When making outdoor noise measurements, sensitive microphones and noise
measuring equipment can be exposed to all types of weather including rain, dew,
wind and heat. Protect your equipment and data from the negative effects of
exposure to weather by using an Environmental Protection System, EPS. Our EPS
products allow a sound level meter to be placed in a protective case and connected
to an outdoor microphone system through a watertight orifice using an extension
These systems provide rechargeable battery power to your noise monitoring
equipment for up to 4 weeks, while also protecting from damage or measurement
error due to dirt or moisture. Whether you need a system that is small and
portable or one that will provide extended continuous monitoring in remote locations,
we have an EPS product to fit your need.
For protecting you outdoor microphone and preamplifier we offer a new universal
protection shroud. The EPS2116 has a built-in rain screen and can be mounted on
a camera tripod (1/4-20 thread) or a ¾” NPT (ISO 228-G ¾) pipe thread. When
combined with the Model 831 or SoundExpert LxT sound level meter, digital correction
filters allow for the selection of free field, random or 90 degree response
from your sound level meter for a high level of measurement flexibility.
Determining the EPS products that are suitable for your application will depend on
the weather conditions, accessibility to the site, duration of your measurements,
and more. See the table below to help you select the most appropriate products.
