Advanced pH/ISE Benchtop Meter

Star A214 pH/ISE Meter
Star A214 pH/ISE meter

The Thermo Scientific™ Orion™ Star A214 pH/ISE Benchtop Meter is the ideal choice for any lab. Get the information you need quickly and easily from the large, backlit graphic LCD display.

The informative display shows pH, mV, RmV, ISE and temperature with electrode status, time, date, sample ID, user ID and calibration points.

Features and Benefits

  • Easy meter operation assured with on-screen text prompts, menu-specific function keys and a multi-language interface
  • Don't miss a reading - Ready indicator alerts when readings are stable, AUTO-READ™ locks in the stable reading on your screen, and timed reading gathers data in specific time intervals
  • Up to 5 point pH calibration with automatic recognition for USA (NIST) and DIN buffers or manual option for custom buffer values
  • Up to 5 point ISE calibration with optional non-linear auto-blank low-concentration stability
  • Non-volatile memory holds up to 2000 data points with time and date stamp
  • Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary Orion Star Com computer software
  • Stir samples with ease using the meter-controlled Orion Star stirrer probe
  • Included electrode arm and holder make it easier to maintain probes
  • Power the meter using the universal power adapter or four AA batteries
  • IP54-rated housing handles splashes and is wall-mountable to save space
