Intelligent wide range composite vacuum gauge 0.01Pa --100kPa 0.25 level linear dual displaydetailed description:

VR-208C-310Series intelligent vacuum gaugeis a kind ofA new type of vacuum gauge with intelligent measurement and control function, which is a precision digital display adjustment of vacuum degreemeter,suitforIndustrial automation precision measurement and control of various vacuum equipment, such as biomedicineVacuum freeze-drying, pharmaceuticals, and fine chemicals、Vacuum acquisition equipmentVacuum unitMulti stage vacuum unit, vacuum drying, vacuumfilter、Vacuum smelting, vacuum forging heat treatment, vacuum single crystal furnace, optoelectronic industry, aerospace and military industryVacuum equipment, chemical vacuum distillation, etc, measuring range 0.003-200kPa~2MPa, 0.25/0.5 level).

VR208-310The series of intelligent vacuum instruments adopts the new foreign technologyFirst generation ceramic pressure barrierVacuum measurementTechnology（high precisionCeramic absolute pressure vacuumruleofVacuum sensor,By integrating the research achievements of intelligent instrument technology, the shortcomings of traditional vacuum gauges such as large measurement errors, poor linearity, and narrow effective measurement range have been overcome;Measurement of vacuum degreePerformanceStabilityRange width, reliabilitysafetyAll have shown significant improvement；

developedIntelligent wide range composite vacuum gauge 0.01Pa --100kPa 0.25 level linear dual display typeBy using imported composite vacuum gauge components and combining them with precision data processing of intelligent instruments, the performance has been further improved. Its range has been extended to 0.01Pa~100kPa (4/5-digit significant digital display, non power type), with excellent precision and linearity throughout the entire range. Therefore, it can accurately measure and precisely set the vacuum degree at any point within the full range, which is the same as the wide range vacuum gauge with traditional power type display.

In addition, this series of products has strong industrial protection performance, and its vacuum sensors can choose protection levels: IP57~IP67, explosion-proof vacuum gauges with dust-proof, rainproof, and explosion-proof (explosion-proof level ExiaICT6) performance, and corrosion-resistant vacuum gauges made of 316L stainless steel (- F3) or polytetrafluoroethylene (- F4) and ceramic sensor chips. Especially suitable for vacuum measurement and control, automation instrument devices in industries such as chemical, pharmaceutical, petroleum, new materials, and new processes with harsh environments.
