Wireless interface
phx21™ takes its input and presents all of its output through a wireless interface
to a PDA. The absence of input buttons, displays, switches, keypads or physical
interface enables the phx21™ to be smaller, lighter, less susceptible to breakage
and easier to modernize and upgrade.
Hands-off calibration (with Cal3.0™)
phx21™ can be set for any type of calibration (daily, precision or drift)
to be automatically performed. System would automatically ignite phx21™, monitor/
confirm warm-up time, administer calibration gases and then perform electronic calibration,
test results and record and store all results. This means that the phx21™
will be more efficient to operate and ensure against human error.
Method21 calibration failsafe
phx21™ will compare internal calendar with its calibration records and display
a notice to the operator when any calibration event (such as daily calibration,
quarterly precision calibration or periodic drift assessment) is required but has
not been performed. Owner would have the option of setting calibration requirements
in the system and creating either the option to override the failsafe notice OR
disable monitoring until calibrations are performed. This means that a Technician
cannot inadvertently use a phx21™ that has not been properly calibrated.
Automatic back-up ignition with failure notice
If primary ignition source fails (during warm-up or routine operation) a back-up
source will ignite the detector AND display a recurring message to the operator
that maintenance is required on the primary ignition source.
Onboard maintenance records
All maintenance records will be stored directly in the phx21™ onboard computer.
This will enable the owner to have a ready source of all maintenance that has been
performed on each phx21™ for its entire lifetime.
Automatic pump blockage protection
If the probe flow is blocked by moisture, water, product, dirt, dust, grease, debris,
paint, the tip of a Technicians finger, the sample line is kinked, the filter is
removed or a leak develops in the sample line the phx21™ will automatically shut
down and notify the user.
Status Display
The phx21™ will automatically display notices indicating system needs or the
necessity of doing routine, periodic maintenance.
