Thermo Scientific Orion Star A122 Portable Conductivity and TDS Meter with Temperature Compensation
Product Description
The Thermo Scientific Orion Star A122 is a portable conductivity meter designed for precise measurement of conductivity, total dissolved solids (TDS), and temperature with temperature compensation at 20°C or 25°C reference points. It features:
- Measurement ranges: Conductivity from 0.01 µS/cm to 200.0 mS/cm; TDS from 1 to 19,999 mg/L
- Resolution and accuracy: Conductivity resolution down to 0.01 µS/cm with 0.5% reading ±1 digit accuracy; TDS accuracy also at 0.5% reading ±1 digit
- Temperature measurement: Range from -5°C to 105°C with ±0.1°C accuracy, utilizing linear temperature compensation
- Display: Easy-to-read backlit LCD with on-screen guidance for user-friendly operation
- Data storage: Stores up to 50 data points for efficient field data management
- Power options: Operates on 4 AA batteries or via 120V electrical supply, supporting portability
- Durability: IP67 rated for waterproof protection, making it suitable for demanding lab and field environments
This handheld conductivity meter is widely used in biotechnology, molecular diagnostics, and bioprocessing applications that require accurate monitoring of ionic concentration and TDS during sample preparation and synthetic biology workflows. Its portability and rugged design make it critical in biopharmaceutical production pipelines and environmental monitoring often integrated within research laboratories focusing on cell imaging and clinical diagnostics.
The Orion Star A122's precise temperature compensation and broad measurement range render it essential for molecular cloning workflows and various life science applications where reliable conductivity and TDS measurements influence experimental integrity.
