You could use microbial swabs instead of data logger , by these swabs you will be able to determine exactly the No. of microorganisms.

Yes, do it by a manual procedure.
Hand held thermometer to check core temperatures of random finished goods at exit of oven
Dear rusong,
I think we are talking about heat treatment in a belt oven? There are some temperature indicators on the market (e.g. from testo) but with all other types of equiment you have to determined the correct "holding time at °C". Just measuring the temperature is not sufficient. In a belt oven you can read the temperature probe at several "windows"/checks.
