I am looking to build a device that will let me test the temperature of products inside a fridge and freezer.
Can anyone recommend good temperature sensors for this? I know I can buy an infrared thermometer and save the hassle but this will be the start function of a multi tool proof of concept I am desining , the sensor needs to be accurate, +/- 1 degree Celsius. It also has to be able to deal with liquid if it's a touch based sensor.

You plan to actually stick probes into those products? An IR sensor would read only the surface temperature of a product, which may be quite different from the bulk of the product.
Anyway, the easiest is to use wired sensors, and just lead the wires through a hole in the door or the side of the fridge.
Hi,
Will the sensor be coming in contact with food?
If so you will need food grade sensors, specifically designed for the food industry.
I think you will find some health regs about it.
