Radiation
Source
Cobalt-57 (Min. 10
mCi, Max. 12 mCi, 444 MBq)
RMD's LPA-1 analyzer
radioactive source is a 12 mCi, Cobalt 57 isotope. Co-57 gamma
ray energies (122 Kev) are more efficient (at least 10 times)
than those of Cd-109 (22-26 Kev and 88 Kev) source for production
of K-shell lead x-rays, which are recommended by HUD chapter
7 for measurement of lead in paint. Therefore, the measurement
time is shorter using a Co-57 source
Detector
The LPA-1 analyzer utilizes
a "room-temperature" detector, CdTe, for its x-ray analysis
that operates in a wide, 20-120° F, thermal range without
any cooling requirements. The LPA-1 analyzer's ability to operate
without cooling eliminates a cooling down period for stability
at the beginning of a job that would result in extra time added
to inspections.
Operation
The LPA-1 XRF system
has the capability of setting abatement levels from 0.4-2.0
mg/cm2 for automatic determination of the lead condition as
either positive or negative with 95% confidence according to
a PCS approved mode of operation.
Memory
The LPA-1 can data log
up to 4000 data points and is easily down loaded through an
RS-232 serial interface port for report generation with the
WindowsTM based Report Generation Software.
Software
The WindowTM
based interactive graphic software is considered to the most
comprehensive, universally applicable lead paint report generation
system available. The software is included in the LPA-1 instrument
package and upgrades are free for as long as you own the instrument.
Warranty
2-year parts and labor
warranty with a life time warranty on the calibration of the
instrument. RMD Instruments, LLC also offer upgrades of the
software and system upgrades free of charge for as long as you
own your instrument.
