If the sample contains significant salinity or
if the measurement is taken at a higher
altitude than sea level, the readout values
must be corrected (by taking into account
the lower degree of oxygen solubility in such
conditions - see below).
With HI 9143, set the altitude and/or the
salinity before calibration and taking mg/L
measurements. The meter will automatically
compensate for these factors.
With HI 9145, the readout is at sea level and
for liquids without any salt content.

SATURATION READINGS
The % O
2
reading provides the rate of
oxygen saturation with reference to 100.0%
at sea level.
TEMPERATURE READINGS
The lower part of the display
will show the measured
temperature in Celsius
degrees.
Allow the probe to reach thermal equilibrium
with the sample before taking any
measurement. The greater the difference
between the ambient temperature and the
temperature of the sample, the longer it will
take the probe to acclimatized itself to the
sample.
