Thermo Scientific Orion Star A111 pH Benchtop Meters combine simplicity with accuracy
A large LCD displays pH or mV readings along with temperature
Icons provide quick updates on battery life, electrode status and calibration information
Simple button layout and onscreen messages help with calibration and setup menu choices
Large, informative screen clearly shows the main information, including pH or mV reading, temperature, meter mode, calibration information and power source Don't miss a reading — Auto-Read measurement mode locks in the stable reading on your screen and ready indicator alerts when readings are stable Up to three point pH calibration Automatic recognition of USA/NIST and DIN buffers Easily recall calibration slope data for procedure checks Non-volatile memory holds up to 50 data points Included electrode arm and newly-designed probe holder make it easier to maintain and place probes into samples Plug the meter into almost any power outlet with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power The IP54-rated housing can handle splashes and can be wall-mounted if table space is a problem Specifications Accuracy (mV): ±0.2 mV or ±0.05% of reading whichever is greater Accuracy (pH): ±0.01pH Battery Life: 2000 hours Inputs: BNC (pH), 8-pin Mini-DIN (temperature) Probe Type: ±pH electrode, ATC probe, ORP electrode - purchase separately Range (mV): 1600.0mV Range (pH): -2.00 to 16.00pH Relative Humidity Range: 5 to 85 %, non-condensing Resolution (mV): 0.1mV Range (Relative mV): ±1999.9 RmV Resolution (pH): 0.1, 0.01pH Temperature (Metric) Operating: 5 to 45°C Temperature Range: -5° to +105°C Calibration Points (pH): 1 to 3 Certifications CE, TÜV, FCC Class A limits , IP-54 Warranty and Services Three-year meter replacement warranty
