NA41 Set Noise Sensor Outdoor Wind & Rain Cover

The NA41 is a protective device designed specifically for outdoor noise sensors, offering protection against wind, rain, and birds. It consists of a main body and a windproof cover. The main body has two parts:

The upper part features angled protrusions that securely hold the windproof cover and channel water outward, preventing it from entering the sensor.
The lower part fits perfectly with the noise sensor, ensuring reliable protection.

IP65 Protection Rating

The NA41 outdoor protective device meets the IP65 protection standard, featuring a 70mm windproof ball and seamless waterproof mesh for comprehensive microphone protection. This design ensures effective dust and waterproof capabilities. In outdoor noise measurements, sensitive microphones and equipment are exposed to diverse weather conditions like rain, wind, and snow. The NA41 device is designed to withstand such harsh elements, safeguarding equipment and data against adverse weather effects effectively.

Noise Monitor Protection in Any Weather.

Completely prevent dust from entering.

No impact from rainwater falling at any angle.

Easy Calibration

The NA41 outdoor protective device consists of a main body component and a windproof cover. The main body is divided into upper and lower sections, with the upper section featuring evenly spaced protrusions at a specific angle to secure the windproof cover. This design effectively directs water away to protect the microphone from moisture ingress. The lower section is intricately designed to accommodate the microphone. Both sections are fastened with threads, facilitating easy manual disassembly for microphone calibration.

Precisely concise structure.

Removable top section for easy microphone calibration.

Wind-resistant And Noise-reducing

The equipment provides effective wind noise reduction and excellent wind resistance. In an environment with a wind speed of 10 meters per second, the combination of the NA41 windproof cover and device structure can provide over 30dB of wind noise reduction. Furthermore, the equipment as a whole can operate normally without damage in an environment with a wind speed of 30 meters per second.
