Constant Temperature And Humidity Test Chamber
The constant temperature and humidity test chamber is also called a constant temperature and humidity testing machine, a constant temperature machine, or a constant temperature and humidity chamber. It can test the performance of materials in various environments. It can test various materials for heat resistance, cold resistance, and heat resistance. The constant temperature and humidity test chamber is dry and moisture-resistant. It is suitable for quality testing of electronics, electrical appliances, and other products.
The panel basically displays the temperature (humidity) control display, over-temperature protection setting device, emergency switch, operation indicator light, and fault indicator light. We can customize different test standards and special temperature and humidity test chamber sizes.

Constant Temperature And Humidity Test Chamber Features
1. Unique design of the chamber within the wind circulation structure to ensure uniformity within the box within ± 2 ℃ under the test case conditions.
2. New PWM cold control technology to achieve low-temperature energy-saving operation. In low-temperature working conditions, the heater does not participate in the work through the PWM technology to control the refrigeration unit refrigerant flow and flow, the cooling pipe, cold bypass pipe, and hot bypass pipe three-way flow adjustment. To achieve the automatic constant temperature of the studio. This mode can achieve a 40% reduction in energy consumption at low temperatures.
3. Temperature synchronous slope control (IEC68-2-56, 68-2-30), no dripping, and no condensation.
4. The refrigeration room is fully sealed and soundproofed to reduce machine noise, box resonance, and machine noise control within 75.
5. The protection system consists of a dehumidifying evaporator, which prevents condensation from forming on the specimens as they heat up after tests at low temperatures.
