Looking for a high quality temperature probe with alarm

Once upon a time, I bought this (now junk) temperature alarm for my saltwater tank: https://a.co/d/6huxSzh

The problem is that the probe rusted on me. One of the big features I liked about it though was the alarm.

Does anyone have any good recommendations for a saltwater fish tank temperature probe with an alarm?

I'm debating if I spend a lot of money and buy probes and a reader from Ubibot.
