Descrição
Discontinued. Replaced by DOH-10.
The DOH-SD1 is innovative and easy to operate. What
sets the DOH-SD1 apart from other dissolved oxygen meters is
that it incorporates a real-time SD card data logger. The DOH-SD1
measures dissolved oxygen and has adjustments for altitude and
salt. Download data from the SD card into an Excel spreadsheet.
This allows the user to do further data or graphical analysis without
special software. The DOH-SD1 has a wide variety of applications
from water conditioning, aquariums, and fish hatcheries to food
processing, educational and other laboratories.
