The pH/mV and ISE meter pH/ION 340i offer the highest degree of flexibility possible. For pH measurements the instrument can be calibrated manually or automatically and offers simultaneous display of pH and temperature. For measurements with ion-selective electrodes the pH/lON 340i offers concentration display in mg/l. Direct display in mV to ±999.9 mV in 0.1 mV steps; and to ±1999 mV in 1 mV steps.
Even in these higher ranges the concentration is calculated from a mV resolution of 0.1 mV. Calibration is carried out with up to three standards (selected from 16 standards in the range of 0.01 to 1000 mg/l).
The instrument can be used in-the-lab or in-the-field, operating on either AC power or rechargeable battery for up to 1500 hours, with convenient “LoBat” warning.
Lightweight and compact, these robust meters are both waterproof and submersible to IP 66/67.
The built-in data logger for up to 500 measurements together with GLP calibration protocol offer a comprehensive system for documenting results. With analog or digital data transfer (RS 232), automatic recognition of stable measurements (AutoRead), electrode evaluation and calibration interval monitoring functions ensure reproducible and comprehensible measurements.
