The femto-TECH, INC. model CRM-510LP/CO 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-510LP/CO 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-510LP/CO is truly a portable self-contained continuous radon monitor that can read and store test data for eight days of stand-alone operation. In this "passive" mode of operation the model CRM-510LP/CO is uniquely suited for screening and follow-up type testing.

The full function computer system incorporated in the model CRM-510LP/CO 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-510LP/CO 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.

Why measure carbon monoxide and radon?

The EPA lists radon as the number one environmental health risk homeowners may face. Next on the list of health risk concerns is carbon monoxide. While radon is a carcinogen, carbon monoxide is a poisonous gas which can cause harm very rapidly. During protocol radon tests, houses are placed under closed house conditions for a minimum of 48 hours enabling better detection data on varying levels of radon. If carbon monoxide is measured during the above conditions, chances of detection are likely to improve. If homeowners are concerned about the number one risk, they probably also have concerns about the second major health risk.
