Thermo Scientific Orion Star A329 Portable pH/ISE/Conductivity/RDO/DO Meter

Obtain measurement results at the source with our advanced portable meter series. The Thermo Scientific Orion Star A329 Portable pH/ISE/Conductivity/RDO/DO Meter offers an informative screen and user-friendly operation. This durable, portable, and waterproof meter meets all your basic application needs. As an easy-to-use and reliably designed field meter, the Orion Star A329 Portable pH/ISE/Conductivity/RDO/DO Meter provides advanced features and functions, including 5000-point date logging with sample ID and user ID options, calibration, high/low limit alarms, and measurement methods with password protection.

Combining pH/ISE, conductivity, and dissolved oxygen meters into one easy-to-use system offers greater convenience and benefits.

Measure pH, ion concentration, mV, relative mV, or ORP and temperature on Channel 1; conductivity, TDS, salinity, or resistivity and temperature on Channel 2; dissolved oxygen (as % saturation or mg/L) and temperature on Channel 3 using an RDO optical DO probe or polarographic dissolved oxygen (DO) probe.

View complete single measurement results easily in full-screen display, or quickly switch to split-screen display to view multiple measurements simultaneously.

Calibration editing options support single-point correction without full recalibration, allowing up to 5-point pH and ISE calibration.

Perform up to 5-point conductivity calibration.

Automatic conductivity range setting supports continuous readings across the full measurement range without recalibration.

Use linear, nonlinear, EP (USP), or turn off conductivity temperature compensation (reference temperatures: 5°C, 10°C, 15°C, 20°C, or 25°C).

Calibrate dissolved oxygen using water vapor-saturated air, air-saturated water, custom values (Winkler titration), and zero-point options.

Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input, and a built-in barometer (atmospheric pressure measurement).

An informative, easy-to-read backlit graphic display and clear on-screen indicators simplify operation.

Obtain critical readings with measurement stability indicators and optional reading modes—Auto Read holds stable readings, Continuous Read with hold option shows changing readings, and Timed Read logs data at specific intervals.

Data logging with date/time stamps for up to 5000 measurement sets, including optional sample ID and user ID.

Calibration log stores the 10 most recent calibration results.

Non-volatile memory ensures your data and settings are protected even during power loss.

Orion Star Com software transfers data to a computer via USB or RS232 connection.

Flexible power options using AA batteries or an optional universal power adapter.

IP67-rated housing is waterproof, rugged, and suitable for field operation.

Meter kit includes: a hard-surface field case and meter protective cover with electrode holder, adjustable wrist/waist strap, and built-in meter stand.
