Beautiful and generous.
Equipment characteristic
1. Adopt man-machine interface industrial touch screen and industrial computer PLC
2. Automatic control of the temperature and humidity of the test chamber, simple operation and high control accuracy.
3. Adopt high-precision temperature and humidity transmitter imported from France, indicating high accuracy, stable and reliable performance.
4. Modular design, integrated molding and assembly structure, simple operation, beautiful appearance.
5. Structural features: The box includes a working unit and an equipment unit. The studio is an independent space with humidity sensor, temperature sensor, circulating fan, heat exchanger, air inlet, air outlet, sampling port, etc. There is a sample holder in the work room, which is mainly used to place test samples. The equipment room consists of temperature water tank, dew point temperature water tank, water pump, air pump, flow meter, refrigeration compressor and water valve located on the right side of the studio.
6. Temperature and humidity controller: Siemens touch screen and PLC control module are used to achieve microcomputer automatic control, simple and intuitive interface, simple and reliable control.
Technical parameters

Temperature and humidity regulation mode: BT (H) C balance temperature regulation (humidity regulation) mode;
Operating temperature: 5ºC ~ 35ºC
3. Air tightness: test chamber relative to the external pressure: 10±5Pa, tightness: static leakage rate: 1kPa relative pressure, gas leakage ≤0.5% Cabin volume /min, air change times: 0.2 ~ 3 times /h, automatic servo control, stepless adjustable
4. Cabin size: cabin net capacity: 1m³
5. Air purification system: adjustable amount of external air: 0 ~ 3 m3/h; Intake temperature and humidity: 10ºC ~ 30ºC, 40-80%rh; Purification method: the fresh air is degraded at high temperature first, and then the adsorption oxidation membrane is filtered, and the temperature is carried out; Humidity adjustment, all the treated air into the cabin for exchange, to ensure the accuracy of the test.
6. Cabin material: Cabin inner wall: ≥1mm mirror stainless steel plate welding, on the outside of the inner wall with stainless steel profiles to strengthen the internal box, polishing and around the welding, no deformation treatment, edge, Angle are arc/oblique treatment, can be washed clean, no rubber and adhesives to interfere with the detection of materials, sealing materials and other devices in contact with the air in the test chamber, do not adsorb organic matter and formaldehyde. There should be no condensation or condensation in the test chamber.
7. Cabin air flow rate control system: to ensure the cabin sample surface air flow rate: 0.1 ~ 0.3m/s, adjustable
