Why Acrylic U Tube Manometers Are Still the Gold Standard?

Despite the emergence of digital differential pressure gauges, U-tube manometers continue to remain the preferred choice in many industries. Their reliability lies in physics-based measurement using manometric fluid—eliminating the need for batteries, electronics, or calibration drift.

Benefits include:

• 100% mechanical measurement with no electronic components

• Zero drift even in long-term usage

• Highly repeatable readings

• No calibration required under normal conditions

• Simple installation and operation

• Extremely cost-effective

• Ideal for low-pressure ranges where digital sensors often struggle

The 200-0-200 mmWC range is widely used in HVAC, filter monitoring, lab research, and airflow measurements.

High-Quality Acrylic Body for Perfect Readability:

The manometer is manufactured using premium-grade acrylic, offering:

• Crystal clear transparency

• High scratch resistance

• Strong structural integrity

• Excellent chemical resistance

• Fade-proof visual clarity

The precision-machined acrylic block ensures smooth internal surfaces and perfect vertical alignment, essential for accurate differential pressure readings.

The scale is engraved or laser printed, preventing peeling, fading, or distortion even after years of industrial use.
