Humidity Test Chambers

We all know that product quality is one of the major concerns for manufacturers that can make or destroy their reputation in the market. If you are the one that needs to assess the physical properties of your product to improve its quality, then we suggest you go with Presto humidity chambers. Presto’s Humidity Test chambers can aid reliable testing by subjecting various products to environmental extremes like humidity, temperature. Presto’s Humidity/Conditioning Chamber is able to provide quick temperature change rates and humidity conditions required for analyzing the effects of ecological changes on the product. The product helps to judge the reliability and quality of various products like plastics, rubbers, electronic goods, automobile parts, and semiconductor devices, etc. The procedure of the equipment relies on the principle of accelerated environmental testing.

Presto’s conditioning test chambers are ideally designed with sophisticated technology to maintain designated temperature and humidity at set points controllable by the user at the front control panel. The Presto humidity chamber has been equipped with a highly insulated glass wool Ergonomic that ensures the lowest heat loss ratio. This testing machine has completely digital controls. Air is constantly circulated throughout the chamber which can be easily monitored from the transparent glass for comparison to set points and can be treated if necessary. Heating is done by the electric heaters that can turn on and turn off for temperature control.

The main purpose of the humidity chamber is to assess different properties of the product under particular temperatures and humidity levels. This is because the temperature conditions play a very important role in affecting the product quality. You can effectively make use of this testing machine for different industries like textile, fabric, metal, etc. The temperature and humidity are two parameters that will lead to failures of the product. Thus, you need to qualify these factors so that there will be no effect of the temperature and humidity on the product. The humidity/Conditioning chamber maintains testing samples at a particular temperature and humidity level. The environmental conditions play a crucial role in affecting both the physical and chemical properties of materials. Conditioning Chamber is used for textile/ fabric materials after process completion; the main task of this chamber is to remove the moisture level in the sample.

This methodology follows a proven technique that maintaining a constant setpoint and temperature will produce a very constant relative humidity. The system does not distinguish between humidifying and dehumidifying; it is always setting a set point and reheating. If the conditioned air has a higher moisture content than the setpoint, excess moisture condenses out and dehumidifies the control air. Conversely, if the conditioned air has lower moisture content than the setpoint, moisture evaporates and humidifies the control air. The temperature of the water is automatically adjusted by the feedback from a high-grade RH sensor in the controlled space. If the setpoint is lower than the actual condition, the temperature of the water will gradually decrease until the RH set point is achieved. On the other hand, when the relative humidity setpoint is above the actual condition, the water temperature is incrementally increased until the RH set point is achieved.

When the testing specimen like metal will be used in environmental conditions, then it may come in contact with various environmental factors. The temperature and humidity are among the top of them. Thus, you need to make use of proper testing equipment like Presto humidity chamber, to assess the physical properties of the specimen. By evaluating the physical properties of the specimen, you can easily produce high-quality material for your customers. To operate this testing instrument, you need to first install this testing machine accurately. After that, you can turn the machine ON. If the water-level low LED” glows on the control panel then, it is required to fill water in the water reservoir present at the backside of the chamber.

Maintain the water of the machine by connecting the DM water line with the inlet port provided on the backside of the machine to fill the water. The side inlet connected to the water reservoir should always be ON. Connectivity of the water should not be stopped. It will auto-refill the water when required and automatically stop when the tank is filled completely. The side inlet connected to the water reservoir should always be ON. This will help to create the required level of humidity inside the chamber.

Once you follow all the steps, then you need to prepare the specimen. After that, you can operate the testing machine. When the temperature in the digital read-out is more than the SET temperature, the cooling process automatically gets started ON, to reach the SET point. With the help of a manual preset timer button, the user can set the time for how long the machine needs to be operated according to his/her choice.
