Description

Get high accuracy and premium performance everywhere you need it with the Thermo Scientific™ Orion™ Star A329 pH, ISE, Conductivity, DO and RDO Portable Meter, designed for a wide range of pH, ion concentration, conductivity, dissolved oxygen and temperature testing and field applications. Evaluate samples in the most demanding locations using this waterproof meter with IP67-rated housing. Use the three channels to measure pH, conductivity and DO simultaneously or view each channel separately. Log up to 5000 data point sets with time / date stamp and transfer to a printer or computer.

Large, Backlit Informative Graphic LCD:

• User can view each parameter individually, two parameters simultaneously or all three parameters on one screen; all options are shown with temperature.
• Helpful icons are shown for electrode status, time, date, sample ID, user ID and calibration data.
• Informative screen prompts guide meter setup and calibration procedures.
• Menu-specific function keys automatically update to ensure easy meter navigation.
• Multilanguage interface supports English, Spanish, French, Italian, German and Chinese.
• Thermo Scientific™ AUTO-READ™ locks in a stable reading on the screen; ready indicator alerts when continuous readings are stable and timed reading gathers data in specific time intervals.

pH, mV and ISE:

• Up to five point pH calibration is offered with automatic recognition of USA/NIST™ and DIN buffers.
• Up to five point ISE calibration with advanced features such as linear point-to-point, non-linear selectable auto-blank, and low-concentration range stability ensure accuracy whether ISE is done infrequently or with multiple samples every day.
• Calibration editing allows pH and ISE calibration errors to be corrected without a complete recalibration.

Conductivity:

• Automatic conductivity measurement ranging based on sample conductance and calibrated cell constant for the ideal display resolution
• Selectable reading reference temperatures of 5°, 10°, 15°, 20° or 25°C with linear, nonlinear, nLFu or EP curve options for advanced accuracy in conductivity readings
• Choice of practical salinity or natural sea water curves for salinity readings

Dissolved Oxygen:

• Automatically recognizes Orion polarographic and RDO optical/luminescence-based probes—no need to worry about compatibility
• Provides easy, accurate DO results with automatic temperature, automatic/manual barometric pressure, and automatic salinity compensation
• Calibrates by water-saturated air, air-saturated water, manual using a Winkler Titration or zero point calibration

Memory and Software:

• Nonvolatile memory holds up to 5,000 data points with time and date stamp.
• USB and RS232 ports and complimentary Orion Star Com data transfer software make data transfer to a computer fast and simple.

Meter Includes:

• Four AA batteries for more than 800 hours of operation, literature CD, printed quick start guide and USB computer cable
• Three-year meter replacement warranty
• Universal power adapter sold separately to use AC power (catalog number 1010003)
