ProCeas® H2 purity analyzer

ProCeas® H2 purity analyzer

Product catalog summary

Overview: The ProCeas® H2 Purity system is designed for multi-gas, trace-level analysis to ensure hydrogen purity and quality control. It complies with ISO 14687:2025 and ISO 19880 standards, suitable for both online and offline analysis, and is available in pressurized enclosures for ATEX, IECEx, and cUL compliance.

Key Features and Benefits:

Utilizes patented OFCEAS® and LPS® technologies for ultra-accurate, real-time measurements.
Can be combined with GC/FID-TCD for full ISO14687 compliance, validated through the MetroHyVe project.
Offers high selectivity without cross-interference and does not require zero gas or carrier gases, reducing operational complexity.
Provides a wide, dynamic measuring range and long-lasting accuracy without the need for re-calibration or sensor replacement.
Reduces operational costs and complexity with multi-point measurement and low maintenance requirements.
Enables fast decision-making with real-time, accurate data for process control and gas quality assurance.
