Thermo Scientific Orion Star A212 Benchtop Conductivity Meter for Multi-Parameter Water Analysis
Product Description
The Thermo Scientific Orion Star A212 is a precision benchtop conductivity meter designed for laboratory measurement of conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature. Suitable for biotechnology and molecular diagnostics laboratories, this instrument supports a broad measurement range from 0.001 µS/cm to 3000 mS/cm with high resolution and automatic ranging, enabling accurate analysis across ultra-pure to high conductivity samples.
Key technical features include:
- Multi-parameter measurement modes: Conductivity, TDS, salinity (practical and natural seawater modes), resistivity, and temperature
- Wide measurement ranges and high accuracy: For example, conductivity accuracy at 0.5% of reading ±1 digit and temperature accuracy of ±0.1°C
- Compatible with 2-cell or 4-cell conductivity sensors featuring built-in temperature compensation supporting linear, nLFn, nLFu, and EP modes for precise readings in various water conditions
- Data management capabilities: 2000 data points stored with date/time stamps, password-protected methods, alarm outputs, and data transfer via printer or PC
- Robust calibration system with conductivity calibration editing and temperature probe offset adjustment to maintain measurement reliability critical in bioprocessing and molecular cloning workflows
- Flexible power options using universal AC adapter or AA batteries for uninterrupted laboratory operation
- Compact and ergonomic design: Dimensions 24 cm x 18 cm x 11 cm and weight 6 lbs, suitable for benchtop setups in synthetic biology and environmental monitoring labs
This conductivity meter is widely adopted in fields requiring precise water quality characterization such as biotechnology research, biomanufacturing, and clinical diagnostics. Its advanced feature set supports essential applications including molecular biology protocols and bioprocessing quality control. The inclusion of multi-language support and automatic data logging further enhances usability for research professionals focused on fluorescence analysis and live-cell imaging where precise buffer and reagent quality assessment is critical.
