Ohaus ST300-G pH Portable Meter

Ohaus pH Portable Meter is a meter to allow you to measure pH and Oxidation-Reduction Potential (ORP) conveniently and accurately. The ST300 portable water analysis meters were created with versatility in mind. They can be operated in the lab with the support of built-in stand, or in the field with the wrist band.

Automatic and manual temperature compensation ensures accurate readings while a 30 measurement library stores data for future reference.

Each time the meter is calibrated, icons appear on the display to confirm the accuracy of the calibration process so you can ensure accurate measurement.

The auto buffer recognition stores calibration data and helps to avoid errors during the calibration process.

Easy to use with a clear, well-organized LCD screen.

IP54 protection which shields the meter from damage by water and dust particles.
