Video Transcript

In this video, we will cover optical sensor maintenance and storage. The Optical Dissolved Oxygen sensor is covered in a different video. These instructions apply to Turbidity, Total Algae, Rhodamine, fDOM, and NitraLED. These sensors are very low maintenance. Just make sure the sensing window is kept clean and free of scratches.

Periodically inspect the optical surface at the tip of the sensor, and wipe it clean with a non-abrasive, lint-free cloth like a Kimwipe. When installing or removing a sensor, be careful not to damage the sensing lens.

As with all sensors and components that have a wet-mate connector, keep the connector free of debris by wiping it clean, and lubricate the rubber and o-rings with Krytox grease.

For short-term storage, the sensors can be left in the sonde between uses. They do not need to be kept moist, but they can be kept installed in the sonde in a calibration cup with water if you have other sensors installed that need to be kept moist, such as pH or DO.

For long-term storage, you can either keep the sensors in the sonde or remove them. They can be stored dry in the air, and you may choose to cover the sensor tip with the shipping cap to protect it from damage.
