VACUUBRAND VACUU•VIEW extended Digital Vacuum Gauge

Overview

The VACUUBRAND VACUU•VIEW extended is a digitally integrated, dual-sensor vacuum gauge engineered for reliable and chemically resilient pressure monitoring across the rough to medium vacuum range (0.001–1100 mbar). It combines two complementary sensing technologies in a single compact housing: a piezoresistive ceramic diaphragm sensor for high-accuracy absolute pressure measurement at higher pressures (≥1 mbar), and a ceramic-sheathed Pirani sensor optimized for thermal conductivity-based detection in the lower mid-vacuum region (down to 0.001 mbar). This hybrid architecture eliminates the need for separate gauges when transitioning between atmospheric conditions and deep rough vacuum—enabling seamless process oversight in applications such as vacuum drying, solvent removal, freeze-drying pre-evacuation, vacuum distillation, and glovebox inert gas purging. Its all-ceramic sensor construction ensures long-term stability and resistance to aggressive vapors—including halogenated solvents, acids, and organic condensates—common in pharmaceutical, chemical synthesis, and materials research environments.

Key Features

• Integrated dual-sensor design: ceramic diaphragm + ceramic-sheathed Pirani sensor for continuous coverage from ambient to 10⁻³ mbar
• Chemically inert sensor elements and housing—resistant to corrosion from HCl, HF, acetone, chloroform, and other aggressive media
• Bright, high-contrast LCD with intuitive menu-driven interface; supports mbar, torr, hPa, and psi units
• Rugged, lightweight polymer enclosure rated IP54 for dust and splash resistance
• Factory-calibrated with optional DAkkS-accredited calibration certificates (traceable to national standards)
• Plug-and-play operation: includes DN 6/10 mm hose barb fitting, wall-mount power adapter, and mounting hardware
• Compliant with NRTL safety requirements for North America and ATEX Directive 2014/34/EU (Category II 3G, Group IIC, Temperature Class T4, for internal atmosphere only)

Sample Compatibility & Compliance

The VACUU•VIEW extended is compatible with non-condensable gases and low-vapor-pressure process media typical in laboratory and pilot-scale vacuum systems. Its ceramic sensor surfaces prevent adsorption-induced drift during repeated exposure to polar or reactive species. The device meets ISO/IEC 17025-aligned calibration practices when used with DAkkS-certified services (e.g., part no. 900214 or 900215). For regulated environments—including GLP and GMP-compliant labs—the gauge supports audit-ready documentation through its stable zero-point behavior and repeatable full-scale response. While not intrinsically safe for explosive external atmospheres, its ATEX marking confirms suitability for use inside sealed enclosures where hazardous gas ingress is prevented.

Software & Data Management

The VACUU•VIEW extended operates autonomously without software dependency; however, analog output (0–10 V or 4–20 mA) is available via optional interface modules for integration into SCADA or PLC-based process control systems. All displayed values are stored in non-volatile memory and retain calibration history across power cycles. Though it does not feature USB or Ethernet connectivity, its digital display includes real-time min/max tracking and configurable alarm thresholds—supporting basic data logging via external chart recorders or analog input DAQ systems. For traceability in regulated workflows, users may pair the gauge with VACUUBRAND’s certified calibration reports, which include uncertainty budgets compliant with EA-4/02 and ISO/IEC 17025:2017.

Applications

• Process vacuum monitoring in rotary evaporators, vacuum ovens, and lyophilizers
• Leak testing and evacuation verification in analytical instrument sample chambers (e.g., SEM, XRD, TGA)
• Quality control of vacuum packaging integrity in food and medical device manufacturing
• Gas purge validation in inert-atmosphere gloveboxes and Schlenk lines
• Educational lab demonstrations of gas laws and vacuum physics principles
• Environmental simulation chambers requiring stable rough-to-medium vacuum feedback

FAQ

What vacuum ranges does the VACUU•VIEW extended cover, and how is accuracy distributed across that range?
It measures continuously from 0.001 to 1100 mbar. Accuracy is ±15% of reading between 0.01–5 mbar, and ±3 mbar above 5 mbar. This reflects the inherent limitations of thermal conductivity sensors at higher pressures and the diaphragm sensor’s optimal zone at mid-to-high vacuum.
Can this gauge be used with corrosive vapors such as hydrochloric acid or trifluoroacetic acid?
Yes—the ceramic diaphragm and ceramic-sheathed Pirani sensor elements, along with the chemically resistant polymer housing, provide proven resistance to common corrosive volatiles encountered in synthetic chemistry and etching processes.
Is the device suitable for permanent installation in a vacuum system?
Yes. It features a robust IP54-rated enclosure, fixed mounting options, and continuous-duty rating up to 40 °C media temperature. For intermittent high-temp exposure (e.g., during bake-out), short-term tolerance extends to 80 °C.
Does it comply with FDA 21 CFR Part 11 or EU Annex 11 requirements?
As a standalone display instrument without electronic signature or audit trail functionality, it does not meet Part 11 or Annex 11 directly—but it supports compliance when integrated into validated systems using external data acquisition platforms with appropriate ALCOA+ governance.
What calibration documentation is available?
Standard shipment includes factory calibration. Optional DAkkS-accredited certificates (part nos. 900214 and 900215) provide metrological traceability to PTB (Physikalisch-Technische Bundesanstalt) standards, including expanded uncertainty statements and environmental correction factors.
