I'm working on controlling an incubator by writing commands to its serial port, a 9 pin RS232. The commands are simple byte strings, such as #02ts. The incubator responses are similar to the commands I send. If I connect it to my computer with an RS232 to USB cable, everything works great.

Now I'm looking to control it remotely, and I was told to try a serial to wifi adapter. I've come across a vast variety of items which claim to do this, and I'm lost when it comes to what each item is suited for, and I have no idea what exactly it is I need. What is the best way to wirelessly communicate to this incubator's serial port?

Look at ESP8266 based modules. They are very cheap and functional. And doing exactly what you need.

Lots of relevant links here

And just a text search produces a useful amount.
