Option 1 - Free debugging of local machines
You can use the Safari browser for Windows ( download Safari 5.1.7 ).
Steps
- Turn on the Development menu in the menu bar (press the Alt key to open the menu bar, then go to the Edit menu> Preferences> Advanced tab). Find this option below.)
- Then follow through the menu "Development"> "User Agent". Choose iPad, iPhone, etc.
The Development menu (for example, Show Web Inspector) has more options to help debug your site, etc.

Option 2 - Paid, browser access for the target browser / OS / machine
I personally used http://www.browserstack.com/ , and it allows you to test functionality in a wide combination. However, debugging may not be as convenient as on the local machine.
There may be more companies providing similar services.
Beware of basic online emulators
As mentioned in the commentary , be careful with emulator websites. Example: the website I came across claimed to emulate an iPhone with an iPhone image, and iframe was inside it, being obediently represented by the browser, I opened this website in (Firefox).
