Non-contact optical thermal expansion gauge "ODP 868"

Optical thermal expansion measuring instrument for demanding research and development and manufacturing technology labs.

The "ODP 868," a result of over 20 years of research and development on optical testing devices for analyzing the thermomechanical behavior of materials, enables sample analysis that surpasses the limitations of conventional heating microscopes. With its multifunctionality, the ODP 868 is a highly innovative tool suitable for optimizing industrial processes related to manufacturing, research and development, and thermal cycles. The heating microscope mode uses a 5Mpix high-resolution camera to analyze the physical behavior of materials during industrial firing cycles. Through practical morphometrics, it calculates and visualizes various characteristic temperatures and parameters selected by the user in real-time during analysis. The ODP 868 can analyze samples of a wide range of shapes and sizes (for example, measuring 3mm and 10mm samples simultaneously) and can analyze up to 8 ISO standard-sized samples at the same time.

basic information

The horizontal dilatometer mode with two HiRes video cameras allows for the analysis of the expansion and contraction of samples with lengths ranging from 30 to 60 mm. It can track up to 50% contraction at a maximum heating rate of 100°C/min. For melting samples, there are disposable fixing plates available. The entire measurement system is temperature-controlled and insulated from the furnace chamber. The vertical dilatometer mode uses two HiRes video cameras to analyze the expansion and contraction of samples less than 20 mm placed vertically in the furnace chamber. It can track the firing process of materials that show up to 100% contraction at a maximum heating rate of 100°C/min. The development of the glassy layer does not interfere with the test results because the upper part of the sample can move freely even if the lower base is in contact with the sample fixing plate. In the absolute bending measurement mode, three cameras can simultaneously measure the sample position at three different points (patented by TA), eliminating the need for correction curves. Bending experiments can be measured with samples of lengths 80-85 mm or 25-30 mm.
