The Spartan™ model 730IS intrinsically safe noise meter is designed to safely perform noise exposure measurements, even for workers in potentially explosive environments, such as industry. petrochemical industry and pharmaceutical production.


I. Specification of Spartan™ 730IS intrinsically safe noise level machine

  • Spartan™ 730IS intrinsically safe noise dosimeter Simple design and intuitive setup make worker noise dosimeter easy and quick. With the Spartan-IS, control setup and test measurements on the instrument itself or directly from the Larson Davis
  • Atlas™ mobile app. All necessary tasks can be completed from your iOS® or Android® device.
    The Spartan™ 730IS-PK Series Content Safety Meters are designed to safely perform noise exposure measurements, even for workers in potentially explosive environments, such as in the petrochemical industry and export products.

II. Outstanding applications of the 730IS wireless safety noise meter

  • Measurements of workers’ noise exposure
  • Research on risk reduction
  • Measuring compliance with OSHA, ACGIH, ISO 9612 and EU Directive 2003/10/EC.

III. Spartan™ 730IS intrinsically safe noise dosimeter – Simplify sound measurements

  • ATEX, UL 913, IECEx, FCC, CAN/CSA C22.2 Approved
  • Wireless operation, charging and Bluetooth low energy communication (available without Bluetooth for regions without. radio)
  • Spartan™ 730IS intrinsically safe noise dosimeter with full control and direct monitoring via the LD Atlas™ app*
  • Download and view measurements, generate reports and share annotated data from your mobile device
  • Built-in motion and collision detection
  • Automatic dosimeter calibration.
  • Steps to take:
    – To begin testing, simply remove the dosimeters from the sturdy carrying case and attach them to the worker.
    – After work, put the dosimeters back in case they will charge wirelessly. The G4 LD Utility software provides another option for controlling the testing process.
    – With all the functionality of the LD Atlas mobile app, G4 LD Utility adds the ability to complete a “what if” analysis to model potential changes and determine the impact of choices different data.
    – LD Atlas offers low-energy Bluetooth interference-free monitoring, ensuring that you get the valuable data your users need the first time.
    – When the test is complete, the Spartan-IS communicates with the LD Atlas to download the data, which can be viewed directly from a phone or tablet. Generate reports, including entire data files, from the mobile interface before sharing via email.
    – For high security, radio-free zones, optional 730-NBT without Bluetooth is available and allows setup and data download via G4 LD Utility software via USB connection.
