150L Temperature Humidity Test 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
