All probes feature:
A rugged, all-in-one glass-free probe designed for measuring pH, electrical conductivity, ORP and temperature in diverse liquid environments
A multiparameter, steel-tipped probe ideal for penetrating semi-solid materials like cheese, fruits and pastes while measuring pH, EC, ORP and temperature with precision.
A compact, ISFET-based pH and temperature probe built for clean, inline or benchtop monitoring where fast, stable pH readings are essential.
Designed for high-viscosity or semi-solid samples, this steel-tipped probe measures pH and temperature in materials like gels, creams and fermenting foods.
Ultra-compact probe for measuring pH in micro-volumes (as small as 20 µL), perfect for cuvettes or tiny samples.
Access your data at your fingertips with the Sentron App. Connect multiple probes simultaneously to get multiparameter measurements across your entire operation in real time. With step-by-step guidance through calibration and setup, plus a 50-meter Bluetooth range, you can ensure a stable connection even at a distance. And you can even set up alerts whenever your measurements fall outside your set thresholds. Cloud-based storage and GPS tagging also add valuable context to your data while keeping it safe and accessible.
ISFET stands for Ion-Sensitive Field-Effect Transistor. An ISFET pH sensor is a solid-state device that measures the pH of a solution by detecting the hydrogen ion concentration in the solution. ISFET pH sensors are an alternative to traditional glass electrode pH sensors and are made of silicon-based material. Unlike glass electrode pH sensors, ISFET pH sensors do not contain glass and are not as fragile.
ISFET pH sensors work by measuring the voltage generated when hydrogen ions in the solution interact with the gate of the transistor. The gate of the transistor is coated with a thin layer of a sensitive material that reacts to changes in pH. When the gate interacts with the hydrogen ions in the solution, a voltage is generated that is proportional to the pH of the solution.
A pH probe is a device that measures the pH of a solution. It is made up of a sensor that is inserted into the solution and generates a voltage that is proportional to the pH of the solution.
pH probes work by measuring the voltage generated when the sensor interacts with the hydrogen ions in the solution. The voltage generated is proportional to the pH of the solution.
To store a pH probe, place it in a storage solution and store it in a cool, dry place.
