This Dissolved Oxygen meter is a pen-style tool that measures dissolved oxygen and temperature in water.
High sensitivity and accurate readings are enabled by a thin membrane kit and calibration in air. With a rechargeable environment-friendly battery, the device has a 5m cable for easy manipulation. It supports manual salinity and barometric pressure compensation and °C/°F automatic temperature compensation built-in. A big LCD with adjustable brightness ensures visibility in dark places.
The portable DO meter can measure the dissolved oxygen level in water with unit of mg/l in liquid. This meter is useful in a variety of applications where it is important to monitor dissolved oxygen levels in water, including:
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.
Environmental Monitoring
Dissolved oxygen levels are an important indicator of water quality and can be used to assess the health of aquatic ecosystems. The DO Pen can be used to monitor dissolved oxygen levels in lakes, rivers, and other bodies of water.
