Can I dip the temperature sensor in water?

I used mine with the sensor immersed for about a year. This was in a water bath in a crockpot for inexpensive sous vide cooking. I also used it for making yogurt. It failed after about a year and in my reading on the issue, this sort of failure is common if the sensors are immersed for long periods. I recently got a replacement unit and I will be protecting the sensor by using it with a thermowell, which is a close-fitting metal tube that is immersed in the liquid and sealed at one end, but open to the air at the other.

Is this device UL certified?

Hello, this device is not UL certified.

How long is the probe cord?

I believe the picture shows it is 118 inches.

Specs say the most power it handles is 2a inductive, nowhere near enough for a freezer or basically any ac. have many of us used it for that anyway?

I don't know what inductive load is. I use it on an infrared lighting fixture in a greenhouse that pulls about 15 amps without problem. The specs also list it as ok for refrigerators and freezers.
