Portable samplers are devices used to collect samples of air, water, soil, or other materials in various environments. They are designed for easy transport and can be used in remote locations or during field studies. These samplers help researchers and environmental scientists gather data without needing a fixed laboratory setup. These tools come in various forms, such as air samplers, water samplers, and soil samplers, each tailored for specific sampling needs. Portable samplers are essential for monitoring pollution, assessing environmental health, and conducting scientific research in diverse settings, from urban areas to natural habitats.
