    FAQ

    • Will this sensor be fine in a saltwater?

      May I know how many sensors do you need? If the quantity is large, we will consider it .

    • Is this probe safe for prolonged exposure to wine, or do you have another product that will meet my requirements?

      I want to continuously monitor the wine temperature over a period of time.

      Yeah, it could stay in the wine for a long time, but I am afraid some organic matter will make a chemical reaction with the probe. It is better add a safe and health isolating course between the probe and wine. Don't make a directly contact.
