Three-Point Calibration Methods PH ORP Transmitter For Water Online Monitoring
Electronic online monitoring of PH/ORP value, and remote
transmission to the monitoring room through RS485 or current
transmission for record keeping. It is one of the intelligent
online chemical analysis instruments. It is widely used in thermal
power, chemical fertilizer, metallurgy, environmental protection,
pharmaceutical, biochemical, food and tap water for continuous
monitoring of PH value or ORP value and temperature in solutions.

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.
