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.

High Quality Hardware

It adopts oil-free tetrafluoro-diaphragm bipolar air pump with high precision, positive and negative pressure output, and zero emission from the air circuit of the air pump. Provide a pure air source for the climate chamber.

The constant temperature system and dry gas tower refrigeration use high-power fluorine-free zero-emission refrigeration

compressors, which have fast refrigeration speed and noise value less than 60dB.

Accurate and Stable

Humidity control: Innovatively set up an independent humidity mixing balance system, which separates water and gas in

dehumidification and humidification, making the experimental data more accurate. Unique computerized intelligent mixing control of dry and wet gas, the humidity control accuracy can reach within 0.5%. (The first ten minutes after the first arrival is within 2%)

Quick balance: temperature and humidity quickly balance, under normal circumstances, the set value can be reached within 10-30 minutes. The balance time is more than five times faster than the dew point method, and the purity of the air entering the box is greatly improved.

The metal platinum resistance temperature sensor measures the temperature in the box with good accuracy, 0.01 degrees, and long service life.

High Security

The system is equipped with high and low temperature over-limit alarms, and various water level and water limit alarms of the constant humidity system to ensure the safe operation of the equipment. Humanized water level simulation observation interface.

The water level status is clear at a glance.

Smart and Efficient

The frequency converter system is used to accurately control the wind speed in the cabinet and the corresponding air volume and speed display. Realize adjustment control.

Set the temperature, humidity, humidification temperature, working time, gas flow and other parameters of the climate chamber through the touch screen, automatically calculate and automatically control the humidification temperature, and display temperature, humidity, time and other data in real time. Store and export data such as temperature, humidity, and time. Historical fault query, historical data playback function. Various functions such as power-on appointment booking for permission setting.
