The MO-200 is a a hand-held meter that displays and stores oxygen measurements.
It is designed to measure 0 to 100 % oxygen and it is connected to an O2 sensor cable.
|The Sensor measures:||O₂|
Apogee MO-200 handheld Oxigen meter.
This meter is useful for monitoring soil respiration, aeration, and gaseous O2 levels in laboratory studies.
It has a galvanic cell sensor with a lead anode, a gold cathode, an acid electrolyte and a Teflon membrane.
The current flow between the electrodes is proportional to the oxygen concentration being measured.
An internal bridge resistor is used to provide a millivolt output.
Being a galvanic cell type sensor, a small amount of oxygen is consumed in the reaction in order to produce the current flow and subsequent mV output.
The oxygen consumption was measured to be 2.2 micromols (μmol) O2 per day when the O2 concentration was 20.95% (3240 mmol) at 23 degrees Celsius.
Available optional head accessories: diffuser head and feed-through head (see Accessories).
