Help with Water Conductivity EC Sensor

Using Arduino Sensors
#1

I am currently using EC sensor from DFRobot for my hydroponics project. Here is the link to the product:

https://www.dfrobot.com/product-1123.html

As the sensor probe is too fragile. I ordered a industrial EC sensor probe. Here is the link for the same:

This probe is similar to the DFRobot one except it has a stainless steel cover to protect it and a thread joint to add it inline with the plumbing. I tried using this with the DFRobot analog chip but it does not work. I can measure the temperature with a 10k resistor as the temperature compensation cell is NTC10K.

Please help me how to use this industrial sensor with arduino. I have attached sensor photo for your reference.

Thanks and Regards,
Sanket Patel.

What do you mean by "it does not work"?

#3

It does not give any reading with the same code. The result is 0.

#4

Have you tried measuring the resistance between the resistance leads with a multimeter to sanity check it?
