Record accurate and reliable pH, mV, ORP, dissolved oxygen and temperature measurements with the Thermo Scientific Orion Star A216 pH, DO and RDO Benchtop Meter.

Ideal for a wide range of applications and advanced pH and dissolved oxygen analysis in the lab. Use the two channels to measure pH and dissolved oxygen simultaneously or view each channel separately. Use an RDO optical or polarographic DO probe for ultimate flexibility in sensors. Log up to 2000 data point sets with time / date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.

Thermo Scientific Orion Star A216 pH/RDO/DO benchtop meters are easy to use, dependable laboratory meters with advanced features and functions. Selectable read modes and stability indicator give you flexibility and control over your testing. All critical data is shown with your measurements including temperature, date and time, read type, measurement stability, active calibration information and electrode condition icon. Onscreen calibration and setup instructions can be displayed in several local languages with new languages added through software updates. 

Navigation is fast and simple due to the comprehensive keypad with menu-specific function keys, dual purpose scroll/shortcut keys, plus power, measure, log view and stirrer keys that ensure easy operation. All setup menus are in one location with direct access using a single shortcut key so you can quickly access, evaluate and change measurement and instrument settings.

  • 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 five 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
  • Eliminate the need for magnetic stir bars using the meter-controlled stirrer probe (catalog number 096019) to uniformly mix solutions
  • Data log collects and date/time stamps up to 2000 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 universal power adapter or optional AA batteries
  • IP54-rated housing resists dust and splashes and can be wall-mounted if table space is limited
  • Meters include CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty
