The BANTE8 series includes models 820 and 821, The meters are used to measure amount of gaseous oxygen dissolved in a liquids.

Features:
* 100% and zero adjustment calibrations in DO mode
* Manual or automatic temperature compensation for best accuracy under fluctuating temperatures
* Automatically compensates salinity and barometric pressure after manual input for increased accuracy
* Automatic message indicator to help you operate meter
* Expanded memory stores and recalls up to 48 data sets
* Built-in real-time clock stamps for stored data
* USB Communication interface
