Your report on Product(s), Selling Lead(s) will be sent to EC21 Administrators once submitted. Then, Administrators will investigate and then take appropriate actions.
The VOC Emissions Environmental Chamber is
mainly used to study the VOC emission rules of various wood-based panels,
composite wood floors, carpets, carpet fillers and other interior materials, to
detect formaldehyde emissions, and to classify test products; The predictive
model evaluates indoor air quality.
Working principle: Put a sample with a
surface area of 1 square meter into the temperature chamber to control the
temperature, relative humidity, and a certain value of the air flow rate. The
formaldehyde in the sample is released, mixed with air, periodically extracted
in the air, and the air extracted through the absorption bottle is filled with
distilled water, and all the formaldehyde in the air is dissolved in water, and
the amount of formaldehyde and the air in the absorption solution are measured.
The volume of extraction, expressed in micrograms per cubic meter (mg / m),
calculates the amount of formaldehyde per cubic meter of air. The sampling is
cyclic until the formaldehyde concentration in the test chamber is balanced.
Main Feature:
1. The stainless steel in the box body has
a smooth surface, no exposure, no adsorption of formaldehyde, and the accuracy
of the test is guaranteed.
2. 7-inch touch screen control system,
intuitive and convenient.
3. Self-test and prompt function, which is
convenient for users to understand the operation of the equipment, and the
maintenance is simple and convenient.
4. The control program and operation
interface are optimized according to relevant test standards, and the operation
is simple and convenient.
5. The humidity inside the box is stable,
and the humidity control accuracy is improved.
6. High-precision platinum resistance is
used as the temperature sensor with high precision and stable performance.
7. The heat exchange efficiency is high and
the temperature gradient is lowered.
8. Protection device: Both high and low
temperature alarm protection measures and high and low water level alarm
protection measures are available.
9. The whole machine is integrated,
compact, easy to install, debug and use.
