We are looking for ph sensor kit for real time monitoring of pond water.Is this FIT0348 is suitalbe for industrail use??We are planning to use the SEN0169 Model.In the description ...

What is the sensitivity of the pH meter? Can it detect 0.1 change in pH value?

Hello, is this a replacement probe for the pH meter pro or pH meter pro V2?

do you sell the transparent plastic covers by themselves?

Hello, I'm testing pH sensor(FIT0348). but I don't know if the sensor is OK.
The sensor output range seems strange.
For example, at pH 4.0, it should be 177mV, but only 5mV comes out.
and at pH 10.0, -3mV comes out.
Is this correct?

Hi.. i have just installed Sen0169 for a week. And now it's not functioned well (pH value detected stable at 16). Any ideas for me to troubleshoot this ?

Hello!
I need the most accurate sensor to connect to the Arduino.
You have a version of the sensor "Industrial pH Electrode - Armor Casing" on the site with an accuracy of <0.02рН, but it says there, this is a sensor intended for modification Analog pH Meter (SEN0161) . This means that in order to use an accurate sensor, do I need to buy a regular sensor as well?
In a similar Pro version, the accuracy is already for some reason ±0.1рН.
I find it difficult which option suits me. Either you have a typo that the pro version has an accuracy of 0.1, or I need to buy two sensors at once, Analog pH Meter (SEN0161) and Industrial pH Electrode - Armor Casing.
And can i connect Industrial pH Electrode - Armor Casing to Arduino?
Can you help me please?

have you ever had issues with customs when shipping this probe to Mexico? (I ask because of the liquid it has)

Hello everybody,
is the probe/electrode waterproof? I mean, I need to install it on field in wetted soil that is supposed to be exposed to the heavy rain: is it with some water protection class like IP67?
Thank you in advance for the support!

Hello, i connect this sensor to arduino yun and output is 496, is correct? output = analogRead(A0)
phvalue = 3.5*(analogRead(A0)* 5.00 / 1024) is correct?

I ordered the industrial PH sensor, i broke the BNC Connector though. Is it possible to buy one BNC Connector by itself?

Ordered PH sensor, got without storage fluid in the protective cap - all fluid was leaked. Seller only suggested to soak PH sensor in the 3.3mol/L potassium chloride solution which i do not have. I suggest not to buy PH sensor from dfrobot because you can get unconditional item.

We sell them all as you can see. If you need a industrial version, we have kits for sale.https://www.dfrobot.com/product-111...

You can purchase PH V2.0 here.https://www.dfrobot.com/product-102...

Hi, Is this probe compatible with board ph Meter V2.0 found in SEN0161-V2 kit? I'm asking because our system can provide only 3.3V.

You can immerse in water for a long time, but you still need to calibrate it every half an year.

Hello, what is the protection IP of the sensor?

how much pressure the probe can handle when submerged in a tank

Hi, I would like to know if you also have temperature, Dissolved Oxygen, EC annd ORP sensors pepared to be 24x7 hours submerged, for making an automatic water monitor as this one: https://www.dfrobot.com/blo...
I have seen that the DO sensor in that project is from Atlas Scientific (witch is prepared to measure continiously 24x7), so Im wondering if you have or are going to develop another sensor of this type.
Thanks!

For replacing the electrode, you need to replace the whole electrode, and this product is the electrode. For the maintenance, you'd better not use it in strong acid or strong alkali solution and you'd better calibrate the sensor sometimes.

Would this probe be suitable for long-term submersion in ~1.8pH solution, or would that damage the probe? The probe would be pulled from the electrolyte for cleaning and calibration twice a week or so.
