By taking a serious look at all applications, we keep entering into new innovations in our semiconductor labproduction facility. Soon we will launch sensors for EC and ORP, with which great multisensor solutions for e.g. water monitoring can be provided. Additionally, we’re looking forward to end the R&D on ion-selective sensors.
Multisensor probe for monitoring multiple parameters simultaneously
For all applications we constantly seek innovations in our semiconductor labfactory. Soon we will launch sensors for EC and ORP. These can provide great multi-sensor solutions for, e.g., water monitoring. Imagine: all parameters to be monitored using one and the same probe! Additionally, we’re looking forward to finalize the R&D on ion-selective sensors.
EC: Electrical Conductivity
The EC is the measure of a material’s ability to allow the transport of an electric charge. This knowledge is important for water-quality monitoring in public water supplies, in hospitals, in boiler water and in industries which depend on water quality such as horticulture and breweries.
Low conductivities are expected for pure water applications like aquaria, household, drinking water and rivers. On the other side, high conductivities are expected for industries like irrigation, greenhouses and manure.
ORP: Oxidation / Reduction Potential
The ORP is the measure of the tendency of aqueous solutions, or any other chemical species, to either acquire electrons from an electrode and be reduced thereby, or to lose electrons to an electrode and be oxidized thereby. This knowledge is important for water-quality monitoring in hydroponics, aquaria, swimming pools, as well as environmental and wastewater sampling. E.g. ORP is an indicator of micro-organism inactivation in a swimming pool or spa pool.
High ORP values (positive potentials) are expected for aerated surface water, rivers, lakes, oceans, rainwater and acid mine water. Low ORP values (negative potentials) are expected in places with limitations in air supply such as submerged soils, swamps and marine sediments.
We started innovative developments on CHEMFET, ion-selective, sensors that have a membrane mixture suitable for detection of different ions based on the ISFET technology. Selectivity is based on proprietary modifications with several polymer matrix configurations. Nitrate (NO3–), Ammonium (NH4+) and Potassium (K+) are currently in development.
