DESCRIPTION

OBS-3A combines OBS probes, pressure sensors, temperature sensors, and conductivity sensors together, powered by batteries, and can record data internally. The monitoring software needs to run on Windows 982000 and XP operating systems.

Users can program the sampling sequence through a PC, and during the measurement period, the data is displayed and stored in real-time. During automatic operation, the instrument's measured data is recorded on internal FLASH storage and can be processed through WXCEL or LOTUS.
