Calibration and standardization make sure tools measure things right. It's like checking a ruler to ensure it measures inches or centimeters correctly. For tools that keep an eye on the environment, like air or water testers, this is super important. EnvMart steps in to adjust and set these environmental meters and sensors, so they give accurate results. They also work on making different tools match up or "standardize" them, so everyone's measurements are the same. This service is a big deal for science and safety.
