2000-300MM – High-Accuracy, Easy-to-Install Differential Pressure Gauge from Dwyer

1. Introduction to the Dwyer 2000-300MM Differential Pressure Gauge

The 2000-300MM is a mechanical differential pressure gauge from Dwyer Instruments (USA), part of the well-known Magnehelic® series. It is designed to measure pressure differences between two points in a system and is widely used in HVAC systems, cleanrooms, pharmaceutical plants, fume hoods, and more.

With a measuring range of 0–300 mmH₂O, this model is ideal for low-pressure applications requiring high sensitivity and fast, accurate response.

3. Real-World Applications of the 2000-300MM Differential Pressure Gauge

The 2000-300MM is commonly used in systems that require accurate and continuous pressure monitoring:

Cleanrooms and pharmaceutical plants: Monitors pressure differences between clean zones to ensure GMP compliance.

Fume hoods and air showers: Ensures filters are operating efficiently to protect user health.

HVAC systems (AHU – FCU): Measures pressure drop across air filters to monitor performance and issue alerts when filters need replacement.

Laboratories and hospitals: Maintains proper airflow direction using positive or negative pressure zones.

Industrial facilities: Measures pressure in compressed air systems, suction lines, and mechanical rooms.

4. Advantages of the Dwyer 2000-300MM Gauge

High accuracy

With a margin of error of only ±2%, the device delivers stable and reliable readings even in mildly vibrating environments.

Mechanical design, no power supply needed

Operates based on Dwyer’s Magnehelic® magnetic force principle, requiring no electrical power – cost-effective and easy to use.

Flexible installation

Compact size; can be mounted directly on a control panel or wall. Standard 1/8” NPT ports make it easy to connect to pressure tubing.

Easy to read and operate

Large, clear display with smooth, responsive needle. Optional accessories available: mounting bracket, silicone tubing, contact alarm module.

Durable and corrosion-resistant

Epoxy-coated aluminum casing resists oxidation and harsh environments, ensuring long-term use.

5. Installation Guide for the 2000-300MM Differential Pressure Gauge

Proper installation is key to stable and long-lasting operation:

Step 1: Select installation location

Avoid places with excessive vibration or extreme heat.

Can be wall-mounted or installed on a control panel (using Dwyer standard mounting kits).

Step 2: Connect pressure tubing

HIGH (+) port: Connect to the higher-pressure side.

LOW (–) port: Connect to the lower-pressure side.

Use flexible pressure tubing. Avoid sharp bends or clogs.

Step 3: Check for leaks

Ensure there are no leaks at connection points.

Use heat-resistant sealing tape on threads to improve airtightness.
