Product Description
The Testo 816-1 is a professional digital sound level meter engineered for high-precision noise level measurement across industrial workspaces, public sectors, and manufacturing infrastructures. Fully compliant with IEC 61672-1 Class 2 and ANSI S1.4 Type 2 international engineering standards, this device integrates a high-capacity internal data logger capable of archiving up to 31000 measurements. It features switchable frequency weightings (A/C) and dual time-weighting constants (FAST/SLOW) for comprehensive acoustic validation via dedicated PC analytics software.
Industry Applications
- Occupational Health and Safety (HSE) Audits: Continuous tracking of long-term workplace noise exposure to prevent industrial hearing hazards.
- Environmental Noise Immission Control: Field monitoring of environmental noise pollution caused by vehicle traffic, localized machinery, and public events.
- Industrial Manufacturing Quality Assurance: Testing acoustic emission boundaries on production machinery and HVAC installation platforms.
