High-purity specialty gas delivery and distribution systems: Semiconductor manufacturing processes-ranging from etching and ion implantation to thin-film deposition-rely on specialty gases that are ultra-high purity or even highly toxic.
With wetted parts made of 316L stainless steel and a low surface roughness (Ra ≤ 0.15 μm), the HNP60 effectively prevents particle adsorption and contaminant outgassing, ensuring gas purity during delivery and distribution-a factor directly linked to product yield.
Its helium leak test specification (<1e-10 mbar·L/s) also meets the rigorous sealing requirements of such systems.

Chemical supply systems (particularly for wet processes): Wet processes such as wafer cleaning and etching utilize large quantities of high-purity, corrosive chemical liquids.
The sensor's all-stainless-steel construction and corrosion-resistant materials ensure compatibility with these specialized media, maintaining reliable stability and measurement accuracy even during prolonged exposure to chemical liquids.

On-tool gas panels and flow control:
Semiconductor front-end manufacturing equipment-such as etchers and deposition systems-incorporates complex gas delivery and distribution piping.
The HNP60's compact size and flexible electrical connection options (e.g., M12 aviation connectors) make it ideal for integration into space-constrained panels, enabling real-time monitoring of gas pressure at critical points and providing accurate feedback for process control.

First, consider the materials and cleanliness. It features an all-316L stainless steel construction with wetted surface roughness (Ra) controlled below 0.15 μm. This specification is critical for ultrapure media systems, as it directly minimizes particle adhesion and process fluid residue, thereby substantially impacting yields in semiconductor and photovoltaic manufacturing processes. It achieves a leak rate of <1e-10 mbar·L/s and undergoes a 48-hour full-scale pressure retention test, demonstrating rigorous pre-shipment leak control.

Next is the stability of its accuracy. The 0.25% FS accuracy rating encompasses nonlinearity, hysteresis, and repeatability; rather than merely citing linearity under ideal conditions, it represents a comprehensive error figure, offering greater practical value. With annual stability better than 0.25% FS and thermal drift controlled at 0.3% FS/10°C (across the -10 to +55°C range), the device does not require frequent removal for recalibration in environments with fluctuating shop-floor temperatures-a feature field engineers will certainly appreciate.

Finally, there is the ease of field use. It supports zero-point and full-scale adjustments, with "one-touch zeroing" models available; this allows for on-site correction of zero-point offsets caused by static pressure or mounting position differences, eliminating the need to return the unit to the factory. Output signal options include 4–20 mA, 0–10 V, and discrete (switch) outputs, while connection options include M12 aviation connectors and direct cable outlets. This flexibility allows it to meet the requirements of various PLCs and control systems.

Overall, this product does not rely on a single standout parameter but instead offers a balanced performance across cleanliness, long-term reliability, and field adaptability, making it well-suited for high-value production lines where downtime and contamination risks are critical concerns.
