Application of 84131 AZ Dissolved Oxygen Pen:
The portable 84131 AZ DO meter can measure the dissolved oxygen level in water with unit of mg/l in liquid. And the 84131 AZ DO meter would be useful in a variety of applications where it is important to monitor dissolved oxygen levels in water.

1. Aquaculture:
Measuring dissolved oxygen value in water is critical in aquaculture operations to ensure that the fish or other aquatic organisms are getting enough oxygen to survive.
84131 AZ DO PEN can be used to measure the oxygen levels in fish tanks, ponds, or other aquatic environments.

2. Water treatment:
Dissolved oxygen levels are important in the water treatment process, particularly in the biological treatment of wastewater.
84131 AZ Dissolved Oxygen Pen with Floating Probe can be used to measure oxygen levels in aeration tanks and other treatment processes.

3. Environmental monitoring:
Dissolved oxygen value is an important indicator of water quality and can be used to assess the health of aquatic ecosystems.
84131 AZ Dissolved Oxygen Pen can be used to monitor dissolved oxygen levels in lakes, rivers, and other bodies of water.

4. Research:
Dissolved oxygen value can be an important parameter in scientific research, particularly in studies of aquatic organisms and ecosystems.
84131 AZ Dissolved Oxygen Pen can be used by researchers to measure oxygen levels in laboratory experiments or in the field.

The 84131 AZ Dissolved Oxygen Pen was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
