Calibration Value Settable PH Meter For Wastewater Online Monitoring
PH value is one of the important indicators of water quality monitoring, and it is a key link in the analysis and treatment of water environment. The pH value control of surface water is the most important.
The APX1-L1 pH controller is an intelligent online water quality analysis instrument, which is used to monitor the pH/ORP value online, and output it to the monitoring room for record keeping through RS485 or current transmission. Widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water industries.

FAQ
Q1. Does the instrument have a self-diagnostic function and how
does it prompt?
A: The pH meter has self-diagnosis function.When the instrument is
in calibration and maintenance,it can diagnose the PH/ORP sensor,if
there is improper operation or poor PH/ORP sensor characteristics,
the screen makes an image display and advises the user to
re-maintain or replace the sensor.
Q2. What are the special advantages of the pH instruments?
A: The instrument can not only compensate the temperature of the
test sample by connecting the temperature sensor, but also
self-check the working temperature of the instrument in real time.
When the working temperature of the instrument changes, the
instrument compensates the hardware change caused by the
temperature drift. Make the test results more accurate, this is a
patented technology.
