VIKING-PH500 Laboratory pH/mV Meter
Includes: pH composit electrode, Temperature probe, pH standard solution (4.01, 7.00, 10.01)
Overview — VIKING-PH500 laboratory pH/mV meter
VIKING-PH500 pH/mV meter pairs a 7″ touchscreen with high-accuracy electrochemistry: ±0.002 pH accuracy, 0.001 pH resolution and 1–6-point calibration. Intelligent workflows (user/calibration/method/data management), ATC/MTC and GLP storage (1000 groups) streamline routine QA and R&D measurements.
0.001 pH resolution
±0.002 pH accuracy
ATC/MTC temperature compensation
- Multi-reading: auto-read (fast/medium/slow), timed and continuous
- Reading prompts: Reading / Stable / Locked; Auto-hold endpoint
- Automatic electrode diagnosis (slope & offset); slope limit; calibration reminder
Key features
