PROBE & MEMBRANE MAINTENANCE:
The D.O. probe body is made of reinforced plastic for maximum
durability.
A thermistor temperature sensor provides temperature
measurements of the tested sample. It is always recommended
to keep the protective cap on the probe when not in use, to
protect the membrane against damage and dirt.
To replace the membrane or refill it with electrolyte, see page 1.
For example, if the measurement displayed at 10°C is 5 ppm,
but the sample has 20 g/L of chloride, to correct your measurement
multiply the displayed measurement by the ratio of (ppm reading
at 20 g/L) / (ppm reading at 0 g/L) = 5.0 ppm X (8.9 ppm/11.3 ppm)
= 3.93 ppm (or 3.9 ppm Chloride or Salinity corrected).
