I'm struggling with a device which measures specific gravity,

connects to my LAN and supposedly sends the data collected to a website,
maybe every 15mins. There are a few such sites I can use for this, but
I'm struggling to get any of them working, or confirm the data is being
sent to them.

My two routers log connected devices, but the device showing up in the
lists are quite rare, because it only connects for a couple of seconds.
How can I be sure the device is managing to connect, how can I check if
it is trying to relay the data?

Is this a commercial beast or some Arduino thing you've built etc from a
design?

If the latter, I'd be surprised if there isn't a facility, while a PC is
connected and running the Arduino IDE, to run the 'terminal'utility
which monitors activity. Generally, those who write SW, will, for
example, 'print' to the terminal:

Connecting to Wifi
Connected to Wifi
Sending data
Data sent

etc

It may be worth looking at the design notes and checking.
