Unattended Noise Monitoring

A tailored solution for outdoor noise monitoring is available for the XL2 Sound Level
Meter. The outdoor measurement microphone M2230-WP and the heavy-duty outdoor
case ideally complement the XL2 system for unattended noise monitoring.

Outdoor Microphone
M2230-WP is a weather-protected microphone solution for the XL2 Sound Level Meter
allowing acquisition of environmental noise data in outdoor applications. The corrosion-
free polymer housing, wind screen and water-repellent membrane protect the micro-
phone capsule. The outdoor microphone M2230-WP fulfills IEC 61672 Class 1 as well
as the ANSI S1.4 Type 1 requirements. The upper section of the weather protection kit
is snap-on mounted and can thus be easily removed by hand for convenient and quick
calibration of the measurement microphone.

Outdoor Case
The outdoor case delivers a professional solution for unattended noise monitoring.
It protects the XL2 Sound Level Meter from severe weather conditions and offers
generous space for batteries and further accessories. The connection cable to the out-
door microphone runs into the case through a rain-protected aperture.

Smooth Setup of Pass/Fail Criteria

As soon as a new product goes into pro-
duction, the significance of the Pass/
Fail criteria must be considered. This ad-
justment represents a major challenge
because both the relevance of measure-
ments as well as the level of the yield
depends directly on optimizing these to-
