LPG Diffusion Type Fixed Gas Detector Head with Display SDE-KD-12B

Available on backorder

  • A diffusion type gas detection with concentration and alarm display function. Gas concentration and alarm status can be seen at a glance even at the work site, helping to ensure the safety of workers.
  • Detector output can be checked during maintenance and sensor calibration can be performed by just one person, leading to cost reduction.
  • KD-12 A /B /C are hydrogen and acetylene explosion-proof(Ex d IIC T5). KD-12 D /O /R are explosion-proof(Ex d IIB T5).
  • Magnetic stick adjustment makes maintenance easy.
  • KD-12 A/B/C are lead-free and compliant with the European RoHS Directive.
  • Waterproof and dustproof (protection class IP65).
  • JIS self-conformity declaration (KD-12O).
  • The KD-12B-SIL is the first domestic gas detector/ alarm to receive functional safety certification.
  • KD-12AH/KD-12BH supports HART communication. Advanced monitoring is possible with existing cables.
  • The KD-12HT directly detects high boiling point solvents in a drying oven. The sensor can be used in an environment of 160℃.
