Model 92-50 Dissolved Oxygen Meter
Portable, battery operated, and microprocessor controlled the Jenco 92-50
is a completely self contained instrument for measuring dissolved oxygen in the
lab or on location. The instrument provides 3 distinct measurements; the
CURRENT TEMPERATURE, the DISSOLVED OXYGEN % a measurement of oxygen in percent
saturation and the DISSOLVED OXYGEN PPM, a measurement of oxygen in ppm. A mode
key toggles the display between ppm and % saturation. Temperature is always
displayed. The DO kits detailed below contain everything you need to start
taking DO measurements.

| Dissolved Oxygen is a measure of the
free oxygen dissolved in water. It is an indicator of water quality. The amount
of oxygen that can be held by the water depends on the water temperature,
salinity, and pressure. Gas solubility increases with decreasing temperature
(colder water holds more oxygen). Gas solubility increases with decreasing
salinity (freshwater holds more oxygen than does saltwater). Both the partial
pressure and the degree of saturation of oxygen will change with altitude .
Finally, gas solubility decreases as pressure decreases. Thus, the amount of
oxygen absorbed in water decreases as altitude increases because of the
decrease in relative pressure. |
