Furniture Formaldehyde Content Testing Machine Formaldehyde Testing Chamber / Climate Test Chamber High Accuracy

Formaldehyde Test Chambers

 
Description:
Formaldehyde Test Chamber is used to test formaldehyde emission of various wood-based panel, composite wood flooring, carpet, carpet padding, and other interior decoration materials, also other building materials under constant temperature humidity.
 
Executive standard:
GB18580—2001
GB18584—2001
GB18587—2001
GB17657—2013
ASTM D6007—02
 
Working principle:
The temperature, relative humidity, air velocity and air displacement rate of the sample with 1 square meter surface area are controlled in the climatic box with a certain value.Formaldehyde is released from the sample and mixed with the air in the box. The air in the box is extracted regularly. The extracted air is passed through the absorption bottle containing distilled water, and all the formaldehyde in the air is dissolved into the water.Determine the amount of formaldehyde in the absorption solution and the volume of air extracted, expressed in milligrams per cubic meter (mg/m), calculate the amount of formaldehyde per cubic meter of air.The sampling is periodic until the formaldehyde concentration in the test chamber reaches an 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.
