Orion™ Star A329 pH, ISE, Conductivity, Dissolved Oxygen, RDO and Temperature Portable Waterproof Multiparameter Meter

Take your measurements at the source with our premium line of portable meters. The Thermo Scientific Orion Star A329 pH/ISE/Conductivity/RDO/DO Portable Meter offers an information-rich screen and user-friendly operation. This rugged, waterproof portable meter is ready to tackle the elements with you. Orion Star A329 pH/ISE/Conductivity/RDO/DO Portable Meters are designed to be easy-to-use, dependable field meters that offer advanced features and functions including a 5000 point date log with sample ID and user ID options, calibration and high/low limit alarms and password-protected measurement methods.

• Combined convenience with the benefits of a pH/ISE meter, conductivity meter and dissolved oxygen meter in one easy-to-use system.
• Measure pH, ion concentration, mV, relative mV or ORP with temperature on channel one; measure conductivity, TDS, salinity or resistivity with temperature on channel two; and measure dissolved oxygen in percent saturation or mg/L with temperature using RDO optical DO probes or polarographic DO probes on channel three.
• Easily view individual measurements on a full screen display and quickly toggle to a split screen display to view multiple measurements simultaneously.
• Perform up to five point pH and ISE calibrations with calibration editing option that allows individual points to be fixed without a full recalibration.
• Perform up to a five point conductivity calibration.
• Auto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrate.
• Use linear, non-linear, EP (USP) or off conductivity temperature compensation with 5°C, 10°C, 15°C, 20°C or 25°C reference temperatures.
• Calibrate dissolved oxygen using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options.
• Automatically compensate dissolved oxygen readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure readings.
• Informative, easy-to-read backlit graphic display with clear onscreen instructions simplifies operation.
• Capture your critical readings with measurement stability indicator and selectable read modes — Auto-Read holds a stable reading, Continuous shows changing readings with hold option and Timed logs data at specific intervals.
• Data log collects and date/time stamps up to 5000 measurement sets with optional sample ID and user ID.
• Calibration log stores 10 most recent calibrations.
• Non-volatile meter memory ensures your data and settings are protected, even with loss of power.
• Orion Star Com software facilitates data transfer to a computer via USB or RS232 connections.
• Flexible power options with AA batteries or optional universal power adapter.
• IP67-rated housing is waterproof for rugged field operation.
• Meter kits include hard-sided field case and protective meter armor with electrode holders, adjustable wrist/belt strap and built-in meter stand.
• Meters offer CE, TUV 3-in-1 and FCC Class A certifications.
• 3-year replacement warranty.
