I think your dispatcher gives it to you. Unless you buy you a reefer trailer yourself, and ask for a manual for the trailer. That is what I think. But if you have another answer just post it if you can.
You actually find this thermometer, and you set the temperature to what your dispatcher tells you to set it on. But you can only set the temperatures with the reefer/refrigerated trailer.
I doubt it for just a purchase.

In trucking, a “reefer” is a refrigerated trailer that gets attached to a semi-truck in order to transport perishables and other temperature-sensitive goods. It was originally the ice cream industry that gave birth to the reefer around 1925. Reefers may also be used for heated goods.
A reefer trailer typically uses diesel fuel to power its refrigeration unit. This unit is responsible for maintaining the required temperature for perishable goods during transport. Some modern reefers may also utilize electric power from the truck or external sources when parked. Overall, diesel remains the primary fuel source for most reefer trailers.
You can find reefer at the Place where you do 'C' Cortez missions.You can also buy the boat yard and then use any of the boats there and capture any reefer from the sea from the other person.
There are reefer and refrigerated trailers made for the trucking and railroad industries. Check your local Trucking companies, and of course your local railroad. Penske usually has all kinds of new and used trailers, both reefer and refrigerated.
