Thermo Scientific Orion Star A324 Multi-parameter Portable Meter

The Thermo Scientific Orion Star A324 Multi-parameter Portable Meter offers versatile measurement capabilities, including pH, mV, relative mV (RmV), ORP, and ion concentration (ISE) alongside temperature assessments. Compatible with a variety of probes—pH electrodes, ORP electrodes, ion selective electrodes (ISE), reference half-cell electrodes, and ATC temperature probes—this instrument ensures precise readings. The device boasts a pH range of -2.000 to 20.000 with an accuracy of ±0.002, and adjustable resolution settings of 0.1/0.01/0.001. Calibration can be conducted at 1 to 5 points for both pH and ISE measurements, offering a customizable user experience.

ISE measurement range extends from 0.0001 to 19900, with user-selectable units such as ppm, Molar, mg/L, %, ppb, or none, and an accuracy of ±0.2 mV or ±0.05% of reading. mV and relative mV readings feature a range of ±2000.0 mV with accuracy measures akin to the ISE specifications. ORP measurements also extend to ±2000.0 mV. The temperature range spans from -5.0°C to +105.0°C, promising an accuracy of ±0.1°C with 0.1°C resolution.

Additional features encompass high/low limit and calibration due alarms and comprehensive data logging modes, including both automatic and manual logging. The unit measures 240 x 100 x 65 mm and weighs 0.5 kg, ensuring portability. The package now includes the new Thermo Orion calcium electrode, enhancing capabilities for assessing calcium concentrations in aqueous solutions.
