Carbon14 Air Monitor | Technical Associates

General Description
The Carbon14 Air Monitor is a sensitive, rugged, and portable instrument for detection and measurement of airborne C14. It is line operated with nominal 20 hour battery back-up. Optional inlet and outlet hoses allow monitoring interiors of fume hoods, exhaust stacks, etc. Features include: user settable units - uci/l or bq/m3 etc; wide range - digital accuracy; programmable digital readout; sensitive for occupational exposure dynamic background compensation; battery operation or ac operation; built-in high level alarm; built-in low flow alarm; built-in RS-232 computer interface. End Users: nuclear power plants, coal fired power plants, pharmaceutical labs, universities.

Technical Description
The Carbon14 Air Monitor subtractive balanced chamber electrometer circuit decreases background effects to negligible levels and its deionized and filtered intake minimizes spurious effects from smoke, dust and existing ionization in the air. It will measure airborne C14 as CO2 gas or as volatile chemicals in concentrations as low as 1 x 10-4 uCi/l of air (3.7KBq/m3). Electrometer circuit amplifies net difference between 0.7 liter tritium internal chamber and sealed background chamber of similar configuration. Battery Check, Set (calibration aid), Zero Adjust, Meter Programming. Internal or external calibration options.
