Product Introduction: the limited release of formaldehyde in interior decoration materials is a hot issue of environmental protection that is widely concerned by countries all over the world. The amount of formaldehyde released from various interior decoration materials (such as wood-based panels, carpets, paints, wallpapers, curtains, etc.) is an important indicator to measure the quality of their products, which is related to the pollution of products to the environment and the impact of human health. 1m3 formaldehyde emission climate box detection method is a standard method widely used abroad to detect the formaldehyde emission of indoor decoration and decoration materials. Its characteristic is to simulate the indoor climate environment, and the detection results are closer to reality, so it is true and reliable

this product has been used by the national wood-based panel quality supervision and inspection center, the customs, and the import and export quarantine and Inspection Bureau. Its technical performance indicators comply with the national standard - formaldehyde emission limit in wood-based panels and their products for interior decoration materials (GB18580-2001) and the national environmental standard product industry standard "technical requirements for environmental labeling products artificial wood panels" (HJBZ). Veous-m 1m3 formaldehyde emission detection climate box is a new generation product launched after adopting a brand-new design on the basis of the feedback from the original users that the beneficial conditions for the export of China's plastic extruders are constantly increasing. The product has beautiful appearance, excellent manufacture, reliable detection and control system, and its performance and quality have passed the metrological certification of "national standard Jinan gold assay Jinan impact testing machine manufacturer quasi material research center"

scope of application: it is applicable to the determination of formaldehyde emission from various wood-based panels, composite wood floors and other indoor decorative materials, the constant temperature and humidity balance treatment of wood or wood-based panels, and the detection of volatile harmful gases in other building materials

product features:

· instrument digital display: the real temperature and humidity data in the box can be directly read through the instrument

· advanced technology of heat exchanger: high heat exchange efficiency and small temperature gradient

· cold and hot temperature regulating water tank: stable temperature control

· dew point temperature adjust air humidity: the humidity is uniform and does not condense at the corresponding temperature

· advanced humidity temperature humidity sensor: the sensor has high accuracy and stable performance

· oil free magnetic pump: the water circulation system adopts American oil-free magnetic pump, and the wet air does not affect the gas detection in the box

· high quality refrigerator: imported refrigerator with stable operation and long service life

· low water level protection: constant temperature and dew point water tanks have low water level alarm

· stainless steel inner box: the inner wall surface is smooth and does not absorb formaldehyde

# gas analysis formaldehyde tester ++++++++++++++++++++++

overview:

the basic principle of the instrument is: place a test sample with a certain exposure area in the test room where the temperature, humidity, air flow and pressure are controlled within the specified range. Formaldehyde is released from the test sample and mixed with the air in the test room, Extract the mixed gas continuously from the detection room for 4 hours and pass through the gas absorption bottle. Finally, the content of formaldehyde was determined by spectrophotometer. The control system of temperature, humidity and pressure in the air chamber adopts industrial computer for real-time control. The gas source is purified, the whole gas path is made of high stability polymer materials, and the gas chamber is made of su304 stainless steel, which does not adsorb formaldehyde and does not interfere with the measurement. Ensure the accuracy of test results, in line with European standards, en; 1995 "determination of formaldehyde emission from wood-based panels - Determination of formaldehyde emission by gas analysis". The product can be widely used in forestry research institutes, quality supervision and inspection departments, building materials production enterprises and other relevant units to test the formaldehyde emission of wood-based panels

technical parameters:

· chamber volume: 4017ml

· chamber temperature: 60 ℃ ± 0.5 ℃

· relative humidity: "3% RH

· air flow: 60L/h

p> p> p> p long neck bottle method for determination of formaldehyde emission +++++++++++++++++++++++

overview:

the basic principle of the instrument is: place a test sample with a certain exposure area in a 500ml container, place it statically at a temperature of 40 ℃, and after a period of time, formaldehyde is released from the test sample, so as to determine the formaldehyde emission of the sample. This method conforms to the European standard EN ； 1996 "determination of formaldehyde emission from wood-based panels - Determination of formaldehyde emission by long neck bottle method" is widely used in the testing of formaldehyde emission from wood-based panels by forestry research institutes, inspection and quarantine departments, building materials production enterprises and other relevant units
