A digital differential pressure manometer is an electronic instrument used to measure the difference in pressure between two points. It converts pressure signals into digital readings, providing high accuracy and easy readability. This device is commonly used in HVAC systems, cleanrooms, laboratories, and industrial processes to monitor airflow, filter conditions, and system performance. Compared with analog manometers, digital models offer faster response, multiple measurement units, and clearer display.
Digital Display & Clear Buttons
- Clear and Easy-to-read Display. The LCD screen provides a clear and easy-to-read display of pressure values. And this manometer with backlighting for use in low-light environments (backlight button on the side of the device).
- Ease of Operation. Clear, well-labeled buttons make the manometer simple to operate. This reduces operation errors and increases efficiency, especially in fast-paced environments.
- Multiple Measurement Units. This differential pressure manometer supports multiple units such as kPa, mbar, psi, inH₂O, inHg and so on. Users can switch units instantly.
Lightweight Differential Manometer
- Reduced User Fatigue. Lightweight differential manometer minimizes hand and arm strain during extended measurements. When tasks require repeated readings or prolonged holding, a lighter instrument helps improve operator comfort and productivity, reducing the risk of fatigue-related errors.
- Enhanced Portability and Field Use. Lightweight construction supports compact and handheld design, making the manometer suitable for quick diagnostics and spot checks. This flexibility is valuable in maintenance work where fast response and convenience are critical.
Applications
SISCO's differential pressure manometer is widely used in HVAC systems to monitor air flow, filter condition, and room pressure balance. In industrial processes, it helps measure pressure drops across valves, pumps, and pipelines to ensure efficient operation. It is commonly applied in cleanrooms and laboratories to maintain controlled environments. In the energy and chemical industries, differential pressure manometers are used for flow measurement and leak detection.

Q1: What is the a digital differential pressure manometer?
A1: A digital differential pressure manometer is an electronic device used to measure the difference in pressure between two points in a system. It provides accurate, real-time readings on a digital display, often with features like unit conversion. Commonly used in HVAC systems, cleanrooms, laboratories, and industrial processes, it helps monitor airflow, filter performance, or system efficiency. Unlike traditional analog manometers, it offers higher precision, ease of use, and quick measurement without manual interpretation.
Q2: What factors should be considered when choosing a differential pressure manometer?
A2: When choosing a differential pressure manometer, several key factors should be considered. First, measurement range—ensure it covers the expected pressure differences. Accuracy and resolution are critical for reliable readings. Response time matters for dynamic applications. Consider the units and display type (digital or analog) for ease of reading. Portability and size may be important for field use.
Q3: How does temperature affect the accuracy of the digital differential pressure manometer readings?
A3: The accuracy of a digital differential pressure meter can be affected by several factors. Temperature fluctuations can alter sensor readings, while humidity and condensation may interfere with electronics. Improper installation, such as misaligned tubing or leaks, can cause measurement errors. Vibration and mechanical shocks can destabilize the sensor.
Tips: What units of measurement does this digital differential pressure manometer support?
This digital differential pressure manometer supports multiple units of measurement, making it versatile for various applications. It can switch between 11 different units: inH2O, psi, mbar, kPa, inHg, mmHg, Ozin2, ftH2O, cmH2O, kgcm2, bar. This flexibility enables precise monitoring and comparison across different systems, whether for HVAC, laboratory, or industrial applications, ensuring accurate readings in the unit most suitable for the task.
