instability
A, there are bubbles in the
pipeline
A, rectification of the pipeline or
alternative measurement points
Large reading
B, unstable water quality
B. Reasons for using a stable water
source to remove the meter
Dissolved
oxygen
Low test
Inappropriate flow rate
Install the conductivity cell at a
suitable flow rate
pH
pH meter cannot
be calibrated
Viscous substance
attached to the fluorescent
cap
Wipe with a soft, damp cloth
Not allowed
after calibration
Standard solution is not
properly formulated or the
electrode is damaged
Slow data
response
Is the standard liquid
contaminated?
According to the type of pollutants, it
is cleaned according to the
corresponding method. Slow winter is
normal.
Turbidity
The data is very
high
A, the front end of the
Sensor lens has
contaminants
B, scraping the lens to
block the front end of the
Sensor
