Overview

Constant Temperature and Humidity Test Chamber Programmable Constant Temperature and Humidity Testing Machine

Product Details

The technical parameters of the constant temperature and humidity test chamber are suitable for testing and detecting temperature and humidity changes in products such as textiles and clothing, electronics and electrical engineering, food, plastic and rubber, automotive manufacturing, lighting fixtures, chemicals, building materials, chemical reactions, etc. The high and low temperature alternating humidity testing machine has a large temperature and humidity control range and can provide tests such as constant high temperature test, high temperature and high humidity test, constant low temperature test, constant humidity and heat test chamber, and high and low temperature humidity and heat combination cycle.

Detailed Introduction to Technical Parameters and Equipment of Constant Temperature and Humidity Test Chamber

Humidifier dry burning protection, independent overheating protection, water shortage protection, compressor overload, overheating, overcurrent protection, refrigerant high voltage protection switch, overcurrent circuit breaker, leakage protection and other protective devices.

1. All temperature change rate clauses refer to the average rate of change of air throughout the entire process, rather than the rate of change of product temperature.

2. The rate of temperature change will vary depending on the specimen load, specimen material structure, and temperature range.

3. Cooling water temperature (ensuring cooling performance): 10-28 ° C, water pressure 0.1-0.3Mpa.

4. The external dimensions of the above products do not include protruding parts, and the product dimensions can be customized according to customer requirements.

5. The above technical parameters were measured at room temperature of 25 ℃± 6 ℃ under no-load conditions.

Product characteristics of constant temperature and humidity testing machine

1) The brand new circular arc design has a high-quality and beautiful appearance, and adopts a flat non reactive handle for easy operation.

2) The original imported multi-functional and highly expandable dedicated touch temperature controller is easy to operate and learn, stable and reliable for high and low temperature and dual low temperature tests.

3) The Balanced Temperature and Humidity Control System (BTHC) controls SSR in a P.I.D. manner, ensuring that the heating and humidification capacity of the system is equal to the heat and humidity loss, thus enabling long-term stable use.

4) New modeling design, high quality appearance, and systematic design and manufacturing based on the essence of advanced technology in Japan and West Germany.

5) Adopting full capillary tube and automatic load capacity adjustment system technology, it is more stable and reliable than the expansion system, with temperature and humidity control, fast, stable, and even temperature rise and fall speed, saving valuable time for users.

Architecture composition of constant temperature and humidity test chamber system:

A constant humidity and temperature chamber refers to a test chamber that can simultaneously apply temperature and humidity stress. With the need for industrial product development in China, in recent years, China has introduced a large number of testing systems from abroad, which have played an important role in the development and standardization of Chinese industrial products. However, due to their complexity, many problems have arisen during the operation of the testing chamber, and these problems cannot be solved in a timely manner, greatly extending the testing cycle and affecting the development of products. The reason for these phenomena is a lack of understanding of the working principle of comprehensive experiments. For this purpose, we have provided a brief explanation of the basic working principle of the test box and introduced how to analyze and diagnose faults in the comprehensive test box testing equipment.

The constant temperature and humidity test chamber consists of a refrigeration system, a heating system, a control system, a temperature system, an air circulation system, and a sensor system. The above systems belong to two major aspects: electrical and mechanical refrigeration.
