NanoSentry
Nano + Chronia
Sensor hardware and control software, engineered together so every data point is precise, fast and actionable.
Nano — the sensor
Selective and sensitive
Detects molecular-level changes without cross-gas false positives.
Field-proven
Stable performance across varying humidity and temperature.
10x longer lifespan
No consumables or periodic replacements: lower total cost of ownership.
Chronia — the control
Real time, 24/7
Continuous monitoring with closed-loop control, 10x faster.
Predictive analytics
Triangulates a leak’s origin and anticipates maintenance needs.
Traceable data
Full history ready for audits and compliance reporting.
01 · Sensing
MOS and functionalized graphene sensors
At the heart of NanoSentry are metal-oxide semiconductor (MOS) sensors and graphene functionalized with specific receptors. When a gas molecule touches the surface, it triggers a minimal but measurable physical change in the material.
02 · Processing
Proprietary control, precision and stability
A control process patented by NanoChronia stabilizes the sensor reading and filters environmental noise, ensuring response speed and precision even in demanding industrial environments.
03 · Monitoring
Real-time IoT dashboard
Data streams to a dashboard accessible from anywhere, with instant leak alerts and historical traceability for audits and compliance reporting.
Roadmap
Where NanoSentry is heading
We keep miniaturizing the hardware, widening gas specificity, improving detection sensitivity and lowering power consumption — so denser sensor networks can be deployed at a lower cost.

NanoSentry
Gases we detect today
Each sensor is calibrated and validated for a target gas, with alert thresholds configurable to your regulatory or internal policy.
Hydrogen gas
Hydrogen
Key to the energy transition, but highly flammable and colorless. Early detection is critical in production, transport and storage.
Greenhouse gases
Methane
With a warming potential far higher than CO2 in the short term, methane leaks are one of the energy industry's top regulatory targets.
Toxic gases
Hydrogen sulfide
Extremely toxic even at low concentrations. Early detection directly protects the lives of on-site workers.
Toxic gases
Ammonia
Widely used in industrial refrigeration and agriculture. Corrosive and dangerous at high concentrations, requiring constant monitoring.
