- CONSULTER

Le Hantek HT824 est un calibrateur de processus multifonctionnel avec une précision et une stabilité élevées.
Valable pour l'étalonnage sur site des instruments utilisés dans les équipements industriels et de laboratoire.
Il dispose de fonctions puissantes permettant de simuler la tension de sortie en volts ou en millivolts, le courant en milliampères et de nombreux types de signaux électriques nécessaires à la mesure et au contrôle dans les processus de commande industriels.
Vous pouvez également tester ou simuler des signaux de type TC et RTD.
