Orion Star Benchtop Meter Series

4 Star pH/mV/DO/Temperature Meter

Easy to use 3-button function
Bright LCD display with ready indication
Convenient built-in Quick-Start Guide
Automatic barometric pressure compensation
Stores up to 10 methods with password protection

This competitively-priced, dual channel and dual display pH/DO meter is easy to set up and use while providing reliable measurement of pH and dissolved oxygen for water testing applications.
The rugged meter features enhanced stability indicators, salinity correction and automatic barometric pressure compensation and offers a full complement of GLP-related features?including available 21 CFR Part 11 software option.

Selectable 1 to 5 point pH calibration ensures accuracy even at extremes of concentration; dissolved oxygen calibration to the Winkler Titration improves accuracy by direct measurement of O2 concentration rather than inferring the concentration from temperature and pressure. SMART STABILITYTM and SMART AVERAGINGTM functions simplify the measurement process. You can record and store up to 10 setup parameters and calibrations.
