Generally, a constant temperature and humidity testing chamber can provide a temperature range that spans from very low temperatures, such as -70 degrees Celsius (-94 degrees Fahrenheit), to high temperatures, such as +150 degrees Celsius (+302 degrees Fahrenheit). However, it is important to note that not all chambers offer such an extensive range, and some may have more limited temperature capabilities.

The humidity range of these chambers can also vary, typically ranging from around 10% relative humidity (RH) to 95% RH or higher. Again, the specific range will depend on the model and manufacturer.

It is worth mentioning that the temperature and humidity range of a constant temperature and humidity testing chamber are interrelated. As the temperature increases, the chamber's ability to maintain high humidity may decrease, and vice versa. Therefore, it is essential to consider the specific requirements of the testing application and select a chamber that can provide the desired temperature and humidity conditions within the required range.

Additionally, some advanced constant temperature and humidity testing chambers offer precise and programmable temperature and humidity control, allowing users to set specific parameters and create customized testing conditions. These chambers often come equipped with sensors, controllers, and user-friendly interfaces to monitor and adjust the temperature and humidity levels accurately.

Overall, the temperature range of a constant temperature and humidity testing chamber can vary, but it typically covers a wide spectrum of temperatures, from extremely low to high, while providing controlled humidity levels for various testing applications.

The temperature range of constant temperature and humidity testing chambers can vary depending on the specific model and manufacturer. Here are some examples:

Amade-Tech offers constant temperature and humidity chambers that can simulate temperatures ranging from extremely low values at -70℃ (-94℉) and 20% relative humidity (R.H) to exceeding high values at 150℃ (302℉) and 98% R.H^1.

Skyline Temperature Humidity Chambers have a temperature range of -20°C to +150°C and a humidity range of maximum 20% to 98% R.H^2.

Labtech's constant temperature and humidity chambers can meet a wide range of temperatures, from high temperatures up to +150℃ (+180℃, +200℃) to low temperatures down to -40℃ (-60℃, -70℃, -80℃)^3.

It is important to note that these are just a few examples, and the temperature range can vary among different manufacturers and models. When selecting a constant temperature and humidity testing chamber, it is crucial to consider the specific temperature requirements of your testing application and choose a chamber that can provide the desired temperature range.
