High-Accuracy Capsule Pressure Gauge for Low Pressure Measurement Applications
The “Ji” Japsin Instrumentation Capsule Pressure Gauge is a precision-engineered instrument specifically designed for measuring very low positive pressures with exceptional accuracy and reliability. Featuring a 4-inch (100 mm) dial size, pressure range of 0 to 5000 mmWC, dual scale indication of 0 to 500 mBar, direct mounting bottom entry, 3/8″ BSP (M) process connection, stainless steel case, stainless steel wetted parts, and a micro adjustable pointer, this gauge is ideal for applications where accurate low-pressure monitoring is critical for process performance and safety.
Unlike conventional pressure gauges that are primarily used for medium and high-pressure applications, capsule pressure gauges utilize a highly sensitive capsule element capable of detecting extremely small pressure changes. This makes them the preferred choice for HVAC systems, clean rooms, ventilation systems, air handling units, dust collection systems, filtration plants, pharmaceutical facilities, laboratories, and various industrial process applications requiring precise low-pressure measurement.
Built with durable stainless steel construction and advanced sensing technology, the “Ji” Japsin Instrumentation Capsule Pressure Gauge provides long-term performance, dependable operation, and excellent measurement stability in demanding industrial environments.
Designed for Accurate Low Pressure Measurement
Many industrial processes require precise monitoring of low-pressure air and gas systems. Standard bourdon tube pressure gauges may not provide sufficient sensitivity for these applications, resulting in reduced accuracy and limited measurement resolution.
The “Ji” Japsin Instrumentation Capsule Pressure Gauge is specifically engineered to overcome these limitations. The highly responsive capsule sensing element detects even minor pressure variations and converts them into accurate mechanical movement displayed on the dial.
This specialized design allows operators to monitor low-pressure conditions with confidence, ensuring efficient process control and reliable system performance.
Pressure Range: 0 to 5000 mmWC
The gauge is calibrated for a measuring range of:
Primary Scale
- 0 to 5000 mmWC (Millimeters Water Column)
Secondary Scale
- 0 to 500 mBar
This range is widely used in industrial low-pressure applications where pressure monitoring is required in air, gas, and ventilation systems.
The measurement range is suitable for:
- Air handling units
- Ventilation systems
- Clean rooms
- HVAC equipment
- Dust collection systems
- Industrial filters
- Furnace draft measurement
- Combustion air systems
- Laboratory testing equipment
- Process control applications
The broad low-pressure range enables the gauge to provide accurate readings while maintaining excellent sensitivity throughout the measuring span.
Dual Scale Display for Easy Monitoring
The instrument features a clearly marked dual-scale dial that displays pressure in both mmWC and mBar.
Benefits of Dual Scale Reading
- Eliminates manual pressure conversions
- Improves operator convenience
- Suitable for international applications
- Enhances process monitoring efficiency
- Reduces reading errors
Operators can instantly interpret readings in their preferred engineering unit, making the gauge suitable for a wide range of industries and technical environments.
Precision Capsule Element Technology
The core measuring component of this instrument is a highly sensitive metallic capsule element.
The capsule consists of specially formed diaphragms joined together to create a sealed chamber. As pressure is applied, the capsule expands proportionally and transfers movement through a precision linkage mechanism to the pointer.
Advantages of Capsule Technology
- High sensitivity to low pressures
- Excellent measurement accuracy
- Stable long-term performance
- Superior repeatability
- Reliable pressure indication
- Fast response to pressure changes
This technology makes the gauge particularly suitable for applications where low-pressure monitoring is essential.
Micro Adjustable Pointer for Enhanced Accuracy
One of the key features of this model is the Micro Adjustable Pointer.
Benefits of Micro Adjustable Pointer
- Precise zero setting

The adjustable pointer allows technicians to perform fine calibration adjustments when necessary, helping maintain measurement accuracy throughout the instrument’s service life.
This feature is especially valuable in quality-critical environments such as pharmaceutical manufacturing, laboratories, and calibration facilities.
Large 4-Inch Dial for Superior Visibility
The gauge features a large 100 mm (4-inch) dial, providing excellent readability in industrial environments.
Advantages
- Easy viewing from a distance
- Reduced operator fatigue
- Faster process monitoring
- Improved safety
- Better operational efficiency
The large dial size ensures that pressure readings can be easily observed during routine inspections and system monitoring.
