Orion Star A325 pH/Conductivity Portable Multiparameter Meter

Get high accuracy and premium performance everywhere you need it with the Thermo Scientific Orion Star A325 pH and Conductivity Portable Meter, designed for a wide range of pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature testing and field applications. Evaluate samples in the most demanding locations using this waterproof meter with IP67-rated housing. Use the two channels to measure pH and conductivity simultaneously or view each channel separately. Log up to 5000 data point sets with time / date stamp and transfer logs to a printer or computer.

Take your measurements at the source with our premium line of portable meters. The Thermo Scientific Orion Star A325 pH/conductivity 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 A325 pH/conductivity 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 conductivity meter in one easy-to-use system
  • Measure pH, mV, relative mV or ORP with temperature on channel one and measure conductivity, TDS, salinity or resistivity with temperature 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 five point pH calibration using automatic buffer recognition of NIST or DIN buffer groups with choice to manually enter custom buffer values
  • Perform up to a five point conductivity calibration
  • Calibration editing option allows individual points to be fixed without a full recalibration
  • 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, 10, 15, 20 or 25°C reference temperatures
  • 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 ten 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
