Thermo Scientific ORION Star A211 Benchtop pH Meter
**This unit has been tested to specifications. Has minimal cosmetic blemishes from normal use. See photos for further details.
Record accurate and reliable pH, mV, ORP and temperature measurements with the Thermo Scientific Orion Star A211 Benchtop pH Meter and Orion 8302BNUMD Ross Ultra pH/ATC Triode. This meter is ideal for a wide range of applications and advanced pH analysis in the lab. Perform up to a 5 point pH calibration, 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 with free downloadable Orion Star software. Use the included electrode stand to easily place sensors in samples and simplify storage to minimize breakage.
