Thermo Scientific™ Orion Star™ A329 pH/ISE/Conductivity/Dissolved Oxygen Portable Multiparameter Meter
Shop All Thermo Scientific ProductsGet high accuracy and premium performance everywhere you need it with the Thermo Scientific™ Orion Star™ A329 pH/ISE/Conductivity/Dissolved Oxygen Portable Multiparameter Meter. This meter is 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.
- 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
