The automatic formaldehyde emission climate chamber allows for the automatic, timed sampling of formaldehyde emissions from board samples placed inside the environmental chamber, without manual intervention. After sampling is complete, simply remove the sample bottles for further chemical analysis. (The key feature is that external samplers are no longer needed; the sampling process is integrated into the system.)
This equipment is primarily used for the determination of free formaldehyde in consumer products such as wood products, furniture, flooring, carpets, footwear, and building and decoration materials.
Standard-sized test specimens are placed in a test chamber where temperature, humidity, airflow velocity, and air exchange rate are controlled at specific values. Formaldehyde is released from the specimens and mixes with the air in the chamber. Air is periodically drawn from the chamber and passed through a gas washing bottle containing water to determine the concentration of formaldehyde absorbed in the water. The formaldehyde concentration in the test chamber air is calculated from the formaldehyde concentration in the gas washing bottle and the volume of air drawn, expressed in milligrams per cubic meter (mg/m³). Sampling is performed periodically until the formaldehyde concentration in the test chamber reaches equilibrium.

Program-controlled automatic timed sampling eliminates manual intervention; after sampling is complete, simply remove the sampling bottle for further chemical analysis.
Temperature and humidity interlocking control prevents condensation.
Hot and cold counter-flow temperature control water tank: stable temperature control.
Imported humidity and temperature sensor: high sensor accuracy and stable performance.
High-quality refrigeration unit: imported chiller, stable operation and long service life.
Protection devices: The climate chamber and dew point water tank have high and low temperature alarm protection measures and high and low water level alarms.
Protection measures: The compressor also has overheat, overcurrent, and overpressure protection measures, ensuring safe and reliable operation of the entire machine.
Stainless steel inner chamber: The inner cavity of the constant temperature chamber uses mirror-finish stainless steel, with a smooth surface that prevents condensation and formaldehyde adsorption, ensuring detection accuracy.
The insulation material of the constant temperature chamber uses environmentally friendly materials that do not release formaldehyde. The chamber is equipped with a forced air circulation device (creating a circulating airflow) to ensure uniform temperature and humidity inside the chamber.
Electronic flow meter is used to control the flow rate, ensuring precise and stable control.
Program control, automatic sampling, sampling time and sampling interval can be set according to the test standards.

The system utilizes program-controlled automatic timed sampling, allowing the testing process to run without manual monitoring. Once the predefined sampling time is completed, you only need to remove the sample bottles for chemical analysis.
This equipment is designed to determine free formaldehyde release in various consumer products including wood products, furniture, carpets, footwear, flooring, and decorative building materials.
The environmental chamber conforms to several key standards such as ASTM D 6007, EN 717-1, ISO 12460-1-2007, LY/T 1612-2023, GB 18580-2025, and other physical/chemical test methods for wood-based panels.
Condensation is prevented using a temperature and humidity interlocking control system, supported by a hot and cold counter-flow temperature control water tank that keeps the chamber climate highly stable.
The mirror-finish stainless steel provides a smooth surface that effectively prevents condensation build-up and formaldehyde adsorption. This ensures the highest accuracy in test measurements.
The unit is equipped with high and low temperature alarms, water level indicators, and compressor safeguards including overheat, overcurrent, and overpressure protection to guarantee safe and reliable long-term operations.
