Intrinsically Safe Noise Dosemeter System

The Intrinsically Safe Noise Dosemeter System is a precision instrument developed for accurate and reliable noise exposure measurement in hazardous or explosive environments. Designed for industries such as mining, petrochemical, oil and gas, and manufacturing, it ensures compliance with international safety standards while delivering precise data on worker sound exposure. Its gold-coated metal casing provides durability and inertness, ensuring complete safety and reliability in volatile environments.

How It Works

Each dosemeter is a self-contained, cable-free unit that records personal sound exposure without the need for external microphones or controls, eliminating the risk of tampering or damage during use. The Reader Unit manages all key operations, including programming, calibration, data logging, and transfer via wireless infrared communication. Its integral acoustic calibrator ensures measurement accuracy before and after every session, complying with global occupational noise standards. The system automatically calculates Daily Exposure (LEP,d) and Time Weighted Average (TWA) in line with both European and US regulations, while comprehensive time-history data allows users to identify noise peaks throughout the workday or week.

Key Benefits

• Certified for operation in explosive and flammable environments
• Complies with ATEX, IECEx, EEx, FM, SIMTARS, and UKEX intrinsic safety standards
• Gold-coated metal casing for inertness and durability in harsh conditions
• Shoulder-mounted via a leather clip-on strap for comfortable, secure wear
• Monitors worker noise exposure over a full workday, shift, or week
• Self-contained, cable-free design prevents interference or tampering
• Captures all essential parameters: LAeq, LEP,d, % Dose, and TWA
• Records C-weighted peak time history for impulsive noise assessment
• Integral acoustic calibrator ensures accurate pre/post-measurement verification
• Wireless Reader Unit with a large backlit LCD for live parameter display
• License-free AnalyzerPlus software for detailed analysis and reporting

Installation & Operation Overview

The Intrinsically Safe Noise Dosemeter is worn on the shoulder using a secure leather strap and continuously monitors personal noise exposure. Once configured through the Reader Unit, the device operates autonomously and requires no user interaction during measurement. Calibration is performed automatically before and after each recording session, ensuring precision and compliance with international standards. Collected data can be downloaded to AnalyzerPlus software, where results are presented in clear, regulation-ready reports.
