Systea S.p.A.

μMAC-1000 is an online portable analyzer of chemical parameters in water, available either in mono or sequential mutiparametric configuration, providing the highest level of analytical automation and compactness.

μMAC-1000 is the only available high sensitivity multiparametric portable and on-line analyzer using colorimetric approved methods.

The analyzer can measure many type of water samples on a wide range of applications, including sea water.

µMAC-Smart is a portable analyzer fully controlled by an integrated PC with integrated colour Touch Screen, specifically designed for at site monitoring of all water resources.

The analyzer is mounted in a robust and easy-to-transport plastic case including room for reagents and all other accessories. A reagent frame holds all reagent bottles and required solutions.

The analyzer is easy to be installed and it is designed for easy operations, the analyzer can be used at site after a quick training. It is delivered from factory fully tested and ready to use; reagent kits are available for all standard measurements. Results are stored inside the analyzer memory and can be downloaded through USB port .Analyzer start up and operations have never been easier! Just turn on  and insert the reagents: a simple software will guide the operator through all necessary steps.

SYSTEA proposes a series of submergible multiparametric in-situ probes for sequential automatic analysis of up to four nutrients or other chemical parameters in surface and sea water.

Our probes are specifically designed for unattended monitoring in oceanographic research, environmental protection and biological studies; the following models are available:

• NPA Pro
• WIZ probe.

The standard wet chemistries for nutrients analysis used in our in-situ probes are optimized to be used for unattended water quality monitoring in surface and sea water: NH3: fluorimetric OPA method PO4: Molibdate, Ascorbic acid colorimetric method NO3+NO2: UV reduction + NED, SAA colorimetric method NO2: NED, SAA colorimetric method.

Other chemical parameters available are: Silicates Total Phosphorous Total Nitrogen Total Dissolved Iron Sulphide.

Features and benefits

Up to four parameters sequentially measured Easy reagents replacement Low reagents consumption (about 200 microliters of each reagent for analysis) Reagents sealed bags refrigerated by surrounding water.

Advanced functionality Toxic waste is collected in a special bag placed inside the reagents compartment (NPA / DPA Pro) or outside the probe's body (WIZ) DI water is used to wash the hydraulic circuit and to perform a diluted measurement Self-cleaning filtration unit available as option.

Nutrients probe analyzer 

The NPA Pro has been designed to be best integrated in coastal buoys. The two cylinders can be easily placed on the buoy’s body holes and then simply anchored with chains or hooks or snaphooks.It is made of two different PVC cylinders:  the first one includes hydraulic and electronics components; the second one includes reagents, calibrant, DI water and waste bag. A single hydraulic connector with 10 tubing is used to connect the second cylinder to the first one. This multi-connector is provided with a valve to open it during functioning and to close it during transportation, to avoid reagent spillage.

Advanteges and benefits

• Two cylinders are more convenient/easy to deploy: the electronic compartment is never removed;
• The NPA Pro doesn't unbalances the buoy: the single body, if placed externally, can tilt the whole system that needs redistribution of buoyancy;
• If needed, the Cd column, may be placed just above the electronic compartment;
• The reagent compartment may be changed as a whole; its allowance is around 17 litres;
• Long lasting reagents quantity, expected reagent changeover every 45/60 days.
