Prior to installation, store the sensor in the factory supplied container.
Once installed on the sonde, the Temperature Sensor and Conductivity Sensor can be stored wet or dry
depending on the sensor configuration of the sonde. For the best accuracy over instrument life, keep the
conductivity cell submersed in water for 24-48 hours prior to calibration and deployment.
The optical windows should be clear of foreign material. To clear material gently rub the sensing windows
using clean water and a soft cloth or swab. Do not use solvents on the sensor.

Prior to installation, store the sensor in the factory supplied container. Once installed on the sonde, the
turbidity sensor can be stored wet or dry depending on the sensor configuration of the sonde.
Wiper bristles need to be replaced based on site conditions. In-Situ recommends replacing bristles at least
every 12 months or when visibly bent, damaged, or fouled.
