• One container with sodium chloride solution
• Two wooden scrapers
• An insulated carrying case to hold all of the above and maintain a stable environment while performing calibration

The large container is used to create a stable environment. The small containers are used to hold the saturated salt solution. The saturated salt solutions generate well-defined humidities when they are confined to a contained environment. While the calibration process is very simple, it is important that you follow the steps carefully! A careless calibration could enter incorrect values into the unit and degrade its performance.
