Hanna Instruments HI-7698494-5 Optical DO Sensor - OPDO
Optical Dissolved Oxygen sensor for the HI-7698494 probe.
Optical luminescence quenching DO sensor for measuring percentage saturation and concentration of Dissolved Oxygen in water. Coloured green for easy identification, sensor replacement is quick and easy with replaceable, screw type connectors easily changed out in the field.
Optical Dissolved Oxygen Smart Caps - HI-764113-1
The optical dissolved oxygen sensor uses a smart cap that has an RFID tag that stores calibration coefficients unique to each cap. The RFID keeps track of the age of the cap and alerts the user when it should be replaced.
DO Sensor - Cleaning the Smart Cap:
- Use a mild detergent and a soft-bristled toothbrush to clean
- Rinse with water after cleaning and dry with a laboratory tissue
- Hydrate in purified water before use. Smart Caps require replacement on a yearly basis
Note: The first time a new DO Smart Cap is installed on a sensor and the sensor is installed in a probe and powered, the Cap start date will be registered in the Probe Status screen. After one year, a pop-up message will signal expiration.
