150L Humidity And Temperature Controlled Chamber For Electronic Devices

1. Introduction

The constant temperature and humidity test chamber is widely used in scientific research, research institutes, quality inspection institutes and other industries to do warm and humid heat tests of electronic and electrical products, materials, parts, equipment, etc., alternating heat test and constant temperature test, etc. Also could do high and low temperature routine tests, low temperature storage, in order to evaluate the performance of the sample under given environmental conditions.

It's widely used for industries of Electronic and Electric, Equipment and Instrument, Plastics & Rubber, Construction, Communication, Research and institute, Energy and Laboratories, etc.

2. High temperature limits of test chambers

There are many types of test rooms, but they all have high and low temperature limits. Let's take a look at the typical high temperature thresholds and why they exist. 

The test chamber typically has a wire heater made of a material called Nichrome. By placing a continuous heating bead, a greater amount of heat is produced. The result looks like a toaster inside. The fan circulates the air through the heater, so the indoor sample is not exposed to radiant heat. It is very easy to add a heater and increase the speed and / or upper limit of the chamber.

The SANWOOD chamber typically has a high temperature limit below 200 ° C. This is why a room of high temperature restrictions exist in the decomposition

Unit module standardization: Convenient installation, commissioning and subsequent maintenance are more convenient and cost-effective.

Environmental test standards establish criteria for a product’s, material’s, or component’s ability to withstand different environmental conditions for a period of time or over a projected lifetime.

Standards vary according to the industry, the type of item being tested, and its intended use. Examples of environmental or climatic conditions to which standard testing parameters apply include:

• Extremely high and low temperatures
• Rapid variations in temperature
• Humidity variations
• Salt spray and salt fog
• Vibrations
• High and low pressures

Environmental test standards apply to a wide variety of industry sectors, and some standards apply to more than one industry. These are some examples of specifications organized in alphabetical order:
