Portable Meter Kit

Accurately measure pH, dissolved oxygen and temperature with our pH/DO/RDO portable meter for high performance in challenging field tests.

Get high accuracy and premium performance everywhere you need it with the Thermo Scientific™ Orion Star™ A326 pH/Dissolved Oxygen Portable Multiparameter Meter. This meter is designed for a wide range of pH, mV, ORP, 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 two meter channels to measure pH and dissolved oxygen simultaneously or view each channel separately. Log up to 5000 data point sets with time/date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.

Take your measurements at the source with our premium line of portable meters. The Thermo Scientific Orion Star A326 pH/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 A326 pH/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 meter and dissolved oxygen meter in one easy-to-use system
  • Measure pH, mV, relative mV or ORP with temperature on channel one and measure dissolved oxygen in percent saturation or mg/L with temperature using RDO optical DO probes or polarographic DO probes on channel two
  • 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 a 5 point pH calibration using automatic buffer recognition of NIST or DIN buffer groups with choice to manually enter custom buffer values and calibration editing option that allows individual points to be fixed without a full recalibration
  • 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 5,000 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
