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.
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 Corp also offer upgrades of the software and system upgrades free of charge for as long as you own your instrument.
All claims of performance are verified by the Performance Characteristic Sheet, Edition No.: 4, developed by QuanTech, Inc., under a contract from the U.S. Department of Housing and Urban Development (HUD).
