DELTI-Vac REV (DVR) apparatus presents 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 DVR was developed for All-in-One testing of high explosives, propellants, rocket fuels, primary explosives and pyrotechnics. DVR provides safe VST measurements of the latest precision level.
A cluster of multiple devices substitutes the outdated concept of controlling unit with connected heating blocks or a master block with connected slave blocks.
