What is Temperature and Humidity Chamber
Temperature and Humidity Chamber can simulate the effects that a variety range of temperature and humidity conditions have on a tested product or material.It helps in estimating potential success or failure of a product in the field.Is designed to simulate regular or specific environments in accordance with your requirements to test your product’s quality.
Uses of Temperature and Humidity Chamber
industries as food science, semiconductors, and military quality assurance.products as telecommunication equipment or photovoltaic solar panels that are exposed to outdoor temperature and humidity environment
What is Humidity Chamber
A Humidity Chamber is a tool for testing and analyzing the effect of different variations of humidity on components or products.
The data collected from the tests are then used by the engineers building the product to modify and improve it.
The testing can either be completed under static or a dynamic state, for different varieties of humidity chambers.
How Does A Humidity Chamber Work?
The main components of a humidity chamber perform two main functions, that is; to allow moisture and heat into the humidity chamber. Moisture can be introduced into the chamber by either spray or bath form, while heat is supplied into the chamber through heating coils or other heating elements.
Temperature and humidity are two factors that affect the stability of a product.
Manufacturers always have to test how humidity affects their products, as fluctuations in humidity may cause damage to the products
Artificial humidity is created through the following methods: steam generators, atomizers, and water baths
Recommended types of Humidity Chambers
Benchtop Humidity Chambers
These are cost-effective small-sized chambers for testing small products or parts, like cellphones, etc. Benchtop chambers sizes range from 0.89 cubic feet to 5.5 cubic feet.
Reach-in Humidity Chambers
Reach-in chambers have a vertical design to allow easy access during use. They come with wheels or casters for extra convenience.
Walk-in Chambers
Walk-in chambers are designed for walk-in, they are mostly used in automobile, battery production. The chambers have sophisticated steam and airflow systems to ensure the proper distribution of steam and air during use.
Drive-in Chambers
This is mainly used in the automobile industry. It allows manufacturers to test their vehicles under various conditions within the chamber.
Scientific Testing Chambers
They are used for testing specimens to determine what needs to be improved about the specimen. Scientific chambers are used in food science, pharmaceuticals, etc.
Parts Of A Humidity Chamber:
Sealing Material
The sealing material of a humidity chamber is built to withstand all sorts of temperature variations, including pressure, compression, etc. This keeps the chamber from getting affected by the products being tested which may damage the chamber or corrupt the test result.
Controllers
Humidity chambers have a proportional integral derivative (PID) controller. The controller automatically changes the control function of the chamber to fit the desired performance level.
Walls
Humidity chambers are double-walled and are either modular or welded to protect the chamber from contamination. Welded walls provide a better seal for the chamber to prevent outside contamination.
Temperature
Humidity chambers have heating coils or wires that serve as a direct source of temperature for the chamber. Large chambers have a more sophisticated heating system.
Humidity System
One of the ways to produce humidity in a test chamber is by heating water to produce steam. The chambers have vapor control to keep humidity production in check with international standards, it also has an overflow channel to prevent too much moisture retention.
Air Supply
The air supplier circulates humidified air within the chamber, using a fan, circulating wheel, or circulating motor.
Materials
Most chambers are built with welded steel frames on the outside and stainless steel on the inside. The materials are also treated properly to ensure they are of the highest quality.
Doors
The doors are double-walled and fitted with heavy hinges to keep the chamber tightly sealed when closed.
Uses of humidity chamber
-Pharmaceutical laboratories
-medicine
-Food Labs
-Cosmetics labs
-Laboratories that grow seeds, plants and insects
What to consider
Factors like space, product size, cost, and so on should be considered before choosing a test chamber
They include:
Space
The test chamber a manufacturer gets must be able to fit perfectly in their available space. Producers of test chambers always work with their clients to ensure they buy a test chamber that fits the client's needs and available space.
Temperature
It is important to know if the chamber can reach the required temperature for your products. Most chambers can reach 200°C, but this may not be enough temperature in certain industries.
Water Supply
Water is needed to create humidity in a test chamber, the size of the chamber determines how much water it uses. The chamber must be connected to an adequate water source and have a reliable drainage system.
Time
It is important to ask about the processing speed of the chamber to know how long it takes to process information and completely collect the data. Chambers with long ramp-up times are not suitable for testing some product types, as delay may taint the generated data.
Relative Humidity
The RH of most humidity chambers is between 20% to 90%. The type of products to be tested and the required data determine how much RH is needed.
Controller
It is important to consider the controller of the chamber before buying one. There are different types of controllers, but the best controllers have microprocessors and are either LED or LCD.
Types
The most common consideration could be whether it's a vertical test chamber or benchtop type. Other factors to consider are how the door opens, if the seams are welded, etc.
Large test chambers are usually built according to the client's request.
