WTW Handheld pH Meters
| Waterproof and submersible to IP66 and IP67 | |
| Operate on 4 AA batteries for up to 3000 hours | |
| Up to 3 point calibration with automatic buffer recognition | |
| All meters come as sets which include everything required for measurement, calibration and maintenance in a sturdy carrying case |
Model 315i is a basic meter for pH, mV and temperature measurements. Features include resolution to 0.01pH, automatic temperature compensation, and low battery warning. Comes as a complete set with meter, gel-filled combination electrode, buffer set, 3 M KCl, batteries, beaker, probe stand and carrying case.
Model 330i offers the same great features as above, but with resolution down to 0.001pH, auto-buffer recognition or selectable buffer values, time controlled datalogging of 500 GLP data sets and a calibration alarm.
Model 340i adds a bidirectional RS232 and analog interface and is capable of battery or 110V operation.
