1、 Product Overview
This product is suitable for the determination of formaldehyde emissions from various indoor decoration materials such as artificial boards, composite wooden floors, carpets, carpet liners, and carpet adhesives. It can also be used for constant temperature and humidity balance treatment of wood or artificial boards, as well as for the detection of volatile harmful gases in other building materials. This product can simulate indoor climate environment to the maximum extent, making the detection results more realistic.

4、 Product Features
Use large-area heat exchangers，inside the cabinThe heat transfer temperature difference is small, the heat exchange is uniform, the temperature is stable, and there will be no condensation.
microcomputerPIDAdjustment, fast response speed, high control accuracy, humidity balance of about half an hour, far faster than dew point method, shortening the experimental period.
The moisture adopts the company's unique low-temperature evaporation technology, which has no resistance, no temperature difference, and gentle humidification without condensation.
Low background concentration design, all components such as sealing materials and air displacement pipelines are non releasingformaldehydeClean materials such as stainless steel, copper, tetrafluoroethylene, etc.
Energy saving design commonly uses frequency converters and thyristors to regulate loads and achieve lower operating power.
Through precision filtersWater washing deviceThe processed gas supply is very clean and can isolate external pollution.
Microcomputer intelligent control, automatic temperature control, automatic humidity control, automatic alarm, automatic recording, one key switch, full process monitoring.
Gas supply components、The filtering components and humidification components are all built into the control cabinet, which saves space, has low noise, and is simple and beautiful.
