Application software

The modular application concept brings various additional functions and applications, allowing you to configure your sound level meter from an ever-growing library of application modules. 

Types 2270, 2250, 2250-L and 2238 can host application modules, which can be ordered factory-installed, or added later as your measurement requirements expand. Additional application modules are easy to download and can coexist on the instrument in any combination, and are maintained constantly to ensure they always comply with the latest international standards.
