Tiger XT Select

Benzene PID gas detector with two operation modes!

The Tiger XT Select is a portable benzene PID gas detector with two operation modes for rapid detection of benzene gas and Total Aromatic Compounds (TACs) providing accurate, reliable data.

The Tiger XT Select portable benzene PID gas detector is capable of providing 15-minute short-term exposure limits (STELs) and 8-hour time-weighted averages (TWAs) for total aromatic compounds (TACs).

The Tiger XT Select portable benzene PID gas detector, displays real-time data, ensuring the final reading represents the full value of actual benzene gas present. Benzene gas concentrations are displayed down to parts-per-billion (ppb) levels, giving you accurate, reliable data you can count on.

The Tiger XT Select can also be used in ‘standard Tiger operational mode‘ without the use of a benzene pre-filter tube to deliver active indications of volatile organic compounds (VOCs), including benzene, at concentrations as low as 1 ppb benzene equivalent.

This gas detector has a thermo plastic elastomer outer moulding, this rubber material is semi-conductive making the Tiger XT Select intrinsically safe.

Key Features

  • Improved robust design can withstand harsh environments
  • Large internal gas table with over 750 VOCs & toxic compounds
  • IP65 ingress protection against a range of weather conditions
  • <2 second response time, one of the fastest and most accurate on the market
  • Instantaneous alarms, RED & AMBER with loud 95 dBA sounder
  • Humidity resistant and
    anti-contamination design
    ensures optimal performance

Typical Applications

  • Confined Space Entry
  • Plant Maintenance
  • Marine Down-Stream Monitoring
  • Hazardous Material Response
  • TAC Detection at Loading Docks and Barge Operations
