TA - Model PTG-9-RN -Radon Monitor
TA’s PTG-9-RN Radon Monitor is a sensitive, rugged, portable instrument for detection and measurement of airborne radon. Its internal subtractive two balanced ion chambers electro - meter circuit decreases background effects to negligible levels and its deionized and filtered intake reduces to negligible levels spurious effects from smoke, dust and existing ionization in the air.
Inlet and outlet hoses allow monitoring interiors of fume hoods, exhaust stacks, etc. The PTG-9-A-RN will measure airborne radon as free Radon gas (with or without Radon Daughters at user’s option) as low as 1 pCi/l.
All instruments are calibrated at the factory. Calibration check may be performed in the field with a microCurie level beta-gamma source. Chambers may be switched to additive operation to check linearity of response on a gamma calibration range. User friendly calibration controls are provided.
