YSI TruLab® pH/ISE Benchtop Meter (1320 / 1320P)
The YSI TruLab® pH/ISE 1320 is a dual-channel benchtop meter for simultaneous measurement of pH, mV (ORP), ion-selective electrode (ISE), and temperature — the ideal laboratory instrument when you need ion concentration alongside pH with fully documented, GLP/AQA-compliant results. Up to 5-point pH and 7-point ISE calibration, AutoRead stability detection, a Continuous Monitoring Control (CMC) range check, and USB data export keep measurements accurate and traceable. Store up to 500 data sets manually or 5,000 automatically.
