Johnson Controls G-2010-11 Pressure Gauge

The Johnson Controls G-2010-11 Pressure Gauge is a professional-grade diagnostic and monitoring tool designed specifically for pneumatic control systems. This high-precision air pressure gage features a 2-inch dial face with a dual-scale readout, providing clear measurements from 0-30 psig and 0-200 kPa. Engineered for stem mounting, it utilizes a standard 1/8" NPT center back connection for secure integration into control panels or direct line placement. As the direct replacement for 2420-003, this unit ensures seamless compatibility for field repairs and system upgrades. The G-2010-11 is built with a black lacquer finish and high-contrast white face to maintain readability in low-light mechanical rooms, while the removable acrylic lens allows for easy cleaning and recalibration access in the field.

• Dual-Scale Precision: Displays both 0-30 PSI and 0-200 kPa with an accuracy rating of 3-2-3% per ANSI B40.1M standards.
• Direct Cross-Reference: Engineered as the official replacement for 2420-003, ensuring HVAC pneumatic systems maintain original design specifications.
• Industrial Durability: Features a robust phosphor bronze Bourdon tube and brass socket for reliable performance in HVACR environments.
• Wide Temperature Range: Rated for ambient operation between -20°F and 150°F (-29°C to 66°C), suitable for varied mechanical room conditions.
• High-Visibility Interface: Blue metric scale and black imperial markings on a 2" face provide instant pressure verification for pneumatic air gauges.

Is the G-2010-11 compatible with existing 1/8" NPT fittings?
Yes, this 0-30 PSI gauge uses a standard 1/8" NPT center back connection, making it a universal fit for most pneumatic terminal units and controller modules.

Can this gauge be used for liquid media?
This specific model is calibrated and designed primarily for air media within pneumatic control systems. For oil or water applications, verify your system compatibility with brass and phosphor bronze wetted parts.

Does this replace the older 2420-003 model?
Correct. The G-2010-11 is the manufacturer-specified direct replacement, maintaining the same physical 2-inch footprint and stem mounting configuration.
