What’s next?
By taking a serious look at all applications, we keep entering into new innovations in our semiconductor production facility. Recently we launched the sensors for EC and ORP, with which great multisensor solutions for e.g. water monitoring can be provided.
Additionally, we continue our R&D on ion-selective membranes for the ISFET sensors. Additionally, we are working on new MEMS – for even smaller pressure sensors than we already have.
Ion-selective sensors
Sentron is working on innovative developments on 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.
It’s all about sensors
Besides the wireless and durable pH probe product line, you can also reach out to us for any customized sensor integration into your own product.
ISFET (Ion Sensitive Field Effect Transistor) pH sensor
The non-glass ISFET (Ion Sensitive Field Effect Transistor) pH sensor is one of the sensors that we produce in our semiconductor production facility. It is robust and does not require wet storage. This makes it well suited for, e.g., agriculture, water environment, food and other industrial applications. Our ISFET assemblies are used successfully in the market of FDA approved and CE certificated medical devices for the medical application in gastro-enterology.

Contract development
Full wheatstone bridge pressure sensors
In our facility we also produce the advanced miniature piezo resistive sensor that is equipped with a full Wheatstone bridge for differential pressure measurements: thus, no influence due to atmospheric changes. The narrow dimensions of this pressure sensor make it ideally suited for medical applications. Our pressure sensor assemblies are already on the market in medical devices for cardiology, as well as for neurology and urology catheters.
4-electrode conductivity sensor for EC
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.
We produce the EC sensor in our own foundry. There are many applications where it would be beneficial to measure both pH and electrical conductivity. Some examples include:
- Agriculture: In agriculture, measuring the pH and electrical conductivity of soil can help farmers determine the appropriate amount of fertilizer to apply to their crops.
- Aquaculture: In aquaculture, measuring the pH and electrical conductivity of water can help maintain proper conditions for fish and other aquatic organisms.
- Industrial processes: In various industrial processes, measuring the pH and electrical conductivity of liquids can help monitor the quality of products and ensure consistent production.
- Environmental monitoring: In environmental monitoring, measuring the pH and electrical conductivity of water can help identify pollution and monitor the health of aquatic ecosystems.
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 and greenhouses.
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 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.
Measuring pH and oxidation-reduction potential (ORP) together can provide valuable information in a variety of applications. Here are a few examples:
- Water treatment: In water treatment, measuring pH and ORP can help determine the effectiveness of water treatment processes and ensure that the water is safe for consumption.
- Chemical manufacturing: In chemical manufacturing, measuring pH and ORP can help monitor the quality of products and optimize production processes.
- Environmental monitoring: In environmental monitoring, measuring pH and ORP can help identify pollution and monitor the health of aquatic ecosystems.
- Food and beverage production: In food and beverage production, measuring pH and ORP can help ensure the quality and safety of products.
High ORP values (positive potentials) are expected for aerated surface water, rivers, lakes, oceans and rainwater. Low ORP values (negative potentials) are expected in places with limitations in air supply such as submerged soils, swamps and marine sediments.
Multiple parameter monitoring with one single device
Imagine, all parameters to be monitored using one single device. It is possible with the pH/EC/ORP/T probes, see our shop.
Measuring pH, electrical conductivity (EC) , and oxidation-reduction potential (ORP) together can provide valuable information in a variety of applications. Here are a few examples:
- Water treatment: In water treatment, measuring pH, electrical conductivity, and ORP can help determine the effectiveness of water treatment processes and ensure that the water is safe for consumption.
- Chemical manufacturing: In chemical manufacturing, measuring pH, electrical conductivity, and ORP can help monitor the quality of products and optimize production processes.
- Environmental monitoring: In environmental monitoring, measuring pH, electrical conductivity, and ORP can help identify pollution and monitor the health of aquatic ecosystems.
- Aquaculture: In aquaculture, measuring pH, electrical conductivity, and ORP can help maintain proper conditions for fish and other aquatic organisms.
- Food and beverage production: In food and beverage production, measuring pH, electrical conductivity, and ORP can help ensure the quality and safety of products.
The EC and ORP are available as extra parameters in the wireless ISFET pH probe product line. This means that all three parameters can be measured with high precision and accuracy in one single device. This would make it a versatile and convenient tool for various applications, reducing the need for multiple probes and devices.
Additionally, the Sentron app provides user-friendly software and data management features that make it easy for users to record, analyze, and share their data.
The probes are reliable and durable as they can be easily renewed with just the replaceable sensor part. This is particularly beneficial for users who require frequent use and rigorous testing conditions.
