microphones, condenser microphones provide better linearity across the measurement range.
- Excellent Signal Stability. Thanks to its stable electrical characteristics, a condenser microphone generates consistent output signals with minimal distortion. This stability helps the sound decibel meter reduce measurement errors caused by environmental interference, ensuring dependable performance during long-term or repeated measurements.
Applications
SISCO's digital decibel meter is widely used to measure and monitor noise levels in various environments, ensuring compliance with safety standards and protecting hearing. In schools, it helps assess classroom acoustics, monitor playground or cafeteria noise, and create a conducive learning environment by identifying areas with excessive sound. In factories, it is essential for monitoring industrial noise, ensuring workers are not exposed to harmful decibel levels.

Q1: What is a noise detector?
A1: Noise tester is an instrument used for noise detection and testing in public places such as work sites and squares. Factory noise monitoring Noise pollution is one of the environmental pollutions that have a greater impact. Higher decibel noise can even cause serious damage to people's eardrums and cause deafness. The application of the noise tester can provide the decibel that the noise reaches in order to take relevant measures to control and reduce the noise.
Q2: What are the different decibel ranges?
A2: Decibel (dB) ranges are used to measure sound intensity, with each range corresponding to common noises and potential hearing effects. 0–30 dB represents very quiet sounds, such as a whisper or rustling leaves, generally safe for prolonged exposure. 30–60 dB covers normal conversation, office noise, or background music, posing minimal risk to hearing. 60–85 dB includes busy traffic, vacuum cleaners, or loud music; prolonged exposure above 85 dB can start causing hearing damage. 85–100 dB represents heavy traffic, motorcycles, or loud concerts. 100–120 dB includes chainsaws, car horns, or rock concerts, which can cause immediate discomfort and potential hearing loss with short exposure. Above 120 dB, like sirens or jet engines, can lead to pain, permanent hearing damage, or eardrum rupture almost instantly.
Q3: How to maintain a sound level meter?
A3: To maintain a sound decibel meter, handle it carefully and avoid dropping it, as impacts can affect accuracy. Keep the microphone clean and free from dust or moisture; use a soft brush. Store the device in a protective case when not in use and avoid exposure to extreme temperatures or humidity. Regularly calibrate the meter using a certified acoustic calibrator to ensure precise readings. Replace batteries promptly to prevent leakage. Avoid using it near strong electromagnetic fields or vibrating machinery, which may interfere with measurements.
Tips: How lightweight is this pen-type sound decibel meter?
Weighing about 80 grams (gross weight), a pen-type sound decibel meter is exceptionally lightweight—about the same as a medium-size egg. You'll barely notice it in your pocket or bag. Its featherlight weight makes it ideal for on-the-go measurements in classrooms, work sites, concerts, or field surveys without fatigue. Despite its lightness, it feels solid and easy to hold in one hand for extended periods. If you're used to bulkier meters, this noise meter feels almost weightless, blending portability with practical everyday use.
