The MATi 1 has all it takes to perform 59 water determinations fully automatically and includes all necessary accessories and sensors.

It is a ready to use system that fulfils many requirements.

It comes with full water analysis, quick aliquoting device and is PC -controlled.

The water analysis involves the determination of alkalinity and water hardness by means fan automated system consisting of an 815 Robotic USB Sample Processor XL in combination with an 836 Titrando.

The Aquatrode Plus is used as the indicator electrode for the alkalinity determination; the water hardness titration is indicated by Ca ISE combined with the reference system of the Aquatrode Plus.

The conductivity measurement is carried out with the 712 Conductometer and a conductivity cell that is installed on the second tower.

The 836 Titrando evaluates the signal supplied by the conductivity cell.

The standard rack used accommodates 59 beakers with a volume of 120 ml.

A propeller stirrer stirs the samples.

The new overflow burette transfers the sample to the external titration vessel using the built in pumps of the 815 Robotic USB Sample ProcessorXL.

After the titration the membrane pumps of the Robotic USB Sample Processor XL guarantee efficient aspiration of the spent solution and through rinsing of the titration equipment.
