The OxyGuard PPB is specially designed for the measurement of dissolved oxygen (D.O.) at ppb levels (microgram per litre) in boiler feed water, condensate, district heating water, breweries and other types of liquid with low dissolved oxygen content.
PPB Analyser – for ppb level D.O. measurement.
PPB Analyser Hygienic – for the measurement of dissolved oxygen (D.O.) at ppb levels for hygienic applications. It is used in the beverage industry, e.g. breweries, where more than a trace of dissolved oxygen will spoil the finished product
