What is a constant temperature and humidity test chamber?

Constant temperature and humidity test chamber is also called constant temperature and humidity test machine or constant temperature and humidity test chamber. It is mainly used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dryness resistance and moisture resistance of various materials. It is used for quality inspection in industries and fields such as electronics, electrical appliances, food, medical treatment, education, and scientific research. Constant temperature and humidity test chamber can detect parameters and performance after high temperature, low temperature, alternating humidity and heat or constant test temperature environment changes.

What are the uses of constant temperature and humidity test chambers?

Constant temperature and humidity test chambers are widely used, mainly for the adaptability test of electronic components, plastic materials, paper printing, metals, original devices and other materials in high temperature, low temperature, hot and humid environments during storage, transportation and use. Constant temperature and humidity test chambers are used to perform environmental simulation tests on the physical and other related characteristics of products under low temperature, high temperature, high temperature and high humidity conditions according to certain requirements or user-defined requirements. After the test, the performance of the product is judged by detection to see if it can still meet the predetermined requirements, so as to provide product design, improvement, identification and factory inspection.

Common faults and repair steps of constant temperature and humidity chambers

Including constant temperature and humidity test chambers, walk-in constant temperature and humidity chambers, low temperature constant temperature and humidity test chambers, etc. Some faults of these products are similar.

1. The heating wire cannot be heated in the box and is burned out: After inspection, when the heating wire is burned out, the heating wire of the same power can be replaced according to the circuit diagram.
2. The circuit knot is loose or the soldering is off and the circuit is broken: Use an ammeter to check and find the loose part, tighten the screws or weld.
3. The indicator light is not on: It may be due to loose joints, broken wires or burnt bulbs. You can connect the line firmly or replace the bulbs of the same specifications.
4. The constant temperature is unstable, or sparks are emitted from the relay point: The relay point may be damp and rusted, and the contact is poor. Sandpaper can be used to wipe off the rust on the relay point. During maintenance, it must be carried out under the power cut off, and it must not be operated with power on. If the instrument has a major fault and cannot be repaired by yourself, you need to ask a professional or send it to a specialized agency for maintenance. Do not disassemble it randomly to avoid damage.
