CRM-510


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.
