Walk in chamber comes in a variety of sizes, from a small box that fits on the bench top to a room-sized chamber for large objects or for testing large batches of product simultaneously. Temperature ranges from -60° C to 150° C and relative humidity ranges between 20% and 90% are available. A temperature humidity walk in chamber can also be used when constant climate conditions (temperature and/or humidity) are needed for product testing.

Walk in test chamber simulates the effects that a range of temperature and humidity conditions have on a product or material, for example telecommunications equipment or photovoltaic solar panels that are exposed to outdoor temperature and humidity conditions.
