|Precision Airborne Alpha Radiation Detection Instrument|
|The Femto-Tech, Inc. model
CRM-510 is a precision airborne alpha radiation detection instrument
based on the same field proven pulsed ion chamber technology of
previous models R210F and RS410F. Due to a unique patented
electrometer and open grid probe design, the model CRM-510 is highly
suited for a wide range of radon measurement applications. Because of
the low current requirements of the electrometer detector and on-board
computer, the model CRM-510 is truly a portable self-contained
continuous radon monitor that can read and store test data for four
days of stand-alone operation. In this "passive" mode of
operation the model CRM-510 is uniquely suited for screening and
follow-up type testing.
The full function computer system incorporated in the model CRM-510 provides the operator with a highly flexible radon detection instrument and data logger operating system, while still maintaining the simplicity of operation for which Femto-Tech instruments are noted. In addition to the measurement and storage of radon data, the highly sophisticated on-chip peripheral capabilities of the micro controller (MCU) used in the CRM-510 provide for the measurement and storage of temperature, barometric pressure, and relative humidity. This multidimensional data acquisition capability provides the tester with a unique data base for evaluating the validity of short term radon measurements.
