Recommended way to check Google Analytics is running correctly on every page (wordpress)

I have a Wordpress site that has multiple plugins & that has somehow over time got the same Analytics tracking link (albeit slightly different implementations of it) in a few places on the site.

I want to remove one of them so the site 'touch wood' only uses a single tracking link throughout, is there a website scanning tool or desktop application that will scan an app and help me find each location of this tracking link?
