VOC emission chamber TPV-60

This equipment is used to test the emission of harmful substances such as volatile organic compounds, total volatile organic compounds (TVOC), benzene, toluene, the sum of xylene and ethylbenzene, carbon disulfide and formaldehyde. It is mainly suitable for plastic runways, coatings, adhesives, automotive interiors, furniture, artificial panels, floor coating materials, electronic and electrical products, interior decoration materials, etc.
This equipment is equipped with two standard test chambers, which can test multiple samples at the same time, providing high work efficiency.

WORKING PRINCIPLE
Place the sample in a test chamber with specified temperature, humidity and ventilation conditions. After a certain period of time, the emission of harmful substances released by the sample is determined by detecting the concentration of harmful substances in the chamber air.

FEATURES
· The interior is a mirror stainless steel test chamber, with a smooth surface that does not condensate or adsorb, ensuring detection accuracy; the outer layer made of hard foam material, and the door is made of silicone rubber sealing strips, which have good thermal insulation and sealing properties. It not only reduces energy consumption but also reduces the balancing time of the equipment.
· The door of the chamber is made of silicone rubber sealing strips, which have good thermal insulation and sealing properties. The box is equipped with a forced air circulation device (to form a circulating air flow) to ensure a uniform temperature and humidity inside the chamber.
· Clean the constant temperature and humidity air supply system, an integrated device for high clean air treatment and humidity adjustment.
· The equipment is equipped with full protection devices and system safe operation protection devices, making the equipment operation more reliable and safer.
· The heat exchanger technology is advanced. The heat transfer efficiency is high and the temperature gradient is small.
· The temperature control of the temperature regulating water tank is stable. The water tank has high and low temperature alarms and high and low water level alarms.
· The temperature and humidity sensor has high accuracy and stable performance.
· Imported refrigerator, stable operation and long service life.
· The compressor also has overheating, overcurrent, and overpressure protection measures, making the entire equipment safe and reliable in operation.
· The equipment adopts advanced jacketed structure, which is compact, clean, efficient and energy-saving.
