PTG-9RN Radon Monitor

PTG-9RN Radon Monitor by Technical AssociatesThe PTG-9-RN Radon Monitor is a sensitive, rugged, portable instrument for detection and measurement of airborne radon. The subtractive balanced chamber electro - meter circuit decreases background effects to negligible levels. The deionized and filtered intake greatly reduces 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-RN will measure airborne radon as free Radon gas (with or without Radon Daughters at users 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.
