Thermo Scientific Orion Star A123 portable dissolved oxygen meter offers a simple and cost-effective solution for routine outdoor sample analysis. The entry-level Orion Star A123 dissolved oxygen meter features distinct measurement keys, optional reading modes, and a measurement stability indicator, all designed to provide reliable measurements at an affordable price.
Utilize a polarographic dissolved oxygen (DO) probe to measure the percentage saturation of dissolved oxygen or mg/L value, as well as temperature.
Calibrate using saturated air with moisture or custom values (Winkler titration)
Automatic compensation of DO readings through ATC temperature, manual salinity input, and manual barometric pressure adjustment.
A simplified, easy-to-read display shows the main measurements, along with temperature, stability indicators, and electrode status icons.
User-friendly operation with basic calibration prompts
Easily access calibration data for program verification
Even in the event of a power outage, non-volatile memory can retain 50 points of internal data logs and instrument settings.
Flexible power options, available with AA batteries or an optional universal power adapter
IP67-rated housing is waterproof, sturdy, and durable, suitable for on-site operations.
The measurement kit includes: a rugged field jacket for the instrument, with an electrode holder, adjustable wrist/waist strap, and an integrated instrument mount.
The meter comes with CE, Tripple合一 TUV, and FCC A Class certification.
