Conductivity meter, Dimm KDI-A2

P Dimm — KDI-A2

The portable conductivity meter Dimm reference KDI-A2 (article code ART098458) is a measurement instrument for water-quality control. Accurate, compact and easy to use, it enables reliable monitoring of water parameters in domestic treatment, swimming pool, aquarium, industry or laboratory. It gives a fast, dependable answer whenever the quality of the water needs to be checked.

Measuring principle

The conductivity meter measures the electrical conductivity of the water, directly linked to the dissolved-salt content (TDS). The immediate reading indicates mineralisation, the efficiency of a softener or reverse-osmosis unit and the quality of the produced water. It is an essential everyday tool for anyone operating a softener or an osmosis unit.

Features

Supplied ready to use, the portable conductivity meter Dimm combines reliable electronics with immediate handling. It offers a clear reading and good repeatability. The associated consumables (reagents, cuvettes, calibration solutions, electrodes) are available separately in the DIMM catalogue to guarantee accuracy over time. The range covers all the usual water parameters, so you can build a complete testing kit around one or several instruments sharing the same consumables.

Applications

Control of drinking water, pool and spa water, aquarium water (fresh and marine), monitoring of softeners and reverse-osmosis units, industrial and food processes, laboratories and design offices. Regular parameter control guarantees compliant water, protects installations and optimises reagent and salt consumption. Monitoring the key parameters — hardness (TH), alkalinity (TAC), pH, chlorine, iron, nitrates, conductivity — makes it possible to anticipate scaling, corrosion or contamination and to precisely adjust treatments upstream and downstream.

Use and maintenance

The device is used on a taken sample (or online for the Testomat). Reaction times should be respected, cuvettes/electrodes cleaned after use and the instrument periodically calibrated with the dedicated solutions. Storage away from humidity and timely replacement of batteries/reagents as recommended guarantee lastingly reliable measurements. For professional use, keeping a measurement logbook is recommended to detect any drift and to demonstrate water compliance to customers or authorities.

Advantages

Compared with visual methods (test strips, disc comparators), this instrument provides a numerical, objective and reproducible reading that limits judgement errors and documents monitoring. Its speed allows more frequent checks without extra labour cost, while the availability of the dedicated reagents and solutions guarantees reliable results over time. It is the ideal tool to validate a treatment, diagnose a drift or reassure a customer about their water quality.

Good to know

The accuracy of a measurement depends as much on the device as on following the protocol: representative sample, clean cuvette, exact reagent dosing and respected reaction time. Periodic calibration with the reference solutions maintains accuracy. Store reagents away from light and heat and check their expiry date. In case of unexpected values, repeat the measurement on a new sample before concluding.
