Differential Pressure Meters

A differential pressure meter is a specialized instrument designed to measure the difference in pressure between two distinct points within a system. This is crucial for applications such as monitoring air filters in HVAC systems, measuring gas flow rates, or checking for pressure drops across industrial machinery to ensure optimal performance and safety.

The current collection features three high-performance models from Testo: the compact Testo 510 for quick daily measurements, the Testo 526-1 industrial pressure meter, and the Testo 526-2, which is designed for high-precision differential pressure monitoring. Each model is tailored to meet different levels of accuracy and environmental demands.

The Testo 510 is highly valued for its portability and ease of use. It is a pocket-sized differential pressure meter that allows for rapid measurements of gas flow pressure and manifold pressure. Despite its small size, it is temperature-compensated to ensure that readings remain accurate regardless of changing environmental conditions on the job site.

The Testo 526 series (including the 526-1 and 526-2 models) is built for more complex industrial environments. These meters offer high accuracy and the ability to log data for long-term analysis. They are particularly effective for checking the tightness of pipelines or monitoring sensitive pressure changes in automated production processes where precision is paramount.

Yes, the precision offered by models like the Testo 526-2 makes them excellent tools for leak testing. By monitoring the differential pressure over a set period, technicians can detect even minute pressure drops that indicate a leak in a sealed system or pipeline, helping to prevent costly waste or safety hazards.

HK Calibrations provides professional calibration services for all differential pressure meters in this collection. Regular calibration at one of our Australian laboratories ensures that your instrument continues to provide measurements that are traceable to national standards, which is essential for maintaining quality control and meeting regulatory compliance.
