Sensitivity, Selectivity, and with Peak Precision, and Shortest Response Time

H2 IntelliSense Slim Hydrogen Sensor is powered by patented Solid State Electrochemical Sensor Technology. With sensing range options from 1ppm to 10% H2 v/v, you'll have the flexibility to detect gas at any concentration. Plus, our sensors have no cross-sensitivity to other combustible and reducing gases, so you can be sure you're only detecting the gas you're interested in. Our response time is unbeatable, with T20 to T90 in just 0.5 to 2.5 seconds so you can react quickly to any environmental changes. And best of all, our sensors won't sustain any damage even when exposed to 100% concentration of hydrogen.

Our hydrogen sensor tracks the changing hydrogen concentration in response to corrective actions, covering the entire lifecycle of a hazardous-level leak, accumulation, and remedial action. This method ensures you are always aware of the situation and can take the appropriate steps to take the risk.

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 customizable: We offer a choice of 6 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, Methane, Hydrocarbons, and Vacuum.
  • Hazardous Area Deployment: Oursensor 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.
