What is a Compound Gauge?
A compound gauge is a specialized measuring instrument capable of indicating both vacuum and positive pressure on the same dial. Unlike standard pressure gauges that measure only positive pressure, compound gauges allow operators to monitor systems that operate below and above atmospheric pressure.
This capability is particularly important in applications such as:
- Vacuum pumps
- Air handling systems
- Filtration equipment
- Suction lines
- Process vessels
- Packaging machinery
- Pneumatic equipment
- Laboratory systems
The “Ji” Japsin Instrumentation Industrial Compound Gauge enables seamless monitoring of pressure transitions, helping operators maintain optimal process conditions.
Pressure Range: -1 to 1.6 Kg/Cm²
This compound gauge is calibrated to measure:
Vacuum Range
- -1 Kg/Cm²
Positive Pressure Range
- 0 to 1.6 Kg/Cm²
The range is specifically selected for low-pressure industrial applications where accurate monitoring of slight pressure and vacuum variations is required.
Applications involving blowers, ventilation systems, filter monitoring, vacuum chambers, and process control systems benefit significantly from this measurement range.
Dual Scale Display for Easy Interpretation
The gauge incorporates a clearly marked dual-scale dial.
Primary Scale
- -1 to 1.6 Kg/Cm²
Secondary Scale
- -30 InHg to 22.5 PSI
This dual-unit configuration allows operators to quickly interpret readings without performing manual conversions.
Advantages of Dual Scale Reading
- Easy operation
- Improved productivity
- Reduced operator error
- Faster process monitoring
- International compatibility
The large and well-defined markings ensure excellent visibility in industrial environments.
High Accuracy – ±1% FSD
Precision measurement is essential in process industries where even small pressure deviations can affect product quality and system performance.
The “Ji” Japsin Instrumentation Compound Gauge provides an impressive ±1% Full Scale Deflection (FSD) accuracy.
Benefits of High Accuracy
- Improved process control
- Better equipment protection
- Enhanced operational safety
- Consistent measurement performance
- Reliable system diagnostics

Accurate readings help identify abnormal operating conditions before they become major issues.
Glycerin Filled for Stable Performance
The gauge is filled with high-quality glycerin to provide superior damping and vibration resistance.
Industrial equipment often generates vibration and pressure pulsations that can cause the pointer of a dry gauge to fluctuate excessively. Glycerin filling eliminates this problem by stabilizing pointer movement.
Benefits of Glycerin Filling
- Reduced needle vibration
- Improved readability
- Enhanced measurement stability
- Protection of internal components
- Longer instrument lifespan
- Better performance in harsh environments
This feature makes the gauge particularly suitable for compressors, pumps, blowers, and industrial machinery.
Large 4-Inch Dial for Superior Visibility
The instrument features a 100 mm (4-inch) dial, providing excellent readability from a distance.
Advantages of Large Dial Size
- Easy monitoring
- Improved operator convenience
- Reduced reading errors
- Better process visibility
- Suitable for plant installations
The large display enables operators to quickly verify process conditions during routine inspections and operations.

This model is supplied with a surface mounting arrangement, making it ideal for control panels, equipment enclosures, and centralized monitoring stations.
Benefits of Surface Mounting
- Easy installation
- Secure positioning
- Improved accessibility
- Professional appearance
- Convenient monitoring
Surface mounting is commonly used where operators need direct visual access to pressure readings.
Bottom Entry Design
The gauge utilizes a bottom entry process connection, providing a practical and widely accepted installation method.
Advantages
- Simplified installation
- Better dial orientation
- Secure mounting
- Reduced piping complexity
- Industrial standard configuration
Bottom entry gauges are commonly installed in process plants and machinery systems.
