Sensitivity, Selectivity, with Peak Precision, and Shortest Response Time
Introducing the H2 IntelliSense Slim Hydrogen Sensor, powered by our patented Solid State Electrochemical Sensor Technology. It offers a wide sensing range from 1ppm to 10% H2 v/v, ensuring you can detect gas at any concentration. Our sensors are free from cross-sensitivity to other gases, guaranteeing precise detection. They boast an unbeatable response time, ranging from 0.5 to 2.5 seconds (T20 to T90), enabling rapid reactions to environmental changes.
Notably, our sensors remain undamaged even when exposed to 100% hydrogen concentration and 99% RH moisture.Our hydrogen sensor continuously monitors hydrogen concentration and responds to corrective actions throughout the entire lifecycle of a hazardous-level situation, from leak detection to remedial action.
Stay informed and take prompt risk-mitigating measures with our advanced tracking system.
Product Features:
The following product features make it a versatile and ideal solution for stationary 24/7 hydrogen area monitoring and safety applications.
- Extremely low concentration detection: Our sensor can detect even extremely low concentrations of Hydrogen starting at 1ppm.
- Exceptional specificity: No cross-sensitivity from other combustible and reducing gases, ensuring accurate detection of Hydrogen alone.
- Ultra-fast response time: T20 to T90 in just 0.5 to 2.5 seconds, enabling early exposure to diffused Hydrogen.
- Intrinsically safe and sleek design: At just 98mm x 64mm x 34mm, our sensor’s sensing membrane is less than 4cm away from ceiling height, ensuring early exposure to diffused hydrogen.
- Lightweight and durable: Weighing less than 350 grams, our sensor is 4-5X lighter and smaller than sensors requiring a flameproof method of electrical safety. It uses a Rugged IP 68 powder-coated Aluminium enclosure and can survive in tough environmental conditions.
- Wide range of operating conditions: Our sensor can operate under varying pressure conditions, from vacuum to 1.5 bar, and in high humidity environments.
- Smart and reliable: Even if the Hydrogen concentration crosses explosive limits, our sensor remains operational and can track subsisting hazardous levels.  Our sensors won’t sustain any damage even when exposed to 100% concentration of hydrogen.
- Flexible and customisable: We offer a choice of 5 standard operating ranges and resolution combinations to suit your specific Hydrogen sensing needs.
- Wide choice of Background gases: Detect hydrogen with high accuracy in a choice of background gases, including Air, Helium, Nitrogen, Argon, Oxygen, Hydrocarbons, and Vacuum.
- Hazardous Area Deployment: Our sensor can be deployed in Zone 1 Gas Group IIC Hazardous Area and converted into a multi-point sampling-based aspirated system or portable sensor.
- Communication Options: RS485 Modbus, CAN Bus, 4mA to 20 mA 2-wire current loop, 0V to 5V analog signal.
- Modular additions in Safe Area
- Low Power Consumption: Low power consumption operates on industry-standard 24VDC (±5%) power supply.
- Ease of Installation:Â Simple installation and on-field gas calibration process.
- Design Variations in development:
- Convert a fixed Hydrogen sensor into a multi-point sampling-based aspirated system.
- Convert a fixed Hydrogen sensor into a portable sensor.
