Built-In TEMP Electrical Isolation Digital PH Probe For Industrial Process Monitoring
The digital pH sensor adopts the classic electrochemical principle,
which is reliable in measurement and stable in performance. It is
widely used in environmental protection water treatment, surface
water, purified water, circulating water and other systems, as well
as electroplating, electronics, printing and dyeing, chemical,
food, pharmaceutical and other process fields. Excellent
performance in sewage treatment, drinking water treatment, surface
water monitoring, pollution source monitoring, industrial process
and other applications.
In order to obtain the best measurement results, regular
maintenance is required. Maintenance includes cleaning of
electrodes and checking for damage. Check whether the
electrode wiring is correct, check the communication setting
parameters (address, baud rate, parity bit, stop bit), etc.

FAQ
1. What is the measurement principle of this pH electrode?
A: The pH value potentiometric method uses the potential difference
of glass electrodes for pH measurement.
2. How to judge the pH of the solution?
A: If the internal hydrogen ion concentration of the pH glass bulb
is lower than the outside, the measured solution is recorded as
acidic and the pH value is lower than 7; if the two are the same,
the solution is neutral and the pH value is equal to 7; if the
internal hydrogen ion concentration is higher than externally, the
measured solution is alkaline and the pH value is higher than 7.
3. What is the wire length of the pH electrode?
A: The lead wire of this electrode is 1 m by default, other lengths
need to be customized, contact our customer service, the price will
vary with the change of length.
