Key features :

  • 0.01-5000ppm
  • Measures 480 selectable compounds
  • Humidity resistant functionality
  • Datalog 30 000 readings
  • Intrinsically safe; meets ATEX, IECEx, US and Canadian certification pending
  • 16 hours runs time
  • 2 years warranty


CubTAC is a personal VOC detector for the fast, accurate detection of total aromatic compounds (TACs), including benzene, keeping you safe within your working environment. Comfortable and unobtrusive to wear, CubTAC is the smallest, lightest, personal TAC and benzene detector available. CubTAC  has a dynamic range of 0 to 5000 parts per million (ppm), with its market leading ppb sensitivity, CubTAC comes with all the benefits of the Cub personal VOC detector but has a 10.0 eV lamp utilising a nique light filtering technology to give a reliable aromatic hydrocarbon concentration. 
When worker exposure exceeds pre-set limits Cub’s audible, vibrating and flashing LED alarms alert you to the gases present. Readings are displayed on its bright, back-lit LCD display with selectable data logging time.
CubTAC uses Ion Science patented PID sensor technology that has been independently verified as best performing for speed, accuracy, and humidity resistant operation. Its unique Anti-contamination design and patented Fence Electrode Technology provide extended run time in the most challenging environments, giving you accurate results you can truly rely on.

Standard kits include :
  • CubTAC instrument
  • Docking station
  • Remote calibration adaptor
  • Accessory kit
  • Stack removal tool
  • Mains cable
  • USB cable
  • Quick start guide
  • Calibration certificate

Tiger Select in action

Tiger Select - Benzene & Total Aromatic Compound (TAC) detection in one instrument


Key features :

  • 0-20 000ppm in TAC mode
  • 0 - 40 ppm or 130 mg/m3 benzene in tube mode
  • Humidity resistant functionality
  • Intrinsically sare : II 2G Ex ia IIC T4 (- 15 0C ≤Ta ≤+45 0C), ITS09 ATEX 26890X, IECEx ITS 10.0036X, US and Canadian approved
  • Datalog > 120 000 points
  • Optional TWA and STEL recording with preloaded regulatory standards per gas
  • 24 hours runs time
  • 2 years warranty and up to 5 years, when registering online 
The Tiger Select is revolutionary hand-held gas detector with two mode operation for the rapid detection of benzene and Total Aromatic Compounds (TACs) providing accurate, reliable data you can count on.Utilising the high output Ion Science 10.0eV detection system, a reading for Total Aromatic Compounds (TACs) is seen immediately on start-up. Should aromatics be detected, a Draeger benzene pre-filter tube can be easily attached to ensure rapid detection and selective measurement of benzene. Throughout the measurement process, Tiger Select continues to display real time data, ensuring the final reading represents the full value of actual benzene present. Benzene concentrations are displayed down to ppb levels, giving you the most accurate, reliable data you can count on. 
Tiger Select is capable of providing 15 minute STELs and 8 hour TWAs for TACs. A 10.6 eV lamp can easily be installed for the detection of a wide range of TVOCs. In addition, the unique MiniPID VOC sensor incorporates both Anti-contamination technology and Fence Electrode technology for extended operation in difficult working environments. The Tiger Select benzene and total aromatic compound detector can also be used in standard Tiger operational mode without the use of a benzene pre-filter tube to deliver active indications of VOCs, including benzene at concentrations as low as 1 ppb benzene equivalent. 
Standard kits include :
  • Tiger Select instrument
  • Rechargeable battery (Li-ion)
  • Battery charger and mains adaptor
  • Rubber boot
  • Explorer case
  • USB memory stick
  • Benzene pre-filter tubes
  • Tiger Select manual
  • Tiger Select Quick Start Guide
  • Benzene pre-filter tube opener
  • Carbon filter assembly
  • PTFE filter discs
  • Removable tool for MiniPID stack
  • Sample cleaning compound
  • Lanyard
  • Calibration adaptor
  • Sensor seal – coated
