This digital dissolved oxygen (DO) probe with built in temperature sensor has a 3.5mm jack connection for use with the Hanna Edge meters.
The ultra-thin Clark-type polarographic electrode is designed for measuring DO in aqueous solutions. It features a built-in microchip to store sensor type, serial number and calibration informaiton.
The sensor has a platinum cathode with a silver/silver chloride anode and integrated temperature sensor. The membrane cap is PTFE and easily replaceable.
The ultra-thin 12mm design allows for convenient measurement in narrow vessels including test tubes or wine bottles. With scre-on caps the PTFE meembranes are easy to replace for fast maintenance.
