Environmental Formaldehyde Test Chamber For Emission Test With
Programmable
HD-F801-3 Formaldehyde Test Chamber.pdf
Product Description:
Formaldehyde test chamber, mainly used for interior decoration materials (such as: standard
climate simulation for formaldehyde emission detection of man-made
panels, carpets, paints, wallpapers, curtains, etc.) and
manufacturing of standard test chambers for reasonable release of
materials Formaldehyde, and then determine the amount of
formaldehyde released.
Working principle:
Put sample of 1 square meter area into the temperature chamber
which controlled control in a certain value of temperature,
relative humidity, air velocity. The formaldehyde released from
samples, mixed with the air in the cabinet, regular extraction in
the air, and the air will be drawn through the absorption bottle is
filled with distilled water, all the formaldehyde in air dissolve
in the water; Measure the amount of formaldehyde in the absorption
solution and extraction of air volume, and show it by micrograms
per cubic meter (mg/m after), calculate the amount of formaldehyde
in per cubic meter of air. Sampling is cyclical, until the test the
formaldehyde concentration in the oven to reach equilibrium.

Features:
1. Box inner chamber is made of stainless steel, the surface is
smooth and no condensation, adsorption formaldehyde, guarantee the
accuracy. The thermostat box is made of hard foaming material. The
door is sealed with silicone rubber, and it’s good thermal
insulation performance and sealing performance. Box is equipped
with forced air circulation device (it’s form the circulating air
flow), to ensure the consistent temperature and humidity balance of
the main structure in the cabinet: The inner tank is a mirror
stainless steel test tank., the outer for insulation casing,
compact, clean, efficient, energy saving, not only reduces the
energy consumption and reduce the time of the balance of the
equipment.
2. Using a 7 inch touch screen as personnel operating equipment
dialogue interface, intuitive and convenient. Directly to set up
and display the temperature in the cabinet, relative humidity,
temperature compensation, compensation, dew point deviation, dew
point temperature deviation, adopts imported sensors, and can
automatically record and control curve drawing. Special control
configuration software, the realization of system control, program
setting, dynamic data display and historical data playback, fault
recording, alarm Settings, and other functions.
3. It adopts industrial module and imported programmable
controller, good operation stability and reliability, It can ensure
the trouble-free operation for a long time and improve the service
life of equipment, also reducing the operation cost of the
equipment. And breakdown self check and prompt functions. It is
convenient for users understanding the running situation of
equipment, maintenance is simple and convenient.
4. The control program and operation interface are in accordance
with the relevant test standard optimization design and simplely
convenient operation.
5. It changed the existing reciprocating humidify the fog, dew
point method is used to humidify, make the casing humidity change
smoothly, thus greatly improve the accuracy of moisture control.
6. It adopted the imported film platinum resistor as temperature
sensor, high precision, stable performance..
7. With advanced technology in the heat exchanger and high thermal
efficiency, reduce the temperature gradient.
8. The compressor, such as temperature and humidity sensor,
controller, relay device and so on, these spare parts adopted
imported components.
9. Protection device: climate, water tank has high and low
temperature dew point alarm protection with high and low water
level alarm protective measures.
10.Integration of the whole machine structure is compact;
Installation, debugging and use is very simple.
