HACH, sensION156 Portable pH/ Dissolved Oxygen Meter, with Platinum pH Electrode & DO Probe ( 1-meter pH cable; 3-meter DO cable)
cat. 5465012

Versatile multi-parameter ISE field measurement, with high-confidence results.
Bring one instrument into the field with multi-parameter confidence. This new sensION156 meter has the capability to easily measure pH, ORP, dissolved oxygen, conductivity, TDS, salinity, and temperature. The sensION156 meter features an intuitive user interface, making it easy to navigate between parameters. You also get quick calibrations with automatic temperature corrections, for consistently accurate, worry-free results. Storing 199 points of data and downloading are made easy with Hach' s unique docking station, which also converts your battery-powered sensION156 to line power for lab use. Optional accessories, like BOD adapter, carrying case, and LIS chamber will further accommodate this truly flexible meter to your needs. The sensION156 package includes the apparatus necessary for complete multi-parameter testing in the field.
Hach sensION156 Meter provides multi-parameter confidence in one single instrument
