Question PH/EC Sensors
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
Hello
im interested in
EC-Sensors
https://www.dfrobot.com/product-1123.html
PH Sensors (Soil & Water? )
https://www.dfrobot.com/product-1110.html
or
https://www.dfrobot.com/product-1668.html
I test only normal Water with some Nutrient.. ( No Saltwater)
PH Range from 0,5 PH - 9 PH
EC-Range
0,3 - 4
I would like have senors they i can put longtime in the water .For a Project.
Questions
can i Use the PH-Probe
https://www.dfrobot.com/product-1110.html
for water & Soil ? and for water longtime... like 10 days/24 Hours ?
can i use the
https://www.dfrobot.com/product-1123.html
for long time tests like 10 days.. ?
if not. what i can do?...
is enough to clear the Probe after messure only with
distilled water ?
best regards
Jürgen

You can only use pH sensor PRO(SEN0169,https://www.dfrobot.com/product-1110.html) in the water. This is an industrial probe, so it can be used for long time, such as 24*7. But you need to clean and calibrate it regularly. if you want to use it to measure the soil, you need a water-strainer. That is, let the water flow through the soil, then filter it through the water filter to collect the water. Measure the water with the probe.
For the soil, you can directly use the spear tip pH sensor(SEN0249,https://www.dfrobot.com/product-1668.html). This probe can be inserted directly into the soil. Of course, when inserting, you need to avoid sharp objects such as sand. But this probe is a laboratory level probe, it can not be used for a long time. When measurement finished, you need to clean and stock it.
This Electrical Conductivity Sensor(DFR0300,https://www.dfrobot.com/product-1123.html) is also a laboratory level probe, so you can not use it for a long time. If could, you can replace it with an industrial probe whose k value is 1.0.
After every measurement, you can use the deionized water to clean the probe.
