Rugged Kits: Ready to Run
To begin testing, simply remove the dosimeters from their rugged case and attach them to workers. After a shift, place the dosimeters back in the case where they will charge wirelessly and the data files can be downloaded. Built-in measurement of motion and bumps, combined with optional event audio recordings and 1/1 octave frequency analysis, provide additional data to help you understand what caused the noise.

What is the Spartan 730 noise dosimeter used for in the workplace?
The Spartan 730 is a personal noise dosimeter designed to measure worker noise exposure in the workplace.
It is worn by employees during a shift to capture real-time noise levels and calculate daily exposure values such as TWA and LEX,8h, helping organisations manage hearing risk and improve workplace safety.
The Spartan 730 helps organisations comply with the Health and Safety at Work Act 1974 and the Control of Noise at Work Regulations 2005 by accurately measuring employee noise exposure.
It meets recognised standards including:
• IEC 61252 for personal noise dosimeters
• ANSI S1.25 for occupational noise measurement
This ensures data aligns with HSE guidance (including L108), allowing employers to assess risk, implement controls, and demonstrate compliance with workplace noise regulations.
What measurements and data does the Spartan 730 provide?
The Spartan 730 captures all key workplace noise metrics, including:
• Leq, Lavg, Lmax, and Lpeak
• Time Weighted Average (TWA) and projected exposure values
• Dose percentage and daily exposure levels (LEX,8h)
It also logs data throughout the working day, providing detailed insight into task-based noise exposure and variations across shifts.
What features make the Spartan 730 suitable for workplace monitoring?
The Spartan 730 includes a wide range of practical features for Health & Safety professionals, including:
• Compact, wearable design for personal noise exposure monitoring
• Up to 40 hours battery life with rechargeable lithium-ion battery
• IP65-rated durability for use in harsh industrial environments
• High-resolution data logging for precise exposure tracking
• Built-in motion and bump detection to validate measurements and identify anomalies
It also offers an optional event audio recording upgrade, allowing users to capture short audio clips when noise thresholds are exceeded. This helps identify the source of high noise events, supporting more detailed analysis and targeted control measures.
How is workplace noise data analysed and reported?
The Spartan 730 integrates with G4 reporting software, enabling users to download, analyse, and generate clear professional reports.
Users can review exposure levels, compare results against legal limits, and produce documentation to support risk assessments, audits, and compliance with workplace health and safety regulations in the UK.
