Analysis and detection of gases Analysis and Measurement

Contrôlez désormais votre qualité d'air respirable partout dans le monde avec la VAR18-X.

ASCO INSTRUMENTS vous présente la toute nouvelle VAR18-X, dernière née de la gamme air respirable parmi nos analyseurs d'air respirable normés EN12021.

Cet analyseur de format réduit, n'altère en rien la qualité des mesures de sa grande soeur la VAR18.

La VAR18-X est conçue pour contrôler la qualité de l'air respirable dans les réseaux d'air comprimé à espace réduit, et pour voyager sur les sites à contrôler.

Son atout majeur : sa taille !

Elle se glisse partout, peut être transportée en cabine lors de déplacements en avion, bateau, théatre d'opérations, sous marins et bâtiments de surface (sans l'option batterie, sur secteur 230v) et assure la qualité de mesure d'une VAR18 classique grande taille, à roulette.

Elle se distingue également dans ce format par un écran 7 pouces tactileet couleur, facile à manipuler, et à lire. La VAR18-X est également capable d'assurer les mesures en continu capot supérieur fermé, ce qui était attendu pour les opérations en milieu poussiéreux notamment.

Fonctionnalités :

• Contrôle permanent de la qualité de l'air respirable suivant la teneur des gaz évoqués par la Norme EN 12021,
• Produit idéal pour une utilisation en milieu industriel, espace confinés et réduits, zones nucléaires avec sas de décontamination, milieu hospitalier, militaire, travaux sous marins.,
• Traçabilité des données, alarmes, étalonnages sur une période de 10 ans récupérables sur clé USB,
• Le port de communication Ethernet offre la possibilité de dialoguer avec votre automate ou serveur,
• Mesure des 5 valeurs de la norme EN12021

Particularités :
