Abstract

The invention refers to a photometric process measurement arrangement (10) with a photometric immersion probe (20). The photometric immersion probe (20) comprises a photometer flashlight source (61) for providing photometric light impulses with a continuous spectrum, an impulse energy capacitor (33) for storing the electric impulse energy and having an actual electric capacitor's voltage (U), an impulse ignition switch (36) electrically arranged between the impulse energy capacitor (33) and the photometer flashlight source (61), an ignition voltage memory (45) memorizing an ignition voltage value (Ui), and a falling-edge ignition trigger (42) which closes the impulse ignition switch (36) in the moment when the falling actual electric capacitor's voltage (U) equals the memorized ignition voltage value (Ui).
