Optical Dilatometer

Optonom OD- 201 model optical dilatometer has been developed as a result of long Research and Development activities to meet the needs of glass, ceramic, metal, plastic industries, universities, test and research centers.

Dilatometre Dilatometre

High-resolution image sensor by an optical system to analyze in real time the desired sample analysis can be performed. Therefore, video images can be monitored in real time as well as photo image.


The biggest advantage compared to traditional mechanical push-rod dilatometers, is to provide the opportunity to measure directly without any physical contact with the sample.


Because of the influence of the sample thrust in push-rod mechanical dilatometer made with high margin of error of linear expansion measurements. Fewer errors can be made with OD-201 optical dilatometer through as physical non- contact. Due to horizontal design, thin film sample measurements can be easily accomplished that cannot be carried out in conventional push-rod mechanical dilatometers. .


Optonom OD-201 model thermal processing providing the connection of particles at high temperatures occurring in the samples can be observed through the optical dilatometer briefly sintering.


The process of compacting and forming a solid mass of material by heat and/or pressure without melting it to the point of liquefaction can be measured by Optonom OD-201 optical dilatometer.
