摘要： The sample and the reagent required for titration are fed into a titration vessel (1), the reagent and/or sample being supplied intermittently in the form of pulses of liquid. Toward this end, a controlled valve (9) is provided in the supply line (4) for the reagent. The opening and closing times of this valve (9) and, hence, the frequency and duration of the pulses of liquid, are chosen such that the ratio of the average sample flow to the average reagent flow is sufficient to achieve the ratio of sample to the reagent at the equivalence point. This renders continuous titration possible, for which only one pump (7) is needed, which does not require any complex servo system and, therefore, has a low energy consumption.

摘要： A fire alarm having an electronic evaluator, an optical module, a temperature sensor, and at least one combustion gas sensor, where the electronic evaluator diagnoses one of a plurality of fire types and selects an application-specific algorithm based on the diagnosed fire type. The electronic evaluator uses the signals from the sensors to diagnose at least one of a plurality of types of fire. The fire alarm may have at least one polarization filter which may be an active polarizer with electrically adjustable polarization plane.
