The Formaldemeter Valve offers the same precise 3 parameter monitoring for low levels of hazardous formaldehyde vapours under extremes of temperature and humidity as seen in the Formaldemeter htV-M, but with the addition of an added valve to the internal manifold. This addition helps to prevent any contaminants from entering the chamber before and after a sample has been taken. This Formaldemeter is idealy suited for environments with high concentrations of interferents which may otherwise interfere with the correct operation of the unit.
