Benchtop Dissolved oxygen meter LBDO-A11

Benchtop Dissolved oxygen meter LBDO-A11


Benchtop Dissolved oxygen meter LBDO-A11 is equipped with polarographic sensor to measure the dissolved oxygen content. The manual salinity & barometric pressure compensation helps in accurate measurement of dissolved oxygen. The system menu of dissolved oxygen meter can set 9 parameters such as stability conditions, calibration points etc. This meter stores and recalls up to 500 sets of data & data is transferrable to PC via USB interface.
