Robust Meters & Non-Glass Probes

Sentron pH Meters & ISFET Probes

Robust and Intuitive Portable pH Meters and Probes

High end reliable and robust meter and probes for the measurement of pH plus temperature in a wide range of applications including food, healthcare and environmental services. Light weight, compact body and ergonomic design allows for easy use anywhere in the field or on the production line, whilst the rubber boot provides shock proof protection. The design of the unit is also stable enough for user friendly use in the laboratory.
A full range of ISFET probes allows for a wide variety of applications of pH & temperature measurement to be taken in samples such as liquids, food products, test tubes and mini-cuvettes. ISFET probes are manufactured from high quality plastic such as PEEK, ABS & PVC with no glass components, meaning probes can be used anywhere in the production or healthcare industries.
