The IDS family keeps on expanding :

Two new Multi parameter sondes for depth measurement as well as pressure resistant digital plug head sensors and cable lengths up to 100 m open the door for enhanced measurements in the field: Profile measurement with depth readings, measurements over long distances – perfect tasks for IDS systems.

MPP 910 and 930 IDS – Smart Multiparameter Sondes

Universal Applications

Profile studies, bore holes, weirs, ground water, estuaries and sea water – a perfect task for the new MPP 910 IDS or MPP 930 IDS with the new IDS plug head sensors IDS for pH, conductivity and dissolved oxygen. This unique modular system based on the IDS technology helps to overcome almost any challenge when measuring electrochemical parameters in the field.

Smart Sensor Connection

Absolute highlights are the new, pressure resistant, waterproof, and tensile strength guaranteeing easy to lock connectors. This easily helps connecting one of the new intelligent plug head sensors to the digital multi parameter sonde but also connects them or the sonde with the new AS/IDS cables. Simply plug, lock with a “click” and you are done. They are waterproof up to 10 bars, and completely insensitive against sand and silt.



Secure Cables

With an ultimate strength of 300 N (corresponding about 30 kg) the thin Aramid® reinforced cables resist all loads during routine work and not only providing perfect data transfer but also secure the sondes against loss.
They are also characterized by a low weight and an excellent handling. They are available in lengths between 1.5 m and 100 m. From 25 m on they are delivered on a reel. Forthcoming a reel with sliding contact rings will be available which enables a simultaneous winding and readings on the meter. For this additional information will be made available.

Built-in Depth Measurement

Each MPP IDS has a temperature compensated, calibration-free, pressure sensor. Important note: The depth measurement with connected sensors will be done at the level of the sensor tips. It could also be used only for depth measurement without water quality sensors. The depth measurement will be taken at the height of the sensor itself. Coded plugs will be used in order to prevent the sonde connectors from flooding on the sonde socket board. If an input will be left open the meter gives a warning and blocks any measurement. The depth sensor is factory calibrated and maintenance free. The measurement starts at depth of at least 0,5 m and works with a resolution of 0.05 m down to 100 m. Manual correction for salinity is possible. The accuracy is given with ± 0.25 m.

MPP 910 IDS

Specifications

The MPP 910 IDS is a slender single input multiparameter sonde with built-in depth sensor. It measures with the new plug head sensors SensoLyt® 900-P, SensoLyt® ORP 900-P, TetraCon® 925-P or FDO® 925-P pH, ORP, conductivity or dissolved oxygen. Temperature is measured together with each parameter.

With its length of 50 cm and a 40 mmm diameter it is also suited for measurement in bore holes. Other applications are the dependency from depth of single parameters e.g. measurements at barrages or D.O. profiles in stagnant water. A weight with 500 g allows vertical submersing with low impact from flow. The total weight is ca. 850 g.

MPP 930 IDS

Specifications

The MPP 930 IDS is a multiparameter sonde for simultaneous profile measurement of up to three electrochemical parameters plus depth. Typical applications are limnological profile measurements but also other examinations in water bodies down to 100 m. It also uses the new plug head sensors SensoLyt® 900-P, SensoLyt® ORP 900-P, TetraCon® 925-P or FDO® 925-P pH, ORP, conductivity or dissolved oxygen. These could be measured in combinations of pH or ORP together with conductivity or dissolved oxygen. Of course, only one oxygen sensor can be connected at the same time. With a 70 mm diameter and a weight of 3 kg including weight it submerses perpendicular also when exposed to flow which can occur also in stagnant water. It is also working without sensors as pure depth sonde.

Portable meter: Multi 3430

For operation of the MPP IDS a Multi 3430 is necessary. A firmware update starting with V2.31 is required.
 
  • Display when connected a MPP 910 with pH electrode.
  • Display when connected a MPP 930 IDS with all sensors (pH, conductivity, D.O.)
  • Display when used as depth sensor.
     

All operational features of a Multi 3430 (memory capacity, data logging etc.) will be maintained when using a MPP IDS. The display will be extended by a depth reading; also the data strings include this new parameter. The CSV string also gives alternatively additionally D.O. saturation or concentration, depending on the parameter selected.

When connecting a MPP 910 IDS or 930 IDS all other channels will be locked. A measurement of 4 or 5 parameters at the same time is not possible. If not already available a Multi 3430 has to be ordered separately.

The firmware update for existing Multi 3430 can be downloaded from internet or uploaded to the meter by the CD-ROM supplied with the sonde.

Some Specifications
  • Brilliant color display for visual representation of parameters, allocated channels and additional information
  • Two USB interfaces (USB-A and UBS-B) for convenient data transfer to USB memory drive, selected printers or to PC, memory for 10,000 data sets.
  • Economic operation with rechargeable batteries
  • Firmware update via Internet
  • User administration for GLP/AQA
  • Waterproof according IP 66/67

Calibration

Easiest calibration: Connect the sensor with the cable from the delivery directly to the meter. Calibrate as usual, unplug the sensor, and connect it to the MPP – that’s it.
Advantage: when calibrating pH and conductivity only normal amounts of standard amounts are necessary, no extra calibration vessels. The optical D.O. sensor will be checked with its standard check vessel.

Competition

WTW does depth measurement since more than 25 years, the last product was the MPP 350 in combination with Multi 350i; the MPP 350 will be discontinued by end of 2013. The depth armatures TA-xx will be discontinued by end of 2012. WTW covers the market segment of portable spot measurement, the on-site short term data collection. All competitors for multiparameter and depth measurement are normally specialists for high-prized sondes for long term deployments and/or optical parameters as chlorophyll, blue green algae, fdom (fluorescent dissolved organic matter),turbidity etc. or have only simple systems (Hanna, Fisher). This fact can be perfectly utilized for offering IDS sondes. Important is also the fact that IDS is a the most flexible system in the market that covers all applications from field to laboratory with a variety of meters and sensors.
