Environmental Chamber for Reference Standard Station

Product Specifications

Technical details and manufacturing context for Environmental Chamber

Definition

The Environmental Chamber is a critical component of the Reference Standard Station that provides precise control over temperature, humidity, and sometimes other environmental factors. It creates stable, repeatable conditions necessary for calibrating instruments, testing material properties, or validating product performance under various simulated environments. Within the station, it ensures measurement accuracy by eliminating external environmental variables. The chamber is constructed with a stainless steel interior (SUS304 per ASTM A240) for corrosion resistance and an insulated steel exterior (SPCC per JIS G3141) with polyurethane foam insulation. It is available in volumes from 100 to 1000 liters, with a temperature range of -70°C to 150°C, temperature uniformity of ±0.5 to 2.0°C, and temperature fluctuation of ±0.1 to 0.5°C, per IEC 60068-3-5. Humidity ranges from 10% to 98% RH with a tolerance of ±2 to 3% RH at mid-range, per IEC 60068-2-78 and IEC 60068-3-6. Heating and cooling rates are 1 to 5°C/min, depending on the system. The chamber operates on a 220/380 V AC, 3-phase, 50/60 Hz power supply, with rated power from 5 to 20 kW. Weight ranges from 200 to 1500 kg, and noise level is ≤65 dB(A) at 1 m distance per ISO 3744. These specifications are reference ranges; actual values must be confirmed with the legal manufacturer for the specific model and application. The chamber is designed for integration into a Reference Standard Station, where it provides a controlled environment for testing and calibration. It is not a standalone product but a component that must be selected based on test specimen size and required environmental conditions. The chamber's performance is critical for test repeatability and measurement accuracy, and it must be verified against relevant standards such as IEC 60068-2-1, IEC 60068-2-2, and IEC 60068-3-5. Always consult the manufacturer for model-specific data and compliance.

Working Principle

The chamber uses heating elements, refrigeration systems, and humidification/dehumidification units to achieve target conditions. Sensors monitor internal parameters and provide feedback to a control system that adjusts heating, cooling, and moisture levels to maintain precise, stable environmental settings as required by the testing or calibration protocol. The control system ensures that temperature and humidity remain within specified tolerances, and the chamber's insulation minimizes external influences. The working principle is based on closed-loop control, where sensors continuously measure conditions and the controller adjusts actuators to correct deviations. This allows the chamber to simulate a wide range of environmental conditions, from extreme cold to high heat and humidity, with high repeatability. The chamber's design includes a stainless steel interior for easy cleaning and corrosion resistance, and the exterior is insulated to reduce energy consumption and maintain stability. The system is capable of rapid heating and cooling rates, enabling efficient testing cycles. The chamber's performance is verified through calibration and testing procedures, and it is essential to follow the manufacturer's guidelines for operation and maintenance to ensure accurate results.
