Accurate pressure measurement is essential in every industrial environment. From refineries and power plants to research laboratories and aerospace units, industries rely on precise pressure readings to maintain safety, quality, and efficient operations. Among all pressure calibration tools, the dead weight pressure gauge remains the most trusted and accurate primary pressure standard.
For decades, Nagman Instruments has been recognized as a leading manufacturer of precision calibration equipment, offering world-class solutions that support industries with reliable performance and long-term accuracy. Their dead weight pressure gauges are engineered to deliver maximum stability, repeatability, and traceability—making them an indispensable tool for calibration laboratories and industrial test facilities.
In this blog, we explore why dead weight pressure gauges are considered the gold standard, how Nagman Instruments maintains its leadership in the calibration industry, and how their instruments integrate with modern tools like precision pressure controllers, calibration software, and black body calibrators to provide complete calibration solutions.
What Is a Dead Weight Pressure Gauge?
A dead weight pressure gauge, also known as a dead weight tester, is a primary standard used for calibrating pressure instruments. The principle is simple but highly accurate:
Pressure is applied to a piston–cylinder system, and calibrated weights are placed on the piston to balance the applied pressure. This generates a reference pressure that is extremely stable and precise.
Dead weight testers are widely used because they:
-
Provide traceable, primary standard accuracy
-
Require no electronics or power
-
Ensure long-term stability
-
Deliver highly repeatable results
Even with modern digital instruments available, dead weight testers remain the most reliable method for pressure calibration worldwide.

How Nagman Combines Traditional Accuracy with Modern Technology
While dead weight testers remain the primary standard, industries today require faster workflows, digital integration, and automated measurement. Nagman Instruments meets these needs by offering complementary technologies that work seamlessly with dead weight testers.
1. Precision Pressure Controllers – Automation for Pressure Calibration
A precision pressure controller automates pressure generation and regulation. Instead of manually pumping pressure, the controller uses closed-loop digital control for stable and repeatable test points.
Why They Are Used with Dead Weight Testers
-
The controller generates the pressure.
-
The dead weight gauge provides the reference.
-
The device under test is compared against this standard.
This combination speeds up calibration while maintaining accuracy.
Nagman manufactures precision pressure controllers that deliver:
-
Ultra-stable pressure
-
Fast control response
-
High-resolution readings
-
Automatic test sequences
When used together, the pressure controller and dead weight tester create a powerful calibration ecosystem.
2. Calibration Software – Digital Accuracy, Zero Manual Error
Modern industries prefer paperless, automated calibration systems. Nagman’s calibration software integrates with their instruments to:
-
Automate calibration routines
-
Log real-time data
-
Compare readings
-
Generate calibration certificates
-
Maintain traceability
-
Monitor trends and performance
Using software with a dead weight pressure gauge brings multiple benefits:
-
No handwriting errors
-
Faster documentation
-
Standardized certificates
-
Better audit compliance
This combination improves efficiency and ensures calibration results are consistent and trustworthy.
3. Black Body Calibrators – Supporting Temperature Calibration Needs
While pressure calibration is essential, industries also require highly precise temperature calibration. Nagman’s black body calibrator is used for calibrating infrared thermometers, thermal imagers, and pyrometers.
Even though temperature and pressure calibration are separate domains, many laboratories need both systems.
Nagman offers:
-
Pressure calibration instruments (dead weight testers, pressure controllers)
-
Temperature calibration instruments (dry blocks, black body calibrators)
-
Multifunction electrical calibrators
-
Calibration benches and accessories
This makes them a complete calibration equipment provider.
