China 1m3 Formaldehyde Emission Test Chamber

Product characteristics:
This product is the first time that R&D institutes put forward the tracking control technology of detection environment to replace the inaccurate/accurate form technology. The precision is one order of magnitude higher than that of foreign advanced technology products, and it is in an advantageous position in the world. This product has been used in the National Wood-based Panel Quality Supervision and Inspection Center, Customs, import and Export Quarantine Inspection Bureau, and its technical performance indicators meet the national standards.
-Formaldehyde emission limits in wood-based panels and their products for interior decoration(GB 18580-2001)and National Environmental Marking Industry Standard Technical Requirements for Environmental Marking Products Artificial Wood Board(HJBZ 37-1999).
Features:
1. Robust tracking control: Through computer program precise/accurate control, adjust temperature and humidity, control accuracy is high.
2. Data output: The temperature and humidity historical records can be consulted and printed by computer.
3. Instrument digital display: The real temperature and humidity data in the box can be read directly by the instrument.
4. Advanced heat exchanger technology: high heat transfer efficiency, low temperature gradient.
5. Cooling and heating water tank: temperature control is stable.
6. Dew/Point Temperature Adjustment of Air Humidity: The air humidity entering the box is controlled by robust tracking. The humidity is uniform and does not dew at the corresponding temperature.
7. Advanced humidity, temperature and humidity sensor: The sensor has high precision and stable performance.
8. Oil-free magnetic pump: The water circulation system adopts the American oil-free magnetic pump, and the wet air does not affect the gas detection in the tank.
9. Superior refrigerators: imported refrigerators, stable operation, long service life.
10. Low water level protection: constant temperature and dew/point water tank have low water level alarm.
11. Stainless steel inner box: the inner surface is smooth and does not adsorb formaldehyde.
12. Component combined structure: Climate box is a component combined structure, which can be successfully pushed into the room with ordinary single door.
