G201005 VOCpro UL/ATEX Certified Hand-Held PID Monitor by Casella

The Casella VOCpro uses proven photo-ionization technology for detecting volatile organic compounds (VOC’s). It has a 10.6 eV lamp as standard, with an optional 11.3 eV version for ionizing chlorinated compounds. The UV lamp is easy to maintain and keep clean. The TWA, STEL and Average values are displayed on a large display and the integral pump provides a rapid sampling response. An audible alarm feature is available to warn the user that the current instantaneous level or the STEL or TWA levels have been exceeded.

Key Benefits

  • 10.6 eV lamp as standard
  • optional 11.3 eV lamp
  • easy to use even with gloves
  • range 0.1 to 2,000 ppm
  • extended range up to 20,000 with optional dilution probe
  • intrinsically safe for use in hazardous areas
  • memory for up to 15,000 data logging points
  • menu driven operation with just 3 large buttons
  • dedicated calibration control key
  • wide range of accessories
  • backlight for use in low light areas
  • 3 stage alarm for peak, STEL and TWA values with buzzer

Applications

  • Health and safety monitoring
  • OSHA and NIOSH compliance
  • Ambient air monitoring
  • Source appointment
  • Boundary and fence line monitoring
  • Forensic investigations
  • Contaminated land surveys
  • Emergency and incident response
  • Anesthetic gas surveys
  • Chemical storage and transportation surveys

The non logging mode is the simplest mode of operation and when selected it will show the total concentration level that is being detected by the Casella VOCpro unit.

The tag mode allows the user to make measurements of the background concentration level plus the sample separately and to “tag” the readings with a site code for ease of identification later. Results may be datalogged during this mode of operation.

The interval mode displays the TWA, STEL, Average and current readings on the display with results logged to memory at a user selectable interval. The instant reading is updated every second while the STEL is updated at 1 minute intervals and shows the last 15 minutes average value on screen. The TWA is continuously updated and normalizes the total accumulated concentration to the standard 8 hour exposure duration.

Operation and use

Simply switch on the Casella VOCpro and the unit will power up to the last used operating mode ready to go. The pump can be temporarily turned off to save power when not needed for a measurement and the lamp will be switched off too to prevent it from being damaged.

The span of the VOCpro can be checked by introducing a sample gas of known concentration to calibrate the unit. Normally a gas such as isobutylene is used since the unit responds with medium sensitivity to it and it is therefore a good indicator of the total ionizable compounds present.

The Casella VOCpro pc software package G202034 and cable G202028 is available to download the stored values to a computer. Once downloaded these data results can be printed, archived or exported to a spreadsheet for further manipulation or calculations.
