摘要

The probe (1) which has a control handle grip is a slender pointed (6) needle which can be inserted through the cardboard or plastic package containing the perishable products. The probe contains temperature sensors (2, 3), a humidity sensor (4) and possibly other sensors for gas concentration, etc. Data from the probe is recorded by a computer system for analysis of the effects of transport conditions on product shelf life.
