Visibility and present weather sensors are in many meteorological applications worldwide. They are often used as a part of nationwide weather networks or as components in aviation and road weather monitoring systems. All of these systems require the sensors to be optimized for accurate and repeatable measurements.

Many of these applications are safety-critical and reliable data is essential for the correct operation of their modeling or decision-making process. Therefore, each visibility and present weather sensor must be regularly checked and re-calibrated against an independently verified testing standard to ensure their accuracy.

MicroStep-MIS provides a complete solution for calibration of your visibility sensors consisting of the visibility calibration kit, portable and battery-operated field standard with a data logger, and the calibration software IMS4 CalibLab.
