The Milwaukee MI151-US is a high performance economy microprocessor-based pH, ORP, and temperature laboratory bench meter is an excellent tool for schools, laboratories, and production plants.

The MI151-US includes a series of diagnostic features which add an entirely new dimension to the measurement of pH, allowing the user to dramatically improve the reliability of the measurement (see features). The MI151-US can also measure ORP electrodes, thanks to its ability to measure mV with a resolution up to 0.1mV. For accurate measurements, use the electrode holer supplied with the meter.
