Discover the award-winning Orion Lab Star PH111 pH/mV bench meter. Measure pH or ORP simultaneously with mV and temperature. 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 stabilising 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.
