Constant temperature and humidity test chamber and high and low temperature test chamber in the function and application of significant differences, the following is a specific comparison of the two:
Constant temperature and humidity test chamber
Constant temperature and humidity test chamber is a kind of environmental simulation equipment that can control temperature and humidity at the same time. Can simulate a variety of complex temperature and humidity environment, to meet the testing needs of a variety of products, with high precision, high stability and programmable control and other characteristics.
Mainly used to test products or materials in a variety of temperature and humidity combination of conditions under the performance of performance, such as heat resistance, cold resistance, dry resistance, moisture resistance and other characteristics. Its temperature range is usually -70℃150℃ (or -40℃150℃), and the humidity range is 20%98%RH (or 30%98%RH).
The structure of constant temperature and humidity test chamber usually consists of a temperature regulation (heating, cooling) system, humidification system, control system, air circulation system, and sensor system. It is through the control system to monitor the temperature and humidity in the chamber in real-time, and automatically adjust the working status of the temperature and humidity adjustment system to achieve accurate temperature and humidity control. The humidification system usually adopts ultrasonic humidification or steam humidification, while the dehumidification system may adopt condensation dehumidification or desiccant adsorption dehumidification.
Widely used in electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other fields of product quality testing.
High and low temperature tester
High and low temperature test chamber is a kind of equipment focusing on simulating high and low temperature environment. Focusing on temperature control, it has the characteristics of wide temperature range, fast rate of temperature rise and fall, and high precision of temperature control.
It is mainly used to test the performance of products or materials under high and low temperature conditions, such as the durability and reliability of electronic components, circuit boards, automotive parts, etc. under extreme temperatures. Its temperature range is usually up to -70℃ or lower, but does not have humidity control function.
The structure of high and low temperature tester is mainly composed of refrigeration system, heating system, control system and temperature sensor.
It accurately adjusts the working status of the refrigeration and heating system through the control system to achieve the temperature rise and fall inside the chamber. The temperature sensor monitors the temperature inside the chamber in real time and feeds back to the control system to ensure the stability and accuracy of the temperature.
It is mainly used to test the performance of products or materials under high and low temperature conditions, such as the durability test of electronic components, circuit boards, automotive parts and so on.
