Air check 
Advantage
Freon, C4F6, & PFC Gas Monitor
- Detects Freon, C4F6, and other PFC’s at TLV levels
- “Smart” sensor electronics continuously checks sensor, flow and system status
- Built-in user selectable local dual level alarms with relay output
- Local gas concentration digital display
- 4-20 mA analog output
- Low cost renewable sensor cell
- Enhanced self-diagnostics capability decreases downtime and maintenance costs
The Air check
Freon monitor is a compact, tractive
continuous gas monitoring system designed to monitor
in hazardous areas. The system uses our proprietary
renewable electrochemical sensor cell combined
with a long life pyrolizer to provide tremely
sensitive and specific Freon, C4F6 & PFC monitoring.
Unlike traditional LEL solid-state detectors, the
Air check
pyrolizer technology is tremely
sensitive and capable of detecting parts-per-million
concentrations of Freon, C4F6 & other PFC’s
at TLV levels without being affected by humidity
or other environmental conditions.
The heart of
the monitoring system is a long life pyrolizer
designed to convert Freon to an electrochemically
active gas detected on PureAire’s renewable sensor
cell. And the low cost renewable sensor cell offers
the lowest annual preventative maintenance materials
at about $75 per year for electrolyte replacement.
The Air check
electronics, pyrolizer,
sample pump and sensor cell are housed in a Nema 4 weather proof enclosure.
The instrument’s “smart” circuitry continuously
monitors sensor cell status and sampling system
performance. Continuous sensor cell operation is
transmitted via 4-20mA signal to PureAire controllers,
PLC’s or remote alarm systems. Should a system
error occur, the Air check
outputs a specific
mA signal to remote alarm/control systems to immediately
alert control room personnel.
Low Annual Operation Cost
The PureAire Air check
has the lowest
annual maintenance costs of any gas monitoring
system on the market. PureAire’s Renewable Sensor
cells are easily recharged with electrolyte right
in the field at approximately 20% of the
cost of disposable sensor cell type systems. Recharge
costs typically run about $35.00 per sensor every
6 months. Combined with our built-in, low power
pyrolizer, and long life sample pump, the Air check will lower your annual operation costs. When
compared to competitive gas monitors, it will pay
for itself in just a few years.
Connects to DCS and PLC Controls
The Air check
Freon monitor
is 24VDC powered and transmits continuous gas concentration
levels to any distributive control system, programmable
logic controller or PureAire’s proprietary single
and multichannel controllers. The Air check
Monitor can be operated remote up to 1,000 meters,
0.6 miles from centralized distributive control
systems.
Fenceline Monitor Detects Hydrogen Fluoride Releases
A sensitive and specific fenceline monitoring system for the detection and measurement of hydrogen fluoride (HF) is now available from PureAire Monitoring Systems...
System Helps Control Odors from Municipal Waste Treatment Facilities
A highly effective, field-proven system for helping control hydrogen sulfide (H2S) emissions from municipal waster water treatment plants is now available from PureAire Monitoring Systems. Designed for use in 100% condensing RH environments, the PureAire Chlorine Monitor responds almost instantaneously to changes in chlorine concentration...
Gas Monitor Detects Fluorine Odors in Scrubbers, Exhaust Stacks, and Work Areas
An extremely sensitive monitoring system for the detection and measurement of fluorine (F2) is available from PureAire Monitoring Systems. Ideal for monitoring scrubbers, exhaust stacks, process areas, and other locations where fluorine may be present, the PureAire Fluorine Monitoring System measures concentrations as low as 50 PPB, yet will not react to hydrogen or alcohol-based cleaning solvents such as IPA. Moreover, the system’s low-level measurement accuracy is unaffected by changes in ambient temperature or humidity.
