Question 1

What is the mV reading?  Does this measure conductivity?

Accepted Answer

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.

Question 2

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

Accepted Answer

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

Question 3

Does this work with testing blood pH?

Accepted Answer

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.
