The usage is also very simple. Put a standard size test piece into a test chamber where the temperature, humidity, air flow rate and air replacement rate are controlled at a certain value. Formaldehyde is released from the test piece and mixed with the air in the chamber. The air in the chamber is periodically extracted, and the air is extracted from the chamber through a gas washing bottle filled with water to measure the concentration of formaldehyde absorbed in the water. The formaldehyde concentration in the air in the test chamber is calculated from the formaldehyde concentration in the gas washing bottle and the volume of air extracted, expressed in milligrams per cubic meter (mg/m3). Sampling is periodic until the formaldehyde concentration in the test chamber reaches equilibrium.
At present, Shenzhen CTI Testing Group/Dongguan Zhongding/Tianjin Shengbin Testing/Shandong Tai'an Tianzheng Testing and other testing institutions have purchased this equipment, which operates 24 hours a day. It has been strictly tested by customers, and the equipment experience is full. The most important thing is After retail!
