Every sample another probe
Every laboratory is different, and so are the vials, tubes and cell culture flasks for sample preparations. For this reason we have several variants of the probes: one is the general cone-shaped probe for use in beakers, erlenmeyer flasks etc. For small vials and tubes the MicroFET is more suitable with its 3mm diameter and 110 mm length barrel. See for the specifications of all variants our leaflet.

Look no further: we have the laboratory package. This complete benchtop package includes everything you need for wireless, durable pH monitoring in the laboratory. The tablet, held by a universal holder, provides easy use and visualization of the app on your lab table. The package contains a buffer solution set so you can start immediately with your pH measurements.
What’s next?
By taking a serious look at all applications, we keep entering into new innovations in our semiconductor production 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.
Multiple parameter monitoring with one single device
Soon we will launch sensors for EC and ORP. Imagine, all parameters to be monitored using one single device!
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 will become available as extra parameters in the 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.
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.
As we will produce the EC sensor in our own foundry, we will combine the EC sensor with the ISFET pH sensor into one single device. 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.
As we will produce the sensors in our own foundry, we will combine the ORP parameter with the ISFET pH sensor into one single device. 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.
Ion-Selective Sensors
We started 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.

Whether it’s in the laboratory, in the field, or in industrial applications, the ability to measure pH accurately is essential. pH is a critical parameter in various industries, including agriculture, environmental monitoring, food and beverage production, and pharmaceuticals. Thus, it’s vital to have a reliable and accurate pH measurement tool that can provide fast and precise readings.
One of the most innovative and advanced pH measurement tools available today is the ISFET pH meter for laboratory use. ISFET stands for Ion-Sensitive Field-Effect Transistor, which is a type of pH sensor that offers exceptional performance compared to traditional pH measurement methods.
In this article, we’ll take an in-depth look at the ISFET pH meter for laboratory use, how it works, its advantages, and why it’s the best choice for scientific research and industrial applications.
What is an ISFET pH meter for laboratory use?
An ISFET pH meter for laboratory use is a new generation of pH measurement tool that uses a solid-state pH sensor instead of a glass electrode sensor. The ISFET sensor comprises a thin layer of silicon oxide, which acts as an insulator and a pH-sensitive gate. When the pH-sensitive gate comes into contact with a sample solution, it responds to changes in pH by changing the surface charge of the gate. The change in surface charge produces a measurable change in the electric field, which is proportional to the pH of the sample solution.
Advantages of ISFET pH meter for laboratory use:
Compared to traditional glass electrode pH meters, ISFET pH meters offer several advantages, including:
Fast and Accurate Measurements: ISFET pH meters provide rapid and precise pH measurements, making them ideal for time-sensitive experiments and industrial processes.
Wide pH Range: ISFET pH meters have a wide pH range, making them suitable for various applications.
Resistance to Electrolytes: Unlike glass electrode pH meters, ISFET pH meters are resistant to changes in the electrolyte concentration of the sample solution, which can interfere with the accuracy of measurements.
Durability: ISFET pH sensors are more durable than traditional glass electrodes and are less prone to breakage.
Easy to Clean: ISFET pH sensors are easy to clean, making them ideal for use in applications where cleanliness is critical, such as in the food and pharmaceutical industries.
