SD/LD-450

Features

  • Setup layout is flexible.
    The separated structure of oxygen sensor and thin converter greatly relaxed the limit of installation location.
  • Space saving
    New developed thin wall mounting type converter resolved the concerns about depth.
  • Super high speed response
    The shortest response can be achieved by separated sensor.
  • High durable sensor
    The sensor with special coating realized high durability.
  • Compliant standard
    Compliant with CE marking, EN61010-1, EN61326-1, and RoHS
  • Sensors are compatible with vacuum NW flanges (16, 25, 40) and screw-in units (3/8R).
