Aim of the products:

Measure, in the field, parameters like water conductivity,

pH, dissolved oxygen, redox, turbidity



4/33

4

Typical research purposes

Determine conductivity

of water or

soil-water mix

Salinization problems of soils

Irrigation water quality

Determine plant stress



5/33

5

Typical researchpurposes Monitoring leaching processof salinized

soils in aridregions

When leaching a soil

salts are washed downby over-irrigating thatsoil with non-salinewater

Good drainage isessential

Monitor conductivity

of water

Working principles

Various principles

Multimeters and Multiparameter probefor pH, EC, Redox and O2

-All work with electrochemical probes

-Internationally standardizedprocedures

Turbidimeters

-Measure visibility in water by

determining how light is scatteredunder a 90

angle in a small sample

vial (ISO standardized)



11/33

11

Working principles

Various principles

Water level dataloggers (Diver; see thespecial Diver presentation for more info)

e+ WATER L

type

e+ OVERFLOW

-

Directly measures and logs water levelfluctuations in open water (WATER L)or sewers (OVERFLOW)

- Models with measuring ranges 0.5;1; 1.5 and 2 meters-

Can be combined with telemetry



12/33

12

Working principles

Various principles

Field equipment for determination of chemical wateror manure composition like Nitrachek, RQ flex, Test setfor well water, Manure test kit

-All work based on colorimetry

Chemicals react with reagents. Resulting colouris judged by eye (test set for well water) or by aphotometer (Nitrachek, RQ flex, Manure testkit)

Limitations of principle

Multimeters

pH, EC, O2

, Redox

with electrochemical probes

Drift of probes must be corrected regularly (calibration) Oxidation of plugs must be prevented; store dry !

Water level loggers e+ WATER L

and OVERFLOW types

Requires a thorough preparation (equipment selection,

software training)

Colorimeters

Reagents may react on unwanted parameters

Reagents may be insufficiently sensitive for parameter

Limited storage time of reagents

May be quite different from official lab methods
