Hydrogen Detector - SMART 3G-D3

  • Explosion-proof enclosure for ATEX Zone 2 and Zone 22 (with dust adapter).
  • Stainless steel sensor head.
  • Catalytic pellistor sensing element with linear response up to 100 % LEL.
  • Fast response time for flammable gas detection.
  • 7-segment display for real-time concentration visualization.

Add to compare

The SMART 3G-D3 is a gas detector designed for industrial use, featuring a catalytic sensor and an explosion-proof enclosure suitable for ATEX Zone 2 and Zone 22 environments (with a dust adapter). It offers real-time concentration visualization via a 7-segment display, supports multiple gas detection options (methane, LPG, propane, butane, petrol vapours), and includes features like Hall effect sensors for non-intrusive calibration, a 4-20 mA output, and optional RS485 communication. It is SIL2 hardware and SIL3 software, ensuring high safety standards.

Use Cases

  • Industrial area, ATEX Zone 2 and Zone 22 (when equipped with dust adapter, optional)

Capabilities
