• User Preparation Before Delivery of High and Low Temperature (Humidity) Test Chamber

  Nov 15, 2025

  1. Preparation for Load-bearing and Dimensional Adaptation • The load-bearing capacity of the site floor shall strictly meet the core requirement of ≥500kg/m², which is a key prerequisite for ensuring the long-term stable operation of the equipment and avoiding equipment deformation or safety hazards caused by insufficient load-bearing capacity. • It is necessary to accurately confirm the external dimensions of the test chamber specified in the technical specification in advance. Combined with the on-site actual survey of the transportation and installation path, ensure that the equipment can smoothly pass through all key passage nodes such as elevators, laboratory doors and corridors, so as to avoid delay in delivery and installation due to inconsistent dimensions. 2. Preparation for Installation Site Conditions • The floor of the installation site shall be flat without protrusions and depressions, and the ventilation conditions shall meet the basic standards for equipment operation. At the same time, there shall be no flammable, explosive, corrosive gases or dust in the environment, as such substances will seriously affect the service life of equipment components and the accuracy of test data. • Strong electromagnetic radiation sources such as high-voltage lines and large motors should be actively avoided near the equipment installation location, as strong electromagnetic interference may cause disorder of the equipment control system, thereby affecting the temperature and humidity control accuracy of the test chamber. • A floor drain that meets the drainage standards must be provided within 2 meters of the equipment's refrigeration unit. This requirement is to timely discharge the condensed water generated during the operation of the refrigeration system, so as to avoid water accumulation soaking the equipment or polluting the site environment. • Sufficient maintenance and operation space shall be reserved around the equipment in accordance with specifications. The specific requirements strictly follow the following standards: Area A ≥80cm, Area B ≥60cm, Area C ≥110cm, Area D ≥110cm. Sufficient space is a necessary guarantee for later equipment maintenance, calibration and component replacement.

• Differences between High and Low Temperature Test Chamber and Constant Temperature Test Chamber

  Nov 13, 2025

      In environmental reliability testing, high-low temperature humidity test chambers and constant temperature and humidity test chambers are easily confused due to similar names, but they differ significantly in testing capabilities, applications and technical characteristics. Accurate distinction and selection are key to ensuring valid test data. This blog will analyze the core differences and provide selection suggestions. I. Core Definition: Essential Distinction of Functional Boundaries     The core difference between the two starts with functional positioning, which directly determines the applicable scenarios.     The core of the constant temperature and humidity test chamber is "maintaining stability". It can accurately control and maintain the set temperature and humidity for a long time, and is used to simulate the long-term performance of products in specific environments, such as electronic component stability testing and textile temperature-humidity sensitivity testing. Its core requirement is "steady-state environmental performance verification".     The high-low temperature humidity test chamber focuses on "dynamic simulation". In addition to precise temperature and humidity control, it has a wide-range fluctuation capability, which can simulate environments such as high-low temperature cycles and alternating humidity and heat, such as extreme temperature differences during product transportation and diurnal temperature-humidity changes of outdoor equipment. Its core requirement is "dynamic environmental reliability verification". II. Key Differences: Multi-dimensional Analysis from Technology to Application 1. Temperature and Humidity Range and Fluctuation Capacity     The constant temperature and humidity chamber has a mild temperature and humidity range (temperature 0℃-100℃, humidity 30%-95%RH) and high control precision (temperature fluctuation ±0.5℃, humidity ±2%RH), but no extreme temperature-humidity impact capability.     The high-low temperature humidity chamber has a wider temperature and humidity coverage (temperature -70℃~200℃, humidity 10%-98%RH) and rapid change capability (heating rate 3℃/min-15℃/min, cooling rate 1℃/min-10℃/min), which can realize rapid cycle switching between "high temperature and high humidity - low temperature and low humidity"—a feature unavailable in the former. 2. Differences in Core Technical Architecture     The constant temperature and humidity chamber adopts single-stage compression refrigeration, conventional resistance heating, and steam or ultrasonic humidification. Its system design focuses on "energy saving and stability", with simple structure and low operating cost.     To meet extreme needs, the high-low temperature humidity chamber uses cascade refrigeration, rapid-heating tubes, and its humidity system includes a fast-response dehumidification module, with a thicker insulation layer on the chamber wall. Its technical complexity and manufacturing cost are much higher than the former. 3. Applicable Scenarios and Testing Purposes     The constant temperature and humidity chamber is used for steady-state environmental adaptability testing, such as electronic component aging and pharmaceutical storage simulation, to verify the performance consistency and durability of products in a fixed environment.     The high-low temperature humidity chamber focuses on dynamic reliability testing, such as high-low temperature cycling of auto parts and extreme environment simulation of aerospace products, to expose product defects (material aging, structural deformation, etc.) under drastic environmental changes.     In summary, the constant temperature and humidity chamber guards the steady-state environment, while the high-low temperature humidity chamber challenges the dynamic environment. There is no absolute advantage or disadvantage between the two. Only by matching needs, clarifying scenarios and budgets can the test truly guarantee product quality.

• Welche Leistung bietet eine Hoch- und Niedertemperatur-Schocktestkammer?

  Jun 14, 2025

  Die Hoch- und Tieftemperatur-Schlagprüfkammer ist für Zuverlässigkeitstests von Industrieprodukten bei hohen und niedrigen Temperaturen konzipiert. Sie wird eingesetzt, um die Leistung von Komponenten und Materialien in Branchen wie der Elektronik, der Automobilindustrie, der Luft- und Raumfahrt, dem Schiffbau und der Waffenindustrie sowie in Hochschulen und Forschungseinrichtungen unter wechselnden Zyklen hoher und niedriger Temperaturen zu bewerten. Zu den Hauptmerkmalen gehören:Hervorragende Leitfähigkeit: Das Legierungskabel, das aus Seltenerdelementen sowie Kupfer, Eisen, Silizium und anderen Elementen aus China hergestellt wird, wird einer speziellen Verarbeitung unterzogen, um eine um 62 % höhere Leitfähigkeit als Kupfer zu erreichen. Nach diesem Prozess vergrößert sich der Querschnitt des Legierungsleiters um das 1,28- bis 1,5-fache, wodurch die Strombelastbarkeit und der Spannungsabfall des Kabels mit denen von Kupferkabeln vergleichbar werden und Kupfer effektiv durch neue Legierungsmaterialien ersetzt wird.Überlegene mechanische Eigenschaften: Im Vergleich zu Kupferkabeln ist die Rückprallleistung in der Hoch- und Niedertemperatur-Schlagprüfkammer um 40 % geringer und die Flexibilität um 25 % höher. Darüber hinaus verfügt es über hervorragende Biegeeigenschaften, die einen deutlich kleineren Installationsradius im Vergleich zu Kupferkabeln ermöglichen und so die Installation und den Anschluss von Klemmen erleichtern. Die spezielle Formulierung und das Wärmebehandlungsverfahren reduzieren das Kriechen des Leiters unter Hitze und Druck deutlich und stellen sicher, dass die elektrischen Verbindungen des Legierungskabels genauso stabil sind wie die von Kupferkabeln.Zuverlässige Sicherheitsleistung: Die Hoch- und Tieftemperatur-Schlagprüfkammer wurde von UL in den USA streng zertifiziert und ist seit 40 Jahren in Ländern wie den USA, Kanada und Mexiko problemlos im Einsatz. Basierend auf fortschrittlicher amerikanischer Technologie wurde die Prüfkammer von mehreren inländischen Institutionen getestet und geprüft, was ihre zuverlässige Sicherheit gewährleistet.Wirtschaftliche Leistungseinsparungen: Bei gleicher elektrischer Leistung sind die direkten Anschaffungskosten von Hoch- und Tieftemperatur-Schlagprüfkammern 20 bis 30 % niedriger als die von Kupferkabeln. Da Legierungskabel nur halb so schwer sind wie Kupferkabel und über hervorragende mechanische Eigenschaften verfügen, können durch den Einsatz von Legierungskabeln die Transport- und Installationskosten bei normalen Gebäuden um mehr als 20 % und bei weitgespannten Gebäuden um über 40 % gesenkt werden. Der Einsatz von Hoch- und Tieftemperatur-Schlagprüfkammern wird einen unermesslichen Einfluss auf den Aufbau einer ressourceneffizienten Gesellschaft haben.Hervorragende Korrosionsbeständigkeit: Bei hohen Temperaturen bilden Legierungskabel sofort eine dichte Oxidschicht, die äußerst widerstandsfähig gegen verschiedene Korrosionsarten ist und sich daher für raue Umgebungen eignet. Darüber hinaus verlängern die optimierte Innenstruktur des Legierungsleiters und die Verwendung von silanvernetztem Polyethylen-Isoliermaterial die Lebensdauer von Legierungskabeln im Vergleich zu Kupferkabeln um mehr als 10 Jahre.
