ION Science Falco 2 TAC VOC Monitor

The ION Science Falco 2 TAC Intrinsically Safe Fixed VOC Gas Detectors represent the pinnacle of fixed photoionization detection (PID) technology. It is purpose-built for continuous monitoring of volatile organic compounds (VOCs) and Total Aromatic Compounds (TACs) in hazardous locations.

When evaluating equipment for hazardous environments, many safety managers are now considering the advanced ION Science Falco 2 TAC Intrinsically Safe Fixed VOC Gas Detectors. Moreover, they are certified for ATEX, IECEx, and North American Zone 1 environments.

These devices provide reliable, life-saving ambient air safety telemetry across refineries, chemical plants, and heavy industrial facilities. In these places, explosive or toxic gases pose an everyday risk.

In the field, the Falco 2 series delivers unrivaled operational resilience through its patented Typhoon Technology. This prevents condensing moisture from disrupting the PID sensor. Furthermore, Fence Electrode Technology mitigates dust contamination. Users can effortlessly navigate settings without a hot work permit using the high-contrast white-on-black OLED display. The tamper-proof 5-magnetic-switch interface is operated via a magnetic pencil—ensuring the flameproof ExD housing remains completely sealed during maintenance.

FAQs:

What is the primary difference between the Falco 2 Standard and the Falco 2 TAC?
The standard Falco 2 uses a 10.6 eV lamp to broadly detect over 700 volatile organic compounds. In contrast, the Falco 2 TAC utilizes a 10.0 eV lamp. This lamp is specifically tuned to filter out straight-chain hydrocarbons and pinpoint Total Aromatic Compounds (TACs) like Benzene.

Can the Falco 2 be calibrated and serviced inside a hazardous area?
Yes. Thanks to its dual certification and an externally located, intrinsically safe sensor head, routine maintenance, lamp cleaning, and calibrations can be executed safely in hazardous zones. This is possible without isolating the main power supply.

How does Typhoon Technology protect the sensor?
Typhoon Technology is an advanced internal design mechanism. It prevents condensing moisture from accumulating on the PID lamp window. As a result, it effectively eliminates false positive readings common in humid or outdoor coastal environments.

What are the maximum sampling distances for the pumped version?
The Falco 2 Pumped variant features an integrated flow system running at 260 cc/min. This allows it to accurately sample gases from up to 20 meters away using standard non-reactive PTFE or PVDF tubing.
