silica analyzer
in our plant we have three silica analyzers two of them are multistream and one is a single stream. receantly the single stream analyzer showes the following messages(alarms):
control temperature stabilising.
control temperature high.
the optical system temperature becomes 131.5 C
and the reation block temperature is 127.2 C but that is not the real temperature. the zero offset is -73.2 ppb and the control temperature equal to 44.7 C. the reading of the analyzer is zero and out of service alarm is appearing.
can any one help me to rectify the analyzer to gives the correct reading (about 5 ppb)
