UltraRAE is a quick spot-check monitor, typically used by occupational health, safety and environmental personnel. The combination filter tube and PID removes the disadvantages associated with colorimetric tubes and gas chromatographs.

Interchangeable RAE-Sep Filter Tubes

  • Benzene
  • Methylene Chloride (Halocarbon)
  • Butadiene (Polymer manufacture)

Key Features

  • The only compound-specific monitor with combination of interchangeable separation tubes and PID
  • 3 to10 times faster analysis vs. conventional tube or portable gas chromatograph methods
    • Results obtained in seconds (<75 seconds) rather than minutes
    • Detects benzene down to 0.1 ppm in 60 seconds
  • 3,000 - point datalogging storage capacity for data download to PC compatible with Windows 98, NT, 2000 and XP
  • Excellent range and linearity
    • Good down to 0.1 ppm and up to over 200 ppm benzene (no more GC column overload problems)
    • More accurate than gas detection tubes
  • Internal pump
    • Allows you to sample deep (up to 30ft or 10m) into a confined space
    • Prevents liquid flow into the monitor
    • Warns if sample tubing is blocked or crimped
  • Low cost of ownership
    • Inexpensive analysis due to low-cost RAE-SepTM tubes vs. gas detection tubes
    • Cheaper than portable GC, and no annual factory calibration
  • Large keys operable with 3 layers of gloves
  • Large easy-to-read backlight display
    • Alarm activated
    • Darkness or manually activated
  • Optional vibration alarm
  • Snap-in rechargeable or alkaline battery pack, 10 hours of operation with smart battery charging


  • 7.75"L x 2.75"W x 1.5"H (19.7 x 7.0 x 3.8 cm)


  • 16 oz with battery pack (455g)


  • Photoionization detector with vacuum UV lamp
