VIKING-PH300 Benchtop pH Meter
The VIKING-PH300 benchtop pH meter pairs a bright 7.0″ LCD with Auto/Timed/Continuous read modes, ATC/MTC temperature compensation, Auto-Hold endpoint lock, and 1–5 point calibration with buffer group recognition (NIST/DIN/GB/USA/GOST). It stores up to 500 results per parameter (GLP-friendly), supports USB and RS-232, and offers factory reset and IP54 protection.
