• Built-in converting capabilities
  The converting capabilities are built into the small, lightweight and compact detector unit.
• Key and display function
  The detector unit has operation keys and digital display function and can be used by the unit itself. In addition, the calibration and the creation of calibration curves at site are easy.
• Measurement with high-speed and high sensitivity
  By high-performance CPU and improved optical components, high speed (output renewal cycle: 28ms) and high sensitive measurement can be performed.
• Setting display unit
  The setting display unit has a front panel of 96 x 96 mm and can connect with up to 9 sets of the detector unit. The communications interface between the setting display unit and the detector unit is by RS-485.
• Protective structure conforming to IP-65
  The enclosure of the detector unit and the front panel of the setting display unit conform to IP-65 for severe atmospheric condition.
• CE
  Models complying with CE are available.
• Explosion-proof construction
  Models complying with [ExdIIBT4] is available.
