OS-DO03 portable dissolved oxygen measuring instrument from Oushi Technology adopts the first generation fluorescence lifetime technology, which does not consume oxygen, has no flow rate limitation, does not require electrolyte, is free from maintenance and calibration, is not affected by hydrogen sulfide interference, and has excellent stability. The sensor end is equipped with a built-in temperature sensor, which automatically compensates for the temperature of dissolved oxygen measurement. The measuring instrument comes with a portable handheld operator for outdoor sensor power supply, real-time display and viewing of data, on-site calibration and other functions. It also has a built-in pressure sensor that can automatically compensate for dissolved oxygen.
