Is DO Sensor and pH sensor works on saltwater?

Hello! I am currently pursuing my thesis. My topic involves monitoring system in saltwater farms. With this, I want to ask if the available DFRobot Gravity: Analog pH sensor and DFRobot Gravity: Analog Dissolved Oxygen sensor is applicable in saltwater? If yes, are there any effects on my measured values when using the sensors in saltwater? thank you guys!

You can do some experiments with saltwater such as ploting.

These sensors are not calibrated in saltwater, and the parameters of the algorithm are not sutiable for such scenario.  The sensor readings are meaningless.
