• 鈿涳笍聽聽Description:聽This is a聽generic moisture filter, otherwise known as a humidity filter, water-vapor filter, or air dryer filter. This tool is used聽to reduce the聽moisture content of an air or gas sample prior to聽analysis by a gas sensor. Removing聽moisture is聽important as most sensor technologies have cross-sensitivity to water vapor. These filters are commonly used聽in combustion line setups, breath analysis, or in humid sample environments (tanks, silos, caves, etc...).聽
• 馃摱聽 How does it work?聽Silica gel is a聽聽that can聽聽of its weight in water. Water molecules stick to silica bead surfaces through聽. Each bead has many tiny interconnected pores, resulting in a high surface area. These desiccant beads are dark blue and will change to a light pink when they have absorbed the maximum amount of moisture and need to be changed. Note: when they start to turn pink, they have usually about 40% life left. How soon you change them depends on聽personal preference and how important it is that you get no moisture in your air line.聽
• 馃懌聽聽Instructions: Connect the filter in line with the air supply line tubing.聽The filter is bi-directional so it does not matter which way it is connected. One end is the input and the other is the output to the sensor.
