Digital Dissolved Oxygen Meter JPB-70A

Product Overview:
The Digital Dissolved Oxygen Meter JPB-70A is a practical portable instrument for measuring dissolved oxygen in water while also displaying water temperature. Its pen-style handheld design makes it convenient for routine water quality testing in different locations, including aquaculture facilities, fish farms, ponds, laboratories, educational environments, and general water-testing applications.
Dissolved oxygen, commonly abbreviated as DO, is an important water quality parameter because aquatic organisms depend on oxygen dissolved in water. Monitoring DO can help users understand changing water conditions and make informed decisions about aeration, water management, and aquatic environments.
The Digital Dissolved Oxygen Meter JPB-70A combines a compact digital meter with a separate probe connected through a flexible cable. The probe can be placed into the water being tested while the main display remains easy to hold and observe. Its digital LCD provides a convenient way to read the measured value and temperature during testing.Explore more lab related products on our store.
