The Edge Model
The “eg4” model features two virtual dosimeters with data logging. Once the parameters
are set and saved in the dosimeter, you can monitor two different dosimeters by a single
press of the Enter key. This will toggle you between the two dosimeters. The “eg3” model
is equipped with one dosimeter setting and will not data log (older model no longer
available).

Virtual dosimeters
You can monitor and log noise studies by enabling two different parameter settings in one
dosimeter, also referred to as “virtual dosimeters”. For instance, you may want to set one
dosimeter to log using the OSHA HC (Occupational Safety and Health Administration -
Hearing Conversation) parameters and also monitor noise with the OSHA PEL
(Occupational Safety and Health Administration Permissible Exposure Level) settings.
A few scenarios of virtual dosimeters include:
Industrial noise control
Hearing conservation compliance
Work site assessments
Personal noise verification
Military applications
Regulatory compliance (i.e., OSHA, MSHA, IEC, ACGIH)
