The ultra-compact Piccolo2 is a fiber-optic oxygen meter integrated in a small USB stick housing based on the proven high-precision REDFLASH technology from PyroScience. The Piccolo2 is optimized for advanced applications of contactless sensors in closed set-ups with constant temperature. It features very low power consumption, contactless read-out of oxygen sensor spots through up to 20 mm thick windows, as well as real-time oxygen monitoring and microfluidic applications (lab-on-a-chip) with dispersible oxygen nanoprobes. Simply plug the Piccolo2 into a USB port of your Windows PC or tablet, connect the sensor of your choice and start calibrating and measuring with the comfortable logging software “Pyro Oxygen Logger”.
