VIKING-PH200 Benchtop pH Meter
OVERVIEW
The VIKING-PH200 benchtop pH meter combines a bright 6.0″ backlit LCD with simple
operating logic for routine pH and mV measurements. It supports Auto-Read and
continuous read modes with Auto-Hold endpoint detection, ATC/MTC temperature
compensation and 1–3 point pH calibration with NIST buffer recognition.
With 50 data sets per parameter, clear status prompts (Reading / Stable / Locked), IP54 splash
protection and universal AC adapter, VIKING-PH200 is a practical, cost-effective platform for
education, COLO.Science water quality routines and general benchtop pH/mV tasks.
