CRY2831 Class 2 Sound Level Meter, 29-138dB, Calibration Certificate | IEC 61672-1:2013 Class 2, A /C /Z Weighting, F /S Time Weighting, 20Hz-12.5kHz, Industrial Noise Measurement

Features

• IEC 61672 TYPE 2 PROFESSIONAL SOUND METER: CRYSOUND 2831 sound level meter meets international standards of IEC 61672-1:2013 Class 2, features self-developed condenser microphone of high accuracy, DC and battery powered, LCD display, wide measurement ranges of 29dB to 138dB and 20Hz-12.5kHZ, IP54 rated, exclusively designed for users who need a real working noise meter, not a casual decibel gadget, deal for professional spot checks in workplace, facility, environmental and industrial settings.
• 29dB-138dB WIDER RANGE SOUND DECIBEL METER: Our professional sound level meter captures the faintest and loudest sounds, extending down to 29dB(ideal for capturing quiet libraries or late-night environments)) and up to 138dB(easily handling louder machinery or live events). Whether it's the silence of a pin drop or a deafening roar, it maintains precision.
• 20Hz-12.5kHz EXTENDED FREQUENCY RESPONSE: With a frequency measurement range up to 12.5kHz, our digital decibel meter reader significantly surpasses regular 8kHz limit. This allows it to accurately capture high-frequency mechanical noise, electronic device squeals, and specific industrial sounds, providing richer data for users .
• A&C&Z FREQUENCY WEIGHTING and F&S TIME WEIGHTING: Go beyond basic dB readings. A-weighting is ideal for environmental noise, C-weighting captures peak industrial sounds, and Z-weighting provides flat, unweighted measurement. Fast mode captures rapid, transient noise like traffic, while Slow mode delivers stable readings for continuous noise sources. Designed for technicians, EHS teams, facility managers, and inspectors who require accurate, reliable and application-specific measurements.
• SELF-DEVELOPED MICROPHONE FOR HIGH PRECISION: This industrial sound level meter is equipped with our self-developed 1/2'' condenser microphone, delivering 1.5dB accuracy and a noise floor below 25dBA, ensuring reliable and precise acoustic measurements.
• BUILT FOR THE FIELD: Engineered with an IP54-rated enclosure and AC/DC dual power supply, this device is protected against dust ingress and low-pressure water jets, making it ideal for demanding industrial and outdoor environments. It operates reliably in extreme temperatures ranging from -20C to 60C (-4F to 140F), ensuring consistent performance in freezing cold or scorching heat.
