Specifications

The MW600 is a compact Portable Dissolved Oxygen meter
with Faster Micro Processor. This handy and ergonomically
designed portable meter is ideal for anyone working on a
low budget and still requires fast and reliable measure-
ments. This portable meter measures Dissolved Oxygen
with a Polarographic probe and is suitable for a wide range
of applications, such as Educational and Aquaculture, as
well as water and environmental analysis.
The MW600 calibrates easily in 2 points (at 100% saturated
air and in 0 Oxygen solution) and has Automatic
Temperature Compensation which guarantees the highest
accuracy.
Other features include smaller, ergonomic and lighter case
design, 100% larger and easier to read LCD Display, low
battery warning, easy to replace screw on cap membranes
and long battery life.
Rugged Carrying Case (Optional) provides handy on-site
meter calibration and measurements.
MW600 is supplied complete with a MA840 D.O. polaro-
graphic probe with 3 m cable, calibration screwdriver, 2
spare membranes, MA9071s (30 mL) electrolyte solution,
battery and instructions.
Ordering Information
MW600 is supplied complete with MA840 probe, 2 spare
membranes, 20 mL bottle of electrolyte solution, calibra-
tion screwdriver, 9V battery and instructions.
ALTITUDE & SALINITY COMPENSATION:
If the sample contains salts or if you are performing the measurements at alti-
tude different from sea level, the readout values must be corrected, taking into
account the lower degree of oxygen solubility.
Altitude Compensation:
all the readouts are referred to sea level, thus the dis-
played measurements are higher than the actual values. In fact, altitude affects
D.O. concentration by decreasing its value.
The table on the left reports the oxygen solubility at various temperatures and
altitudes, based on sea level barometric pressure of 760 mmHg.
This gives an idea of the error that can be introduced at different altitudes and
allows to calculate the quantity to be subtracted to correct the reading.
