Experience unparalleled accuracy and real-time control with the DHPG-222. Engineered for high-performance industrial and laboratory vacuum systems.
The DHPG-222 Advantage
In precision vacuum engineering, real-time data is the difference between success and system failure. The DHPG-222 Dual Display Digital Pirani Gauge is a flagship model designed for operators who demand instant visibility.
Unlike standard gauges, the DHPG-222 features a specialized dual-interface, allowing you to monitor both your current vacuum levels and your preset control points simultaneously. No more toggling menus—just pure, actionable data.
Key Features & Benefits
Dual Digital Display: High-visibility LED screens provide simultaneous readings of vacuum pressure and set-point parameters.
Wide Measurement Range: Optimized for the medium-to-fine vacuum spectrum, ensuring versatility across various applications.
Rapid Response Sensor: Integrated Pirani filament technology detects minute pressure fluctuations in milliseconds.
Dual Set-Point Relays: Easily automate your system by triggering external pumps or valves at specific vacuum levels.
Robust Industrial Build: Housed in a durable, interference-shielded casing to withstand harsh factory environments.
Applications & Use Cases
The DHPG-222 is the preferred choice for industries requiring stable and repeatable vacuum measurements, including:
Vacuum Coating & Metallizing: Precise control for thin-film deposition.
Freeze Drying: Reliable monitoring for pharmaceutical and food processing.
HVAC & Refrigeration: High-accuracy leak testing and system evacuation.
Research & Development: Perfect for physics labs and material science testing.
Transformer Oil Purification: Ensures deep vacuum levels for moisture removal.
Expert Installation Tip
Pro Tip: To maximize the lifespan of your DHPG-222 sensor, always install the gauge head in a vertical position. This prevents heavy particles or oil backstreaming from contaminating the Pirani filament, ensuring your calibration stays accurate for longer.
Frequently Asked Questions
1. Is the DHPG-222 compatible with different sensor heads? The DHPG-222 is optimized for our high-sensitivity Pirani sensors. However, it can be calibrated to work with most standard Pirani-type sensor heads available in the market.
2. Can I use this gauge for automated system shut-down? Absolutely. The dual set-point relays allow you to program the gauge to automatically shut down or start equipment when specific vacuum thresholds are reached.
