When it comes to noise monitoring, Svantek have a wide range of top-level equipment, from the smallest class 1 sound level meter, from the SV 971A, to the advanced sound level meter that is the SV 977, to the sleek and reliable SV 307A. However, in Autumn of 2024, a new noise monitoring station was released: The SV 303.
This meter changes the game of noise monitoring as you now have more choice in how you want to conduct your projects. The SV 307, or the SV 303? In this blog we’ll compare the SV 303 vs SV 307A, delving into their differences, helping you decide which one is best for you.
The SV 303: Compact and Cost-Effective
The SV 303, the new kid on the block, was designed with urban environments and smart city applications in mind.
The lightweight and compact design make it easy to deploy across many locations, perfect for large-scale noise assessment projects.
The device is also incredibly cost effective, meaning you can purchase many monitors to deploy in smart city monitoring, creating a mesh grid of noise monitoring across an area, giving you full data on a large area where 1 or 2 monitors wouldn’t cut it.
So, what are the key features of the SV 303?
- Smart City Ready: Integrates seamlessly with urban monitoring infrastructures, including vibration monitoring with the SV 803.
- Class 1 Compliance: Meets IEC 61672-1:2013 and IEC 61260-1:2014 standards for accuracy.
- Wide Measurement Range: Covers 30 dBA to 130 dBA RMS, suitable for diverse urban soundscapes.
- Environmental Resilience: Operates in temperatures from -20°C to 60°C and up to 95% humidity.
- Affordable Deployment: A cost-effective choice for multipoint monitoring.
This meter is best for short term noise studies, smart city applications requiring integration with other sensors and budget conscious projects that still require class 1 accuracy.
The SV 307A: Robust and Comprehensive
The SV 307A is one of the best-selling noise monitors in recent times, and that’s at no surprise, with its sleek and modern design, paired with its weatherproof case and incredibly reliable measurements.
This is built for longer term, to permanent installations and demanding conditions, making it the go-to choice for projects requiring long-term reliability. With advanced features like automated system checks and data streaming, it’s ideal for continuous monitoring.
That’s not to mention the power you get when pairing the meter with SvanNET, offering a host of features, also displaying data from your noise, vibration and dust monitoring, keeping all your data in one, easy to access place.
Key Features of the SV 307A:
- Patented MEMS Microphone: Offers lifetime warranty and dual system checks for accurate, reliable measurements.
- Advanced Connectivity: Includes a 4G modem for real-time data transmission and remote access via SvanNET.
- Extended Battery Life: Operates up to five days on a single charge with modem enabled.
- All-in-One Hardware: Combines noise, meteorological, and dust monitoring capabilities.
- High Durability: Withstands harsh environmental conditions, including extreme temperatures and high humidity.
