This Thermo Scientific Orion VERSA STAR pH/mV/Temperature with LogR technology module easily connects into VERSA STAR meters. The pH/Temperature module allows up to 5 point pH calibration with automatic recognition for USA/NIST and DIN buffers. It also allows for fixing of calibration errors without a complete recalibration with calibration editing. The LogR technology provides the benefits of the most advanced electrode diagnostics and no temperature sensor needed to get temperature compensated pH readings. No need to turn off your meter to switch modules -meter automatically recognizes module changes. pH—Range: -2.000 to 20.000. Resolution: 0.1, 0.01, 0.001. Relative Accuracy: ±0.002.
