Thermo Orion Lab Star PH111 pH/mV bench meter

• Budget-friendly pH meter for simplified pH and ORP testing
• Display shows pH, mV and temperature simultaneously for accurate data recording
• Measure -2.000 to 18.000 pH, -2000.0 to +2000.0 mV and -5.0 to 105.0 °C or 23.0 to 221.0 °F to ensure comprehensive measurement capabilities
• Perform one to five point pH calibrations, one point ORP calibrations and one point temperature adjustment calibrations for proficient SOP compliance
• Large 5 inch backlit display makes viewing and recording measurements easy
• Small meter footprint saves valuable bench space in your lab
• Onscreen stabilizing and ready indicators help identify when readings are complete
• pH electrode condition icon helps ensure reliable electrode performance
• Date and time data stamped data and calibration logs support GLP compliance
• View active pH, ORP and temperature calibration logs with date and time stamp to ensure accurate, reproducible measurements
• Use 500-point data log with date and time stamp to record key measurements
• Output data and calibration logs to a printer or computer for long-term data storage

Models:

• LSTAR1110 (640-220-12) is the pH meter and stand option, which allows you to purchase your pH electrode separately
• LSTAR1115 (640-220-14) is the standard pH meter kit option, for common pH samples such as drinking water, tap water, buffers (non-TRIS) and general purpose student use
• LSTAR1116 (640-220-16) is the easy-to-clean bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides or other components that can interfere with silver-chloride; included refillable pH electrode is easy-to-clean and restore
• LSTAR1117 (640-220-18) is the low-maintenance bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides or other components that can interfere with silver-chloride; included gel-filled pH electrode is low-maintenance and easy to operate
• LSTAR1118 (640-220-20)is the difficult sample pH meter kit option, for pH samples that are thick, viscous or semi-solid including foods, beverages, wastewaters, emulsions, soils, slurries, suspended solids or sludges
