In this study, information is given about the driers commonly used in the industry and the experimental errors and uncertainties that will be encountered in the experiments using these driers are tried to be explained by using the data obtained from the experiments carried out in an 8 chambers hot oil heated stenter, which is a conveyor type convection dryer. The fabric used in the experiments is the Thessaloniki type fabric, containing 67% cotton and 37% polyester. The experiments were carried out at a drying air temperature of 160 ºC and a fabric advance rate of 23 m/h (0.383 m/s). Thus, the example of error analysis in such experimental studies is provided and criteria that may cause an error for drying systems are discussed. As a result of the uncertainty analysis, the largest uncertainty in the system occurred in temperature measurements at ±0.367 - ±0.568 ºC values and the error rate for the whole system was found to be 4.08%. In terms of conducting the experiments in real production conditions and the materials and methods used in the experiments, this study is thought to will be help researchers that working on drying systems in their experimental studies.
