DO Meter is a monitoring device that is used to measure the dissolved oxygen levels in water. Dissolved oxygen is an important parameter for the aquatic environment as it is crucial for the survival of aquatic organisms and indicates the overall health of the water body.
DO meters typically consist of a probe or sensor and a display unit. The probe is inserted into the water body and measures the concentration of dissolved oxygen, which is then displayed on the unit in various units such as ppm, mg/L, or % saturation.
DO meters are commonly used in wastewater treatment plants, fish farms, and aquaculture operations to monitor dissolved oxygen levels in tanks and ponds. They are also used in environmental monitoring programs to assess the health of aquatic ecosystems.
There are various types of DO meters available in the market, ranging from simple handheld devices to sophisticated laboratory-grade instruments. Some DO meters also come equipped with additional sensors for measuring other water quality parameters such as temperature, pH, and conductivity.
Regular calibration and maintenance are important for accurate readings from DO meters. The probes should be properly cleaned and stored when not in use, and the unit should be calibrated at regular intervals to ensure reliable and accurate measurements.
