Dilatometer
Dilatometry – expansion measurement – DIL
Within the realm of precision instrumentation, Linseis stands as a vanguard, crafting an extensive array of dilatometers. These encompass single, double, differential, quattro, quench, deformation, laser, and optical variants. The temperature spectrum these marvels traverse is nothing short of astonishing, spanning from a frosty -263°C to a searing 2800°C.
What sets Linseis apart is its unwavering commitment to precision. Our dilatometers are endowed with the capability to autonomously measure the alterations in length, be it in solids, powdered pastes, or even the fluid elegance of liquids.
Crucially, our products adhere rigorously to international standards, ensuring their reliability and compatibility with established benchmarks. These standards include the likes of ASTM E831, ASTM D696, ISO 11358, ISO/DIS 9924, ASTM E1131, ASTM D3850, ASTM D6375, ASTM D6370, ASTM E2550, and ASTM D3175. Linseis, thus, empowers industries and researchers with the tools to explore the nuanced dimensions of materials, forging paths into the realm of precision and compliance.

Relative Humidity L40/RH
- The typical temperature range for a humidity generator is between room temperature and 80°C with a controllable relative humidity from 0.2% up to 98%
- For the analysis of food, pharmaceuticals, building materials, or biological processes
- The other possibility is to measure under isothermal conditions
Water Vapor L40/MV
- By mixing water vapor, produced in a water vapor generator, with a carrier gas like air, nitrogen, or helium, variable concentrations (in Vol.-%, wt.% or ppm) of the water vapor in the sample gas can be adjusted within our analyzers.
- The generator evaporates water without necessarily mixing the residual water vapor with other purge gases, which allows a 100% H2O atmosphere at the sample.
