The Thermo Elect.LED (Orion) Star A211 pH Benchtop Meter Kit is designed for precise and reliable pH measurements in water, process, research, and QA/QC samples. The large backlit graphic LCD provides clear readings for pH, mV, ORP, and temperature, along with electrode status, time, date, sample ID, user ID, and calibration points. Advanced features such as stability monitoring, averaging, and AUTO-READ ensure accuracy and efficiency in the laboratory.
