Quest EDGE Cable-Free Noise Dosimeters - EG4, EG5

As the market leader in noise dosimeters, Quest is committed to offering the most innovative cable-free dosimeter on the market today.  The Edge is available with three models including the EG5 model for intrinsically safe environments.  With the Edge there's no bulky heavy dosimeter weighing you down. No more worrying about the cable interfering with your work.  Weighing in at a mere 3 ounces and featuring a thin, contoured shoulder mount, you'll barely notice the Edge at work. 

Even with its sleek size, you can display SPL, Dose, Lavg or Leq, TWA, Max Level, Min Levl, Peak Level, Exposure and Run Time while in run mode.  No other cable-free dosimeter on the market has this capability.  In addition, the display will show a visual indicator when exposure limits have been exceeded.

The Edge is available with 1- or 5-bay "EdgeDock" docking stations.  The dosimeters are placed on the EdgeDock and a red flashing light indicates that it is charging. 
A green solid light will appear when charging is complete.  The EdgeDock is also used to download data to 3M Detection Management Software.  Data is downloaded from each dosimeter through the EdgeDock and sent to a PC via the dock's USB Port.  Multiple EdgeDocks may be interfaced via a USB hub to the PC.

Battery life boasts over 60 hours of run time on the EG4 model and with 40 hour nominal without LED activated on the intrinsically safe EG5 model.  The rechargeable lithium polymer battery is the latest technology giving it superior run time.  In addition, the battery will only need to be replaced every 3 years, or possibly longer, saving you money over the life of the instument compared to other dosimeters on the market.

Key Benefits

1.  Convenient and efficient cable-free design eliminates the microphone cable and the potential to get in the way.

2. Thin, coutoured shoulder mount hugs your shoulder.  Small and compact frame offers superior comfort.

3. Rechargeable lithium polymer battery enables the Edge to have the longest battery life in the industry for cable-free dosimeters.

4. Offered with 1- or 5-bay "EdgeDock" docking stations for quick and easy recharge and data downloading.

5. Downloads to 3M Detection Management Software for analysis and management of measurement of data.

6. Two Models Available:  The EG4 and the EG5 models with dual dosimeters and data logging/time history.  The EG5 meets the American and International standards for Instrinsic safety.  (The EG3 model has been phased out).
