Precision in Every Drop: The Dwyer Mark II 25 Liquid Filled Wall Mount Manometer

The Mark II 25 is a low-range, liquid-filled manometer designed for wall mounting. It’s ideal for monitoring differential pressure in clean air applications—think HVAC systems, laboratory airflow, and filter performance.

Key Specifications:

• Range: 0–3 inches of water column (w.c.)

• Accuracy: ±3% of full scale

• Fluid: Red gauge oil for clear visibility

• Mounting: Wall-mounted with built-in leveling

• Scale: Easy-to-read white background with black markings

Whether you're balancing airflow in a cleanroom or verifying pressure drop across filters, the Mark II 25 offers:

• Visual Simplicity: No batteries, no screens—just a clear analog readout.

• Durability: Resistant to vibration and minor shocks thanks to its liquid damping.

• Ease of Installation: Comes with mounting hardware and leveling tools.

Applications That Benefit

This manometer is a favorite across industries:

• HVAC technicians use it to verify system performance.

• Cleanroom engineers rely on it for pressure monitoring.

• Environmental labs trust it for airflow validation.

A Tool That Speaks Your Language

The Mark II 25 is refreshingly analog. It doesn’t beep or blink. it simply tells the truth, drop by drop. For those who value tactile precision and visual clarity, it’s more than a tool—it’s a quiet partner in the pursuit of balance.
