iqualitrol temperature humidity test chamber is used to test various types of materials for their tolerances of heat, cold, dry, humidity. It is applied for quality inspection for all types of electronic products, electric appliance, and products from battery, communication, instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries.
Temperature and humidity testing help to determine the behavior of the components in severe test conditions and environments that involve fluctuating environment, high temperature, and different relative humidity. The tests can be done with constant temperature and humidity in a static state and can be done in a dynamic state where the moisture is used to induce a failure of the components or materials.
How to Choose a iqualitrol Climatic Test Chamber Size?
Choosing a correct chamber size depends on the application and your available floor space. The iqualitrol suggested ratio is about 1:3 between product volume and the working volume of the chamber.
⅓ product to ⅔ empty space around the product ensures adequate airflow to the test sample and makes sure your test is conducted properly. Items that allow for airflow (such as a computer chassis with plenty of air vents) can take up a larger percentage of the test volume.
Externally, consider that these machines create a lot of heat, and with test cycling up and down the temperature spectrum, the chambers themselves require good air circulation. Some units will require up to three feet (or more) of clearance in all directions to work properly.
Depending on whether the test product is a live load, a larger chamber may be needed to dissipate heat produced by the test subject, adversely affecting the chamber’s pull down times or humidity system.
Sand, dust, and high altitude chambers do not need a 1:3 ratio of product volume and empty space. The air speed inside the chamber is already very high for the products and makes a 1:3 ratio unnecessary.
These chambers should be just slightly bigger than your test product.
1, Chamber exterior material is stainless steel with environmentally baking paint resists corrosion and provides impact resistance. Interior material is SUS304# stainless steel with excellent heat resistance and easy to clean.
2, Touch screen controller is designed to save chamber programming and setup time with temperature limit and alarm to protect your product.
3, Safety relay connection is provided to protect your device under test by removing power to it when the chamber is not running.
4, RS-232 communications is for computer connection, programming can be set on computer by software, monitor testing process and automatically execute power on/off functions.
5, Fog-free viewing window and interior light makes viewing workspace freely and observe the test under best conditions.
6, Adjustable product shelf slides out for easier product access. Shelf design is non-tipping and supports large product loads.
7, Left side of chamber with diameter 50mm (support customized) cable port for power-on test.
8, Optional electronic humidity sensor is used on all test chambers for accuracy and minimal maintenance.
1, Cable Port: Size of cable port is available for 100mm, standard is 50mm;
2, Water purifier RO 80: Continuously provide purified water for humidifying heater and wet-bulb
3, Dehumidifier: The rotation regenerating dehumidifier M-120 ensures precise control of low humidity (10C, 15%RH) for electrostatic reliability tests.
4, Defrosting Device: The chamber automatically detects and melts the frost on the evaporator when operating below 0deg in order to allow continuous operation
5, Electronic humidity sensor: Precision Humidity Sensor with stainless steel protection tube
