When making outdoor noise measurements, sensitive microphones and equipment can be exposed to all types of weather including rain, dew, wind and heat. Protect your microphones from potentially adverse environment conditions that can lead to incorrect measurement by using the EPS2116.
The EPS2116 is designed to work with almost any combination of 1/2 inch precision microphone and preamplifier and provides for easy acoustic calibration to make sure your measurements are accurate. Because the EPS2116 is designed with an integral rain shield it will keep your microphone dry even in a driving rain.
Combine the EPS2116 with the Larson Davis PRM2103-FF outdoor microphone and Model 831 sound level meter to produce an ideal outdoor noise measuring system that will work in a wide variety of climates, without the need for desiccants and with minimal routine maintenance. When combined with the PRM2103-FF the integrated heater eliminates the need for desiccants and the remote calibration check minimizes routine maintenance.
By using the EPS2116 with the Model 831 or SoundExpert LxT sound level meter, the built in correction filters allow for class 1 response in free field (0°), random (diffuse), or 90° fields. This is accomplished with a single microphone, Model 377B02, and a simple selection on the sound level meter.
