Overview

The purpose of the constant temperature and humidity test chamber is to provide a programmable testing environment and conditions for the development, production, and inspection of products, including heat resistance, cold resistance, high temperature resistance, and moisture resistance

Product Details


The purpose of the constant temperature and humidity testing chamber is:
The programmable constant temperature and humidity test chamber provides testing environments and conditions for heat resistance, cold resistance, high temperature resistance, and moisture resistance in various stages of product development, production, and inspection. It can accurately simulate complex natural environments such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, and alternating high and low temperature and humidity. It is suitable for product reliability testing in various industries such as plastics, electronics, electrical appliances, food, clothing, vehicles, metals, chemistry, building materials, scientific research institutions, and universities.
The main features of the constant temperature and humidity testing chamber are:
1. Perfect styling design: curved shape and surface spray treatment, high-quality appearance, and the use of flat non reactive handles. The programmable constant temperature and humidity machine is easy to operate, safe and reliable
2. Bright and wide field of view large observation window: using three-layer vacuum coating window and Philips energy-saving fluorescent lamp, no need for wiper defogging, maintaining clear observation effect in the programmable constant temperature and humidity chamber, and allowing observation of the condition of the test sample in the programmable constant temperature and humidity test chamber at any time.
3. Separation of humidification system pipeline and control circuit: The humidification system pipeline in the constant temperature and humidity machine is separated from the power supply, controller, and circuit board, which can avoid the programmable constant temperature and humidity test box from affecting the circuit due to pipeline leakage and improve safety.
4. Advanced and reliable refrigeration and control system: Original imported European and American fully enclosed compressors, imported environmentally friendly refrigerants, and world-renowned brand refrigeration components make the operation of the programmable constant temperature and humidity test chamber simple and easy to learn.

Difference between constant temperature and humidity test chamber and high and low temperature test chamber:
The programmable constant temperature and humidity test chamber provides testing environments and conditions for heat resistance, cold resistance, high temperature resistance, and moisture resistance in various stages of product development, production, and inspection. It can accurately simulate complex natural environments such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, and alternating high and low temperature and humidity. The high and low temperature test chamber can provide environments such as high and low temperatures. It can also be simply considered that the programmable constant temperature and humidity test chamber has added humidity control function on the basis of the high and low temperature chambers, and the humidity range is generally between 20-98%. If the product is sensitive to humidity, it is necessary to purchase a programmable constant temperature and humidity test chamber. If the impact of humidity on product performance can be almost negligible, then simply purchase a high and low temperature test chamber. Just tell us your product, the maximum temperature and humidity points for testing, and we can directly recommend our most cost-effective and suitable one based on the data from your peers!
