Gages

This collection features a broad range of high-precision instruments, primarily focused on differential pressure and flow. Key products include the industry-standard Magnehelic® series, the compact Minihelic® II, and specialized units like the Capsuhelic® for high internal pressure and the digital DigiMag® series.

The Series 2000 Magnehelic® is the most popular choice for measuring differential pressure in air and non-combustible gases. It is widely used for monitoring fan and blower pressures, filter resistance, air velocity, and furnace draft. Its frictionless movement ensures high accuracy even in very low-pressure ranges.

The Series 2-5000 Minihelic® II is designed for applications where space is limited. It offers the same reliable diaphragm-actuated performance as the larger gages but in a much smaller footprint, making it ideal for integration into medical equipment, environmental cabinets, and small industrial machinery.

The Series 4000 Capsuhelic® is designed to handle much higher internal pressures (up to 500 psig) while still measuring small differential pressure changes. Unlike the Magnehelic®, the Capsuhelic® can also be used with liquid media, making it suitable for monitoring pressure drops across water filters or heat exchangers.

Yes, the Series DM-1000 DigiMag® is a digital alternative to the analog Magnehelic®. it features a large LCD display that eliminates parallax errors and provides a more modern interface for monitoring differential pressure and flow in commercial and industrial buildings.

Even mechanical gages like the Magnehelic® can drift due to environmental factors or mechanical wear. HK Calibrations ensures that your gages provide accurate, traceable readings. Regular calibration is critical for maintaining HVAC efficiency, ensuring cleanroom compliance, and preventing equipment failure due to incorrect pressure readings.
