Its' subtractive balanced chamber 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. The PTG-7L is the bench-top version of the PTG-7. It is line operated and it maybe left on permanently without fear of ``running out of battery''. Inlet and outlet hoses allow monitoring interiors of fume hoods, exhaust stacks, etc. The PTG-7 will measure airborne tritium as free hydrogen or as volatile chemicals in concentrations as low as 1 x 10-6 uCi/cc of air. (37 KBq/m3) All instruments are calibrated at the factory. Calibration check may be performed in the field with a microCurie level beta source. Chambers may be switched to additive operation to check linearity of response on a gamma calibration range. User friendly calibration controls are provided.
