Insplorion NPS-P2
Next-Gen hydrogen detector for low-oxygen environments
Atex ready – Approval pending
Insplorion NPS-P2 is a ground-breaking hydrogen detector. Its nanoplasmonic sensor element reacts quickly and selectively to hydrogen also in the absence of oxygen. Designed to enable the development of new and existing hydrogen applications
Works without oxygen
Unlike most hydrogen sensors, you can install Insplorion NPS-P2 in low-oxygen spaces, such as pipe-in-pipe systems or nitrogen-purged enclosures. This saves on costs of sampling and ventilation systems.
Effective in complex gas environments
Exceptional hydrogen specificity ensures reliable performance. Reacting only to hydrogen minimizes the risk of false alarms and costly disruptions.
Extremely quick response
With a t90 response time of under 5 seconds, Insplorion NPS-P2 enables immediate action. Ideal for safety-focused operations where every second counts.
Minimal maintenance
The solid-state, optical sensor has no consumables, no moving parts, and requires minimal maintenance. That means fewer interruptions and decreased long-term costs.
Safe and compact
A compact design and flexible configurations make it ideal for confined spaces. Insplorion NPS-P2 is ATEX ready and will be certified for zone 1 in Q3 2025.
0–4% hydrogen
Insplorion NPS-P2 is a detector with a accuracy of
< 0.2 vol% . It can be exposed to hydrogen concentrations up to 100% without damage.
Suitable for use in:
- Hydrogen storage systems – Monitor leaks and ensure containment.
- Compressor rooms – Fast and reliable detection in high-risk zones.
- Fuel cell enclosures – Compact design fits inside tight enclosures.
- Ventilation exhaust – Early warning where hydrogen may accumulate.
- Pipe-in-pipe solutions – Detect leaks directly inside confined tubing.
Improve your hydrogen detection with world-first technology
Insplorion NPS-P2 features the world’s first palladium-based nano sensing technology in optical form. Built for long-term performance in inert environments – it delivers rapid and precise hydrogen detection without relying on oxygen or consumable parts.
How Insplorion NPS-P2 compares to other sensor technologies
Configurations
The detector can be configured for measurements in gas in the ambient through diffusion, or via forced flow through the detector. A third variant features an internal M20 thread for attachment to an adapter.
