Wire type for low water sensor in 200' well

[Paltus]

what is a good type of wire to use for low water sensor ? The sensor I got is 2 leads that (apparently) short in the water and the wire length there is 15 feet or so. I need closer to 200'. what type of wire should I use.

thanks

PS I promised pipe thread VS glue adapter experiment results in a different thread,
will post them when I get them. soon.
