Handheld Multiparameter Meters Product Description

With its ability to measure pH, mV, oxygen, conductivity and ISE, the Multi 3500i, Handheld Multiparameter Meters are the perfect choice for all of your water, wastewater and environmental field measurement needs.  Like all WTW field instruments, the Mult 3500i, digital multiparameter meter is designed to stand up to the rigors of daily plant and field conditions while being accurate and easy to use.  The handheld multiparameter meter's bright backlit screen can display pH, oxygen, conductivity and temperature simultaneously.

Easy to use, the Multi 3500i, Handheld Multiparameter Meters feature a high resolution, high precision, simple, menu-driven user interface.  The digital multiparameter meter has a datalogger, memory for 1,800 data sets and a real-time clock that support good laboratory practice (GLP) requirements.  The Multi 3500i, handheld multiparemeter meters won't let you down with their built-in NiMH rechargeable battery for up to 500 hours of continuous measurements (AC adaptor included).  Combined with the MPP 350 multiparameter probe the digital multiparameter meter is ideal for environmental field measurements.  But the Multi 3500i, handheld multiparameter meters are also at home in your lab when used with the ConOx conductivity/oxygen sensor.  In addition, all the currently compatible WTW pH, combination ion specific, oxygen and conductivity sensors can be used to extend the usefulness of the handheld multiparameter meter.

MPP 350 Multiparameter Meter Probe
Wherever simultaneous measurement of dissolved oxygen, conductivity, and pH or ORP is required the MPP 350 is the probe or choice for the Multi 3500i, handheld multiparameter meters.  With a diameter of only 1.6 in (41.5 mm) and a length of 11.42 in (29 cm), this multiparameter meter probe is usable in a wide range of applications.  The Multiparameter Meter Probe is suitable for measurements in lakes, rivers, seawater and brackish water, and in monitoring or groundwater wells to a maximum depth of 330 ft. (100 m).  The special pH sensor SensoLyt® MPP-A, not included with MPP 350 multiparameter meter probe, provides reproducible measurement values in water, even at low conductivity levels.  The special ORP sensor SensoLyt® MPP-A Pt, not included with MPP 350 multiparameter meter probe, allows you to measure the ORP voltage of your sample.  For cable lengths greater than 20 ft. (6 m) a battery operated stirrer is included.  The conductivity measuring cell with WTW's proven 4-pole-measurement technology has a measuring range of 1 uS/cm to 2 S/cm.  The MPP 350 is available with several different cable lengths up to 330 ft (100 m).  Accessories include specialized calibration vessels.  Two field kits are available which include: a case, Multi 3500i handheld multiparameter meter, accessories and an MPP 350 multiparameter meter probe with either a 20 ft. (6 m) or 81 ft. (25 m) cable length.

ConOx: Conductivity and Oxygen Measurement with fully automatic Salinity Correction
The ConOx multiparameter meter probe is great for all water analysis applications in the field and in the lab.  The Multi 3500i handheld multiparameter meters use this slender and handy multiparameter meter probe to measure three parameters: conductivity, dissolved oxygen and temperature.  The multiparameter meter probe's oxygen module can be easily removed and works according to the time-proven galvanic principle.  Low-maintenance and ready for use any time you need it, the multiparameter meter probe's oxygen module also includes the OxiCal® CX calibration vessel.  The multiparameter meter probe's conductivity sensor features the time-proven 4-electrode system and may be used without the oxygen module.  Easy to clean, the multiparameter meter probe's conductivity sensor is capable of accurate measurements even when used in environments that would foul conventional electrodes.  The multiparameter meter probes are available with cable lengths 4.9 ft, 9.8 ft, 19.7 ft, 32.8 ft, 49.2 ft, 65.6 ft (1.5 m, 3 m, 6 m, 10 m, 15 m, 20 m).
