Overview
The Personal Noise Exposure Meter DB22-600E is an intelligent noise measurement instrument that can measure A-weighted sound pressure level, equivalent continuous sound level Leq, as well as sound exposure level LAE and noise exposure level E. It can be widely used for monitoring various environmental noise, evaluating industrial hygiene noise in labor protection, and measuring and analyzing industrial noise from various machines, vehicles, ships, electrical appliances, etc.
Product Details
Personal noise exposure meterDB22-600E【Product Application】
1. Occupational Health and Safety Compliance (Core Application)
Regulatory compliance assessmentVarious countries around the world, including China's Occupational Disease Prevention and Control Law and Occupational Exposure Limits for Hazardous Factors in the Workplace, have set limits for workplace noise exposure (such as 85 dB (A) or 90 dB (A) as the 8-hour time weighted average Action Level). This instrument is used for measurement and evaluation in accordance with the lawtool.
2. Specific application scenarios in the chemical industry
The "standard" equipment of occupational health technical service institutions is used for regular occupational disease hazard factor detection in chemical plants.
3. Data management and trend analysis
data recordingContinuously record equivalent continuous A-level (Leq), exposure percentage (% Dose), peak noise, and other data to generate a complete exposure history file.
Report GenerationExport data through software, generate exposure reports and trend charts that comply with regulatory requirements, for reporting to higher-level agencies (such as safety supervision and health departments) or internal archiving.
