MULTIPARAMETER WATER QUALITY METER Multi 350i Multi-functional with the highest degree of accuracy, flexible, for universal use : the new Multi 350i. A Multi for all your requirements : pH, ORP, oxygen, conductivity, ISE, everything with a single pocket instrument. Up to 4 parameters including temperature can be measured and processed simultaneously if the new combined conductivity-oxygen sensor "ConOx" is used. Of course, the Multi 350i will also work with all the current single parameter sensors in the WTW range. Menu-controlled with backlit graphics display, with data logger and 1500 memory places. Including built-in top-quality NiMH rechargeable batteries and battery charger for up to 1500 h continuous measurements without recharging. ConOx ConOx: conductivity and oxygen measurement with fully automatic salinity correction. A slender and handy sensor for three parameters : conductivity, dissolved oxygen and temperature. The oxygen module can be easily removed and works according to the time-proven galvanic principle. Immediately ready for use, hardly any maintenance necessary, for all water analysis applications in laboratory and on site, especially for fish farming in combination with the armature A 325/S and protection SK 325. Including OxiCal® CX calibration vessel. The conductivity sensor features the time-proven 4- electrode system. If desired it can also be used without the oxygen module. Precise, insensitive to deposits and dirt, easy to clean – it is an ideal sensor for standard laboratory water and wastewater applications. Available with cable lengths 1.5 m, 3 m and 6 m. Multi-Parameter Probe MPP 350 An all-new Multi-Parameter Probe as the perfect probe for use with Multi 350i : With a diameter of only 1.6 in (41.5mm) and a length of 10.6 in (27 cm), this probe is usable in a wide range of application. Wherever simultaneous measurement of pH, dissolved oxygen and conductivity is required, this probe is the ideal supplement to Multi 350i. Suitable for measurements in lakes, rivers, seawater  and brackish water, in boreholes down to maximum depth of 82 ft (25 m), as well in groundwater and spring water. The special pH sensor SensoLyt® MPP-A (please order separately) for measurement in water provides reproducible measurement value, even at low conductivity levels. The new oxygen modules permit flow independent oxygen measurements. It provides for precise  oxygen determinations, even in stagnant waters. The conductivity measuring cell with proven 4-pole-measurement technology has a measuring range of 1 µS to 2 S. The MPP 350 is available with 6 different cable lengths up to 82 ft (25 m). Accessories include specialized calibration vessels and handy carrying case.
