Multiple conductivity sensors on one Raspberry

Hello all, this is my first time on this forum, so please let me know if this is posted in the wrong place.

I am working on a project to measure the conductivity of multiple different beakers of (salt) water at the same time.
For the sensors, I have this in mind: https://www.atlas-scientific.com/produc ... 1_kit.html
Now I was wondering, can I read out multiple EC-sensors at the same time in one Raspberry? And if so, how many (if there is a limit)?

If not, what would you suggest for simultaneous readings?

For information, I want to read the conductivity of, for example, 8 solutions, every 5 seconds. The data (in mS/cm) should be saved in a (.csv) file.
Not neccesarily the same file.

Hi.

Have you done any research on the device you want to use ?

Considering it costs $239 I would have expected you to have read every bit of information on the web site.

A quick look at the web site suggests it supports I2c so as long as each device can be set with a different device address you should be able to connect more than one.

I suggest you read the specifications sheet and look at the example software they provide to see what's possible.
