Price range: $11.99 through $18.99

 824 series Sound Meter from Ruoshui/VICTOR provides professional-grade noise measurement in two practical configurations. Model 824 measures 50~130dBA and 50~130dBC with both A and C frequency weightings, while the compact 824C covers an extended 30~130dBA range – ideal for quieter environments such as libraries, studios, and residential areas. Both models achieve ±1.5dB accuracy across a 31.5Hz to 8.5kHz frequency response, capturing the full range of human-perceptible sound.

Key features include selectable Fast (125ms) and Slow (1s) dynamic characteristics, MAX hold for peak level capture, and a professional ½-inch condenser microphone for reliable sensitivity. The sampling rate of 2 times per second provides responsive real-time feedback without display clutter. Each Sound Meter operates on a standard 9V battery and includes low-battery indication, ensuring you are never caught off guard during critical measurements.

  •  824 series Sound Meter offers two models to match your exact needs. The 824 covers 50~130dBA and 50~130dBC with dual A/C weighting, while the 824C provides an extended lower range of 30~130dBA – perfect for quieter environments like libraries and recording studios.
  • Exceptional ±1.5dB accuracy – whether you are checking factory machinery noise or classroom ambient levels, this Sound Meter delivers reliable, repeatable measurements you can trust for compliance reports and noise control decisions.
  • Wide frequency response from 31.5Hz to 8.5kHz – capturing low-frequency rumble and high-frequency chatter alike. The 824 series Sound Meter accurately represents real-world noise across the human hearing spectrum, making it suitable for industrial hygiene, audio tuning, and environmental assessments.
  • Fast and Slow dynamic characteristics – switch between Fast (125ms) for capturing sudden impact noises or Slow (1s) for averaging fluctuating sounds. This Sound Meter adapts to your measurement scenario, whether you are measuring passing trucks or continuous HVAC hum.
  • A-weighting and C-weighting on model 824 – A-weighting mimics human ear response at moderate levels, while C-weighting captures low-frequency energy. The 824 Sound Meter lets you choose the right weighting for workplace noise regulations (A) or mechanical diagnostics (C).
  • Model 824C extends the lower range to 30dB – ideal for libraries, bedrooms, theaters, and recording studios. This Sound Meter captures whisper-quiet environments that standard 50dB-minimum units miss, giving you true low-noise measurement capability.
  • ½-inch condenser microphone – professional-grade acoustic sensor ensures sensitivity and stability over years of use. The 824 series Sound Meter uses the same microphone type found in much more expensive instruments.
  • 2 times per second sampling rate – responsive enough to follow changing noise levels without overwhelming the display. This Sound Meter provides real-time feedback as you move through a space or adjust equipment.
  • Clear unit display and low battery indication – always know what you are measuring and when to change the 9V battery. The 824 Sound Meter eliminates guesswork with intuitive icons and a well-organized LCD.
  • MAX hold function – capture the highest noise level during a measurement period. This Sound Meter is perfect for identifying peak impact noises, maximum machine output, or the loudest moment in a venue.
  • Compact and lightweight – model 824 measures 200×63×30mm and weighs ~210g; model 824C is even smaller at 130×57×30mm and ~173g. The 824 series Sound Meter fits easily in a tool bag, desk drawer, or carry-on luggage for on-the-go assessments.
  • Durable construction for field use – operating temperature from 0~40°C and humidity 10~80%RH. This Sound Meter performs reliably in factory floors, outdoor noise surveys, and building service inspections.
  • Safe storage conditions – store from 0~60°C and 10~70%RH. The 824 Sound Meter survives seasonal temperature swings in vehicles or maintenance closets without degradation.
  • Standard 9V battery power – globally available and inexpensive. No special charging cables or proprietary packs for this Sound Meter – swap batteries in seconds and continue working.
  • Applications across multiple environments – factories, offices, libraries, traffic roads, homes, audio venues. The 824 series Sound Meter is the versatile tool for safety officers, facility managers, HVAC technicians, acoustical consultants, and hobbyist audio enthusiasts.
  • Easy one-hand operation – intuitive button layout for power, weighting selection, fast/slow toggle, and MAX hold. This Sound Meter can be operated while holding a probe or ladder – no complex menus to navigate.
  • Why upgrade from basic noise indicators? Basic sound checkers give rough estimates. The 824 series Sound Meter delivers calibrated ±1.5dB accuracy, professional frequency response, and true weighting filters. When you need numbers that matter for OSHA, EU, or local noise regulations, this is the tool.
  • Model comparison made simple – choose the 824 for A/C dual weighting and standard 50~130dB range. Choose the 824C for extended low end (30~130dBA) in a more compact body. Both models deliver Sound Meter excellence with the same ±1.5dB accuracy and 31.5Hz~8.5kHz response.
  • Backed by Ruoshui / VICTOR quality – a trusted name in test and measurement. The 824 series Sound Meter undergoes rigorous calibration before leaving the factory, ready for your most critical noise assessments.
