ASTMD6007 ISO16000 Formaldehyde Climate Chamber HCHO Emission Climate Tester Aldehyde Cabinet Hcho Environmental Test Machine
Purpose and Scope of Application
The Formaldehyde Climate Chamber is a testing device developed for the determination of formaldehyde emissions, designed in accordance with national standards (GB 18580-2025, LY/T 1612-2023), American standards (ASTM D6007-2), European standards (EN 717-1), international standards (ISO 16000-9), and German standards (DIN EN 16516-2018). It is suitable for measuring formaldehyde emissions from a wide range of materials, including various types of man-made boards, engineered wood flooring, interior decoration materials (such as carpets, carpet underlays, and carpet adhesives), furniture, automotive interior components, and architectural decorative materials. Additionally, it can be utilized for the constant-temperature and constant-humidity conditioning of wood or man-made boards, as well as for the detection of volatile hazardous gases in other building materials.
The level of formaldehyde emission from man-made boards serves as a critical indicator of their quality, directly impacting both environmental pollution and human health. The 1 m³ Formaldehyde Climate Chamber testing method is a globally adopted standard for assessing formaldehyde emissions in interior decoration and renovation materials. Its key feature lies in its ability to simulate actual indoor climatic environments; consequently, the test results obtained are highly representative of real-world conditions, ensuring their authenticity and reliability.
This equipment employs an intelligent, integrated humidity control system that combines the principles of the dry-and-wet bulb method with the dew-point method:
Intelligent Integrated Humidity Control Method (Dry-and-Wet Bulb & Dew Point):This method synthesizes the advantages of both the dry-and-wet bulb technique and the dew-point technique. Initially, it utilizes the dry-and-wet bulb method to rapidly achieve the target humidity level—typically within one hour. Once the target humidity is reached, the system automatically switches to the dew-point method to provide auxiliary humidity control. This approach ensures exceptional stability, with humidity fluctuations generally remaining within ±2%—a performance level significantly superior to the ±3% tolerance required by relevant standards.

Working Principle and Product Features
Working Principle:A sample with a surface area of 1 square meter is placed inside a climate chamber where temperature, relative humidity, airflow velocity, and air exchange rate are maintained at specific, controlled values. Formaldehyde is released from the sample and mixes with the air inside the chamber. Air is periodically drawn from the chamber and passed through an absorption bottle containing distilled water, allowing all the formaldehyde present in the air to dissolve into the water. The quantity of formaldehyde in the absorption solution and the volume of air sampled are measured to calculate the formaldehyde concentration per cubic meter of air, expressed in milligrams per cubic meter (mg/m³). Sampling is conducted cyclically until the formaldehyde concentration within the test chamber reaches a state of equilibrium.

Product Features and Advantages
1. Chamber Interior:The inner chamber is constructed from 1.5 mm thick, mirror-polished 304 stainless steel. This substantial thickness ensures the equipment's stability, durability, and superior airtightness. The smooth surface prevents condensation and does not adsorb formaldehyde, thereby guaranteeing the accuracy of the test results. The constant-temperature housing utilizes rigid foam insulation, while the chamber door features a silicone rubber sealing strip, providing excellent thermal insulation and sealing performance. The chamber is equipped with a forced-air circulation system (generating a circulating airflow) to ensure uniform and consistent temperature and humidity distribution throughout the interior. Main Structure: The unit consists of a mirror-polished stainless steel inner test chamber encased within an insulated outer housing. This compact, clean, efficient, and energy-saving design not only reduces energy consumption but also minimizes the time required for the equipment to reach equilibrium.
2. User Interface: The equipment features a 7-inch touch screen that serves as the human-machine interface, offering intuitive and convenient operation. Users can directly set and digitally monitor parameters such as internal temperature, relative humidity, temperature compensation, dew point compensation, dew point deviation, and temperature deviation. The system utilizes high-quality imported sensors and is capable of automatically recording data and plotting control curves. Configured with dedicated control software, the system enables comprehensive functions including system control, program scheduling, dynamic data display, historical data playback, fault logging, and alarm settings.
3. Control System:The equipment employs industrial-grade modules and an imported programmable logic controller (PLC), ensuring exceptional operational stability and reliability. This design guarantees long-term, trouble-free operation, extends the equipment's service life, and reduces operating costs. Furthermore, the system features self-diagnostic and fault-alert functions, allowing users to easily monitor the equipment's operational status and facilitating simple, convenient maintenance.
4. Software and Interface Design: The control programs and user interface have been optimized in accordance with relevant testing standards, ensuring simple, straightforward, and convenient operation.
5. Employs an intelligent, integrated humidity control method combining both wet-bulb and dew-point techniques, ensuring smooth humidity transitions within the chamber and thereby significantly enhancing humidity control precision.
6. Utilizes a thin-film, high-precision platinum resistance thermometer as the temperature sensor, offering high accuracy and stable performance.
7. The interior of the chamber features a heat exchanger manufactured using advanced technology, ensuring high heat exchange efficiency and minimizing temperature gradients.
8. Key components—including the Aspera compressor, Siemens temperature and humidity acquisition module, Siemens industrial PLC controller, and relays—are all imported parts.
9. Safety Protection: Both the climate chamber and the dew-point water tank are equipped with comprehensive safety measures, including high/low temperature alarms and high/low water level alarms.
10. The unit features an integrated, compact design; installation, commissioning, and operation are exceptionally simple.
11. Includes a standard-issue water replenishment pump with one-touch operation, facilitating convenient replacement of clean water to boost operational efficiency and ease of use for the operator.
