Stiko’s Advanced Differential Pressure Recorders
Beyond meters, Stiko also offers differential pressure recorders that provide continuous, visual pressure trends, perfect for field applications. These recorders come in durable Pelicases and support ranges from 600 mbar up to 25 bar, making them ideal for critical monitoring.
Deadweight Testers Stiko
Deadweight tester
A deadweight tester is a precise calibration tool used to accurately calibrate pressure measuring instruments. By utilizing the principle of pressure balance, deadweight testers apply known pressures through calibrated weights, providing a reliable and cost-effective solution for pressure calibration. This method ensures high accuracy across a wide range of pressure testing applications, making it ideal for industries that require consistent and precise pressure measurements.
Why Stiko Deadweight Testers Are the Benchmark for High-Accuracy Pressure Calibration
When it comes to precise pressure calibration, professionals worldwide rely on deadweight testers for their unmatched accuracy and reliability. Among the top choices in the industry are the Stiko deadweight testers, known for their robust construction, superior materials, and certified precision.
In this article, we explore the key advantages of Stiko deadweight testers and explain why they are ideal for critical pressure measurement tasks.
1. Unmatched Accuracy with Tungsten Carbide Pistons
At the heart of every Stiko deadweight tester is a piston-cylinder assembly made of ultra-hard tungsten carbide. This material is chosen for its:
Extremely low coefficient of friction
Superior wear resistance
Exceptional dimensional stability under pressure
The result? High-accuracy pressure readings over a long lifespan. For models with 0.01% and 0.008% accuracy (DOS001 and DOS0008), cylinder deformation remains below 2·10⁻⁶ /MPa, ensuring consistent performance even in demanding applications.
2. Certified Calibration Data for Reliable Results
Every Stiko tester is delivered with a detailed calibration certificate, providing:
Effective area at zero pressure and 20°C
Thermal expansion coefficient
List of individual weights and their mass values
Deformation factor (lambda) for precise correction
Other compensation factors affecting pressure calculation
With this data, users can apply a high-accuracy pressure formula, accounting for all variables to achieve traceable and repeatable results.
3. Robust Stainless Steel Construction
Stiko testers are engineered for stability and longevity:
A solid stainless steel base plate can be securely bolted to a workbench.
The triangular stainless steel chassis can be independently levelled with adjustable feet.
An integrated spirit level ensures perfect horizontal alignment, critical for precision.
This design supports accurate and stable operation, even in busy calibration labs or industrial environments.
4. Innovative Free-Hanging Weight Carrier Design
For ultra-precise models (DOS001 and DOS0008), a free-hanging weight carrier is used. This unique design ensures:
Perfect vertical alignment of the weights and piston
Automatic compensation for tilt, reducing alignment errors
Zero friction operation, improving measurement consistency
Unlike other systems, no motorized drive is required thanks to Stiko’s precise machining and excellent free-turning capability.
5. High-Quality Materials and Calibrated Weights
Stiko uses only non-magnetic stainless steel for all weights, and stainless steel for all wetted and structural parts. Only a few moving components are made from low-friction bronze and brass.
Each weight is:
Individually calibrated
Documented in the calibration certificate
Tared using a precision chamber, which can also be reused during recalibration
Within 10% uncertainty margin of the total tester accuracy
This ensures consistently accurate pressure output, even over years of use.
6. Fast and Easy Operation
Efficiency matters. That’s why every Stiko tester includes:
A quick connector for easy, tool-free connection to the device under test
A large-volume hand pump, eliminating the need for a separate priming pump and enabling fast pressure generation
These features make pressure testing and calibration quick, clean, and efficient—ideal for high-throughput labs or field calibration work.
Conclusion: Invest in Accuracy and Longevity with Stiko
If your work demands high-accuracy pressure calibration, Stiko deadweight testers deliver the performance, durability, and traceability required in today’s demanding environments.
With their tungsten carbide pistons, precision-calibrated weights, and certified performance, Stiko testers are the go-to solution for professionals who can’t afford to compromise on measurement quality.
