A humidity control chamber is a kind of box that can be sealed for the purpose of making a controlled and humid testing environment. There are a lot of uses for humidity chambers, including pharmaceutical, scientific, electronic and forensic purposes. You can make different types and sizes of humidity chamber as long as you have the appropriate space for it. There should also be some attributes to the space such as a grounded outlet and a drain. To make it easier for you to follow the steps in making the chamber, it is advisable to use the right manual for the kind of humidity chamber that you are making.

    Step 1 – Inspecting New Equipment

    If the humidity chamber's pieces of equipment are new, always inspect them for damages that may have happened during the shipment.

    Step 2 – Looking for the Ideal Area

    A humidity chamber should be placed in an area that is well ventilated since it produces much heat when it is operating. Put it on a place that is not exposed to direct sunlight or air conditioning and heating vents. Make sure that you are putting it on a level surface as well. In addition, the area should also be dry and easy to clean.

    Step 3 – Ensuring Adequate Circulation

    To make sure that your humidity chamber will have sufficient circulation, make sure that a minimum of 2-inches separates it from the adjacent wall.

    Step 4 – Attaching the Exhaust Port

    If you are going to vent your humidity chamber, connect your external vent with the exhaust port. If you are not going to vent it, put the rubber stopper into the exhaust port.

    Step 5 – Attaching the Desiccator

    If your desiccators is not pre-installed or does not come internal to the humidity chamber, attach it to the humidity chamber by following the manufacturer’s instructions that come with it.

    Step 6 – Attaching the Pump

    The pump for the humidity chamber can be attached in the same way as the previous step.

    Step 7 – Attaching the Water Source

    Attach the water source for the humidity chamber. This could either be plumbed in by means of an external water line connection to the port for the water line or it could be a system for recirculating water. A manufacturer’s manual should come with a recirculation system for the water supply. Make sure that you follow it carefully. Fill the recirculation tank or pipe in water that has been demineralized.

    Step 8 – Connecting the Drain

    The drain pipe for the humidity chamber should be connected to a floor drain. If an external drain is not possible in your space, you can use a condensing pump instead.

    Step 9 – Feeding Testing Equipment Cords

    Find the cable hole on the humidity chamber and feed all cords that will be used for testing equipment through it. The hole must be sealed to prevent a leak but this can easily be done with a sealing putty.

    Step 10 – Plugging the Chamber In

    To power up your humidity chamber, you have to connect it to an outlet that has been grounded. For programming the right temperature and humidity, you can refer to the manual for them.
