Multi-function Sensor • Pre-installed sensors · The HI7698594 is supplied with pre-installed pH/ORP, EC/Turbidity and optical DO sensors • Quick sensor replacement · Sensor replacement is quick and easy with field replaceable, screw type connectors and are color coded for easy identification. These meters automatically recognize sensors. Multiparameter Probe and Sensors Easy sensor removal with hex key RFID tag Optical Dissolved Oxygen Smart Caps The optical dissolved oxygen sensor uses a smart cap that has an RFID tag that stores calibration coeÁcients unique to each cap. The RFID keeps track of the age of the cap and alerts the user when it should be replaced.
