What is the TSI Quest Edge 4 Plus used for?
The Edge 4 Plus is a compact personal noise dosimeter used for OSHA 1910.95 and OSHA 1926.52 noise exposure assessments, hearing conservation program baseline measurements, and occupational noise compliance surveys. It measures Lavg, Leq, Lmax, Lpk, TWA, and dose without octave band analysis.
What is the difference between the Edge 4 Plus and the Edge 5 noise dosimeters?
The Edge 5 adds 1/1-octave band frequency analysis to the Edge 4 Plus capabilities. For standard OSHA noise compliance surveys and hearing conservation program requirements (dose, TWA, Lmax), the Edge 4 Plus provides all necessary measurements at lower cost. The Edge 5 is required when octave band data is needed for engineering noise control, audiometric evaluation support, or frequency-specific hearing protector NRR selection.
Is the Edge 4 Plus intrinsically safe?
Yes. The Edge 4 Plus is intrinsically safe (MSHA, ATEX, CSA, IECEx certified) for use in hazardous classified locations, including mining, oil and gas, and chemical processing environments.
How long does the Edge 4 Plus battery last?
The Edge 4 Plus provides approximately 40 hours of runtime on a single charge, supporting multi-shift sampling campaigns without daily recharging.
How does the Edge 4 Plus transfer data?
Data is transferred wirelessly via Bluetooth to TSI's Detection Management Software (DMS) or Quest Suite software, which generates OSHA-compliant exposure reports.
What is the Edge 4 Plus rental rate from RAECO Rents?
Contact RAECO Rents at 866-736-8347 for current Edge 4 Plus daily and weekly rental pricing. Rental includes the dosimeter, windscreen, calibrator, DMS software, and case. Multiple units available for simultaneous multi-worker surveys.
