Industrial Draft Gauge, Range -100 to 500 mmWC – Accurate Low Pressure Measurement for Boilers, Furnaces & HVAC Systems
Japsin Instrumentation presents the Industrial Draft Gauge, Range -100 to 500 mmWC, a precision-engineered low pressure measuring instrument designed for accurate monitoring of negative and positive pressure in industrial systems. This draft gauge is specially developed for applications where standard pressure gauges cannot provide reliable readings at very low pressure ranges. It is ideal for measuring draft, suction, air flow pressure, furnace pressure, chimney pressure, and ventilation system pressure with excellent repeatability and dependable long-term performance.
Industries such as power plants, chemical processing units, pharmaceutical plants, HVAC installations, food processing plants, steel plants, and manufacturing facilities require accurate draft pressure monitoring to maintain process safety and energy efficiency. Our Industrial Draft Gauge helps operators maintain controlled combustion, balanced airflow, and stable system pressure, ensuring optimum operational efficiency.
Built with robust construction, easy readability, and high sensitivity, this gauge is an excellent solution for measuring low pressure in air and gas applications.
The Industrial Draft Gauge, Range -100 to 500 mmWC is specifically manufactured to measure low pressure or draft conditions that occur in boilers, furnaces, ducts, blowers, chimneys, ovens, and air handling systems. The measuring range includes both negative pressure (-100 mmWC) and positive pressure (+500 mmWC), making it highly versatile for applications where suction and pressure variations need to be monitored continuously.
Unlike ordinary gauges used for medium and high pressure, draft gauges use sensitive measuring elements such as capsule or diaphragm systems, allowing precise response to very small pressure changes.
This model is engineered for industrial reliability and is available in multiple dial sizes, connection types, and mounting configurations to suit varied installation requirements.

3. Easy-to-Read Dial
Large clear dial with bold markings enables quick pressure reading from a distance, improving operational convenience.
4. Rugged Construction
Manufactured with durable metal or stainless steel case options for long life in industrial environments.
5. Sensitive Measuring Element
Special capsule or diaphragm sensing system ensures precise movement and accurate indication even at low pressure.
6. Multiple Mounting Options
Available in bottom entry, back entry, or panel mounting styles for easy installation.
7. Corrosion Resistant Options
Available with stainless steel wetted parts for harsh and corrosive environments.
Applications
The Industrial Draft Gauge is widely used in numerous industries for low pressure and draft monitoring:
1. Boiler Systems
Maintains correct furnace draft pressure for efficient combustion and reduced fuel consumption.
2. Furnaces
Measures internal draft conditions to optimize burner performance and safe operation.
3. Chimneys & Exhaust Systems
Used to monitor chimney draft and flue gas flow performance.
4. HVAC Systems
Ideal for air handling units, ventilation ducts, filter pressure drop indication, and airflow balancing.
5. Clean Rooms
Monitors low differential pressures to maintain contamination control environments.
6. Ovens & Dryers
Ensures controlled airflow and proper chamber pressure.
7. Dust Collection Systems
Measures suction pressure and filter loading conditions.
8. Industrial Ventilation
Tracks air movement and pressure in duct systems.
Why Draft Pressure Monitoring Is Important
Low pressure systems often operate with very narrow pressure tolerances. Even small pressure changes can affect:
- Combustion efficiency
- Heat transfer performance
- Fuel consumption
- Product quality
- Air circulation
- Emission control
- Operator safety
By installing a reliable Industrial Draft Gauge, operators can immediately detect abnormal conditions such as blocked ducts, fan failure, excess draft, insufficient airflow, or pressure imbalance.
