Lab Star PH111 pH Benchtop Meters
Measure pH or ORP simultaneously with mV and temperature using the Orion Lab Star PH111 pH/mV bench meter. Featuring a large, backlit display for easy viewability and small footprint to save bench space, this pH meter is ideal for simplified, budget-friendly lab testing. Use the onscreen stabilizing and ready indicators to help identify when pH meter and ORP meter readings are complete. View active pH, ORP and temperature calibration logs with date and time stamp, record key measurements using the 500-point data log with date and time stamp, and output all logs to a printer or computer.
- H243-73 is the pH meter and stand option, which allows you to purchase your pH electrode separately
- H243-74 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
- H243-75 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
- H243-76 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
- H243-77 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
- 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 18.000pH, -2000.0 to +2000.0mV 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
