TVOC 2 fixed PID Detector
For continuous VOC monitoring
TVOC 2 is a fixed continuous PID detector for the detection and measurement of total volatile organic compounds (TVOCs). Its photoionisation detection (PID) sensor capabilities utilise advanced patented Fence Electrode Technology with increased resistance to humidity and contamination.
A robust fixed PID detector, TVOC 2 has a selectable detection range of 0 – 10 ppm, 0 – 100 ppm or 0 – 1000 ppm and is ideal for use in manufacturing and process industries where VOCs are typically present.
With a 4-20 mA analogue output, TVOC 2 can be simply integrated into a Distributed Control System (DCS) to provide warnings and enable control of high VOC levels in the working environment.
The instrument’s ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas without safety barriers, whilst its ATEX and IECEx approvals allow TVOC 2 to be used in Zone 1 hazardous areas with safety barriers.
Simple to install service and calibrate, TVOC 2 requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.

FALCO fixed VOC detector
Designed with ‘typhoon technology’ for extreme weather and condensing atmospheres!
Falco is the latest generation of fixed VOC detectors that continuously detect a wide range of volatile organic compounds (VOCs) using patented photoionisation detection (PID) technology.
Unique to this fixed VOC detector is its revolutionary ‘typhoon technology’ safeguarding the PID sensor from condensing moisture for added reliability in severe weather conditions. In addition, the PID sensor incorporates patented Fence Electrode Technology, which virtually removes the effects of airborne humidity and protects from contamination.
The Falco VOC detector gives you cutting-edge performance; reliability, accuracy and results you can trust so you can be sure workforce and plant receive on-going maximum protection. With its humidity resistance and anti-contamination design drift is minimised and run-time extended, saving both time and cost to your business.
Offering the ultimate in safety, Falco eliminates false readings found with other competing PID technology. Its multi-coloured LED status display can be seen from a distance of twenty metres in sunlight ensuring you are clearly alerted to hazards present.
Falco has an externally located Intrinsically Safe sensor for quick and easy servicing without the need for a hot work permit. Dual certification allows Falco to be serviced and calibrated in a hazardous environment without having to remove power.
Simple to operate the Falco fixed VOC detector has an intuitive user interface. It has five magnetic switches with LED confirmation, a high contrast OLED screen and graphical interface ensuring installation and servicing are both quick and easy.
RS485 (Modbus®), 4-20 mA and Relay outputs are standard for all models. The Relay outputs are configurable for either high and low alarms, fault conditions or test cycle synchronisation.
The Falco fixed VOC detector offers the ultimate in flexibility and can be purchased as one of four detection ranges in either a pumped or diffused variant. With a diffused model, servicing costs are kept to a minimum with no pump to maintain.
