Hanna Instruments Water Analysis Division has released the HI 3810 dissolved oxygen chemical test kit.
The kit can be use to monitor aquatic ecosystems, to which roper dissolved oxygen levels are essential. A dissolved oxygen level of 5mg/L or greater will support healthy growth of most fish species.
Other applications for the test kit include monitoring in wastewater treatment and heating plants. The kit uses an adaptation of the Winkler method to determine dissolved oxygen level.
