Humidity calculator is used for measuring humidity. Humidity are measured indirectly with dry and wet-bulb thermometers. The dry-bulb is an ordinary mercury-in-glass thermometer and measures the air temperature. It shows the inter-relationship of air temperature and moisture content with dew point and wet-bulb temperature as measured by a psychometric thermometer.

Humidity chambers are used to ensure the reliability of industrial products, especially electronic & metal items, through prolonged exposure to temperature & humidity parameters. They provide heating and/or cooling and often include an analog meter, digital readout or video display with test results. Some chambers subject samples, components or products to extreme temperatures, thermal cycling or extreme humidity to find how the components cope up with the extreme environment. In humidity chamber we can obtain a particular temperature and a particular humidity by fixing wet & dry temperature to a particular point. All chambers will have a standard values which gives the details of setting wet & dry temperatures to get the needed humidity & temperature. Performance specifications for chambers include temperature range, temperature control accuracy, humidity range, humidity control accuracy and chamber capacity. Temperature range and humidity range are full-scale values. Temperature range accuracy is measured in degrees or as a percentage of a full-scale output or reading. Humidity control accuracy is expressed as a percentage.

Humidity generator is an automated, portable, self-contained bench top instrument, which easily integrates with other laboratory instruments to supply a specified constant flow rate of a specific relative humidity. It calibrates a wide range of humidity measurement instruments and generates relative humidity with high accuracy.

Humidity Indicators are used for relative humidity inside rigid containers, electronic enclosures, optical cavities and flexible moisture-vapor-proof bags. It is used in conjunction with a static type desiccator. Mounting options include thread mounting into enclosure, panel bushing or crimp nut. This indicators are used with desiccant and breather valves to provide a complete environmental control system. Breather Valves are also known as pressure relief valves.
