CHINA standard constant temperature and humidity laboratory Test Chamber, paint panel -20~150 ℃/50L

use

This constant temperature and humidity environment Test Chamber can simulate various temperature and humidity environments, and is mainly used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. It is suitable for quality inspection of products such as electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical care, and aerospace.

Control method: Adopt balanced temperature and humidity control system (BTHC), the sensing system transmits the actual data in the Test Chamber to the controller, and the controller controls the SSR, multi-stage intelligent output, and balances the output power of the temperature and humidity system to ensure that the temperature and humidity in the Test Chamber The temperature and humidity are fully stable, and have energy-saving functions, which can reduce the power consumption of the instrument to a greater extent and ensure long-term accurate and stable operation of the instrument.

3. The refrigerating cycle system adopts a compressor: a fully enclosed compressor imported from Japan "Sanyo" brand (purchased by a French Taikang compressor), and all components are imported from Japan, France, the United States, Italy and other places of origin. The refrigerant adopts American environmental protection refrigerant (R23A, R404A).

4. There is a reserved test hole with a diameter of 50mm on the left side of the test box.

5. Equipped with full-automatic, high-precision system loop, any part action, PLC lock processing, all adopt PID automatic calculation control, the temperature of the whole area has high precision and high stability.

6. Specially designed air circulation system and sensor system, sensor detection and control at the air outlet and return air outlet to ensure the uniformity of temperature in the Test Chamber and avoid any dead angle.

7. It adopts enlarged observation window and 4-layer hollow tempered glass, which has a wider field of view.

8. The instrument has a comprehensive protection system, power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over-temperature protection, alarm sound prompts, etc. When any abnormal situation occurs, the fault will be automatically displayed on the screen immediately Point and reason and stop automatically.

Temperature and humidity control range curve

Heating system

Multi-section heating tubes are used to cooperate with PID modules to ensure temperature stability; segmental heating is fully energy-saving.

The heating tube adopts high temperature resistant and corrosion resistant alloy tube to prolong the service life

humidification system

The circular split type humidifier avoids the phenomenon of freezing during the low temperature test of the sink type humidifier.

The humidification tube is made of special alloy, which can be dry-burned for more than 1 hour when the instrument fails and lacks water. With the high temperature alarm module, the service life of the humidification system is effectively extended. Built-in Water Tank, drawer type Water Tank, convenient and beautiful.

With water circulation system, saving 40% of water.

It has a water quality filtration system to avoid blockage of the humidification system as much as possible and reduce cleaning frequency.

Air circulation system

1. High resistance air circulation motor

2. Multi-wing fan blade

3. Specially designed fan forced air circulation system

Cooling System

Compressor: Original imported Japanese "Sanyo" brand fully enclosed compressor (French Taikang compressor to buy)

Condenser: finned multi-stage condenser with integral forced cooling fan

Evaporator: Fin-type multi-stage automatic load capacity adjustment evaporator, with energy-saving regulating valve, to achieve forced refrigeration, constant temperature refrigeration section control

Refrigerant: The United States imports new environmentally friendly refrigerants R404A, R23A to achieve zero pollution to the environment

Freezing Oil: American Ice Bear Freezing Oil

Drying filter: Italy Castel drying filter

Solenoid valve: Japanese Lugong solenoid valve

Copper pipes: The pipes used in the refrigeration system are all made of imported red copper material, which has the advantage of good flexibility and is not easy to break, and has a better shock-absorbing effect on the long-term vibration characteristics of the refrigeration system.
