IntroductionHigh – low temperature and low pressure test chamber is a simulation of high altitude, high altitude, (plateau area) climate for storage and transport reliability test, and can be simultaneously electrified on the test piece for electrical performance parameters of the test equipment. Applicable to the defense industry, aerospace industry automation components, automotive parts, batteries, flat panel display group industry and related products for high temperature, low temperature, height (not higher than 30,000 m above sea level or 45,000 m) and high and low temperature cycling test, temperature and altitude of the integrated test, high and low temperature test this chamber can be used for heat dissipation test specimens and non-heat dissipation test specimen test.Safety & ProtectionsProtection contre les sous-tensions, les surtensions, les phases manquantes et les erreurs de séquence de phases ; 3 types de protection contre la surchauffe Protection contre les courts-circuits du chauffage ; Surpression/surcharge/protection du compresseur : Protection contre les défauts de l'humidificateur : Protection contre la surcharge/surchauffe du moteur du ventilateur ; Protection contre les surintensités du panneau, protection contre les fuites à la terre : protection contre les surcharges de la pompe à vide : protection contre la pression inadéquate de l'air comprimé.ApplicationPrincipalement utilisé dans l'aviation, l'aérospatiale, l'information, l'électronique et d'autres domaines pour déterminer l'instrumentation, les produits électroniques, les matériaux, les composants, l'équipement, etc. dans des conditions simples ou simultanées de basse pression, haute température, basse température pour l'adaptabilité environnementale et le test de fiabilité ou les données techniques mesurées des échantillons.PossibilitésSpecial cable port;
