Technical Associates VAP-X-Radon Monitor is a sensitive, rugged, portable instrument for the detection and measurement of  Radon vapor in the soil. Its subtractive balanced chamber electrometer circuit decreases background effects to negligible levels and its deionized and filtered intake reduces to negligible levels spurious effects from dust and existing ionization in soil air. It is battery or AC-operated.

Inlet and outlet hoses are provided. The VAP-X-Radon will measure airborne Radon in any form: water vapor, hydrogen gas, or volatile chemicals in concentrations as low as 1 x 10-5 uCi/cc of air. (370 KBq/m3)

All instruments are calibrated at the factory. A calibration check may be performed in the field with a microCurie level Beta or Gamma source. The background chamber may be disconnected to check the linearity of response on a gamma calibration range. User-friendly calibration controls are provided.
