Description
The Orion Star A Series by Thermo Scientific offers rugged, reliable, field‑ready and benchtop measurement tools from pH/conductivity to multi‑parameter analysis. Whether you’re in the field or the lab, these meters and accessories deliver precise readings with robustness and flexibility.
- Durable design: rugged housings, often waterproof (e.g. IP67 in portable models), textured controls usable with gloves or when wet.
- High accuracy and resolution: e.g. pH resolution down to 0.001 in higher‑end models; tight tolerances for conductivity, TDS, resistivity, salinity.
- Data logging & connectivity: capable of storing thousands of data points with sample/user IDs, date/time stamps; compatibility with PC software via USB/RS232.
- Accessories / options: field cases, protective armor, various probes (4‑cell, etc.), optional universal AC adapters.
