VIKING-PH500 Laboratory pH/mV Meter
OVERVIEW
The VIKING-PH500 laboratory pH/mV meter combines a 7.0″ color touchscreen with a
smart operating system for user, calibration, method and data management. It delivers
±0.002 pH accuracy, 0.001 pH resolution and 1–6-point calibration with standard
recognition and custom buffer groups for demanding electrochemistry workflows.
With ATC/MTC temperature compensation, multi-reading modes (Auto Read, Timed, Continuous),
EH ORP mode, GLP-compliant memory for 1000 data groups and USB/RS-232 connectivity,
VIKING-PH500 is a versatile COLO.Science platform for water and wastewater laboratories,
food & beverage QA/QC, pharmaceutical and biotechnology labs, and academic teaching labs.
