What is the mV reading? Does this measure conductivity?

We downloaded the material. Transmitter A transmitter (generally referred to as a 'transmitter' in the field) is an instrument that transmits electrical signals (such as analog or digital signals) input from various sensors that are detection units to other equipment over a short or long distance. For example, a pH transmitter receives a mV signal from a pH electrode. This electrical signal is calculated inside the transmitter and converted into DC4~20mA or DC1~5V analog signal or digital signal and output. At this time, the pH transmitter gives a bias of 4mA so that it corresponds to 4mA at 0pH and 20mA at 14pH so that it can be distinguished from '0' in general. We don't know the details either. But if you look at the data, you can understand it to some extent. You will also understand. Thank you.

Does the pH-11 meter measure hydrogen ions or conductivity?

Hi, This product is a machine for measuring acidity (pH). There is a separate product that measures the conductivity. Thank you.

Does this work with testing blood pH?

The pH value of mammals is normally controlled around 7.35-45 in the body. Once outside the blood vessels, blood pH easily falls outside this range due to atmospheric and temperature effects. This pH meter will respond to blood, but the value should not be considered to be with the sealed and temperature-controlled blood sample values that are measured in the lab.

A useful meter

I am using the pH-11 to measure the pH values of natural water samples that are not buffered. So the pH values are expected to be variable. What matters is the general trend observed. And this little meter seems to be doing a good job. If you follow the instructions and watch a few of the videos posted by Horiba on YouTube, you should not have any trouble using these meters. Make sure you cover the entire bottom of the sample chamber (both the reference and the pH electrodes) with your sample. Also rinse the electrodes with your sample once before measuring its pH. I have asked a few technical questions by filling out the form on Horiba’s webpage and received helpful answers within a day.

Works Very Well

Really like that the sample size can be very small, such as 0.5ml. And it comforting to know that this $130 pH meter agrees with the $20 pH meter I also own. :)

Not suitable for low ph

Seems like a nice meter but the description on amazon does not disclose that this meter should not be used for ph below 3 (or above 9) so I had to return it. It also arrived with the electrode dried out.

It was slightly dirty and the plastic areas over the buttons is discolored

The product was advertised as new but is not. It was slightly dirty and the plastic areas over the buttons is discolored. It gives an error message during calibration.

Why calibration so hard?

I tried to calibrate mine before using, and it calibrated 7.0 fine, then it automatically started calibrating the 4.01 point while the 7.0 fluid was still in there which screwed it up. I could not get it to recal the 7.0 sample. Then I switched to 4.01 fluid thinking I'll calibrate that and then redo 7.0 but then it started calibrating for 10.0 point, which this pH11 model is not supposed to be able to do at all, it's only a 2 point calibration model. It tried to calibrate 10.0 with 4.01 fluid and that apparently broke it. Instruction manual does not adequately explain how to calibrate. Now I just get Er4 message, means broken sensor. I never used it once. It never touched anything except 7.0 and 4.01 test fluids. New sensor $110.

Easiest most practical Pocket Small Sample ph Meter

I loved it. Had to measure the ph values of bread & butter pickle relish.
