DELTI-Vac MIL and DELTI-Vac MIL+ (DVM) devices present a cost-effective and modern solution for R&D and quality assurance laboratories across the branch. Efficient metal heating block, LCD touch screen interface, precise digital vacuum sensors and gas-tight tubes are combined into standalone apparatus which can be connected to PC for online data streaming, evaluation and remote operation. The DVM was developed for safe and precise VST measurements of high explosives, propellants, rocket fuels and pyrotechnics. It follows most of the major VST stability testing standards.
A cluster of multiple devices substitutes the outdated concept of controlling unit with connected heating blocks or a master block with connected slave block
