You gotta build a HUD chip from the blueprint first. Then it’ll display the temperature directly on your HUD while you're exploring!
Just combine it with the HUD chip, and you'll see the temperature while diving. No need for a separate device!
You honestly don’t need it. I’ve played through twice without ever crafting one.
