Overview

Sentron pH meters and ISFET probes using the ISFET technology
Sentron has developed a comprehensive line of quality meters and probes for glass-free pH measurement. The SI line of meters and probes is created around Sentron's propriatary ISFET pH sensor that offers accurate and reliable pH measurement for demanding applications.

Sentron SI600 pH meter
The SI600 meter contains extensive features required for high-end pH measurements and is designed to work seamlessly with Sentron’s SI series probes.

Sentron ConeFET pH probe
The ConeFET pH probe is a general purpose probe with a conical tip designed to be used for a wide range of pH sensing applications. For example, the ConeFET can be used in the laboratory for sampling of liquids, with a wide range of viscosities, in a flask or beaker. It is also well suited for use in the field or in industry. Applications for which Sentron’s customers use ConeFET probes include laboratory testing, environmental water quality monitoring, food quality monitoring and monitoring of pH in pharmaceutical / nutritional processes.

Sentron CupFET pH probe
The CupFET pH probe is especially designed for measurement of small volume samples. Measurements can be performed by placing as little as a single droplet of liquid directly onto the probe’s cup shaped tip. Sentron’s customers use the CupFET probes to directly measure the pH of fruit in the field by pressing a droplet of juice onto the probe tip. Similarly, in laboratories or industrial processes, they pipet droplets directly onto the CupFET probe tip to measure the pH of samples.

Sentron LanceFET pH probes
The LanceFET pH probe, thanks to its stainless steel tip, is perfectly suited for piercing applications. Two LanceFET versions are available: one with a regular slim handle for medium strength piercing applications, and one with a thick handle that can be used in those situations where more force is required. Applications for which Sentron’s costumers use the LanceFET pH probes include food quality monitoring (e.g. meat, hard cheese and fruits) and testing of pastes and semi solids in chemical processes.

Sentron MiniFET pH probe
The MiniFET pH probe is a compact probe designed for stand alone integration into a process or placement in the field. Its short barrel allows it to be mounted without much protrusion from an apparatus or in situations where a low profile is required. Applications for which Sentron’s customers use the MiniFET pH probe include monitoring of (bio) chemical processes and water quality monitoring.

Sentron MicroFET pH probe
The MicroFET pH probe is a probe with a barrel diameter of just 3 mm (0.1”), ideally suited for pH measurement in narrow vials. Thanks to it’s barrel length of 110 mm (4.3”) it can also reach to the bottom of long vials and test tubes. Applications for which Sentron’s customers use the MicroFET pH probe include laboratory testing, monitoring of DNA sequencing and monitoring of biochemical reactions.
