The pH/mV and ionmeter pH/ION 340i offers 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.
Of course, 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).
Operating on either line power or rechargeable battery for up to 1500 hours with “LoBat” warning means that the instrument can be used in the Lab or in the field.
Lightweight an compact, these impact meters are IP 66 (hose proof) and IP 67 (submersible).
The built-in datalogger for up to 500 measurements together with GLP calibration protocol offers a comprehensive documentation of the 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.
