Abstract
Method of measuring constituents in a fluid which may be gaseous or liquid, which dispenses with calibration procedures which are performed at the expense of the measuring time. The measuring apparatus is continuously supplied with a known amount of constituents from a calibration source, which calibration amount is mixed with the fluid to be measured. Subsequently, a part of the constituents of the mixture is led to a detector, and the resulting measuring signal is compared to a reference signal for adjusting a control device to ensure that the amount of constituents which reaches the detector is the correct value. The setting of the control device is an output signal useful in unattended measuring stations for water and air pollution.
