Sentron has several series of Isfet pH probes with different tip designs to cover applications in liquids, semisolids, viscous solutions and more
All probes have ESD protection, can be stored dry and are easy to maintain.
One of the series is the Hot-Line probe, which is a complete new range of high temperature Isfet pH probes, designed for use in demanding applications.
These probes incorporate a non-flow, solid state reference with a large area PTFE diaphragm.
Using heat and chemical resistant materials as well as high temperature resistant, chemically stable KCl reference gel, these probes function reliably at high temperatures up to 105C and in contact with more aggressive chemicals.
In this series it offers three different probe designs:.
Conefet conical probe facilitates measurements in viscous or sticky samples.
Surfet probe, Isfet sensor and reference junction mounted on the distal end, makes direct measurement on flat surfaces quick and easy.
Cupfet probe, very suitable for general pH testing, the cutout tip design also allows testing of very small sample volumes.
Lancefet probe, the pointed stainless steel tip allows easy penetration in dense, very viscous samples and semi-solids.
This probe is also available with a handle to ensure a good grip.
Our other probe line is Stream-Line probes.
These probes use a flowing reference with thickened KCl solution.
This reference provides a constant liquid flow that ensures stable readings while preventing junction fouling.
Although suitable for general pH testing, these probes (Conefet and Surfet) are ideal for low conductive and pure water applications as well as highly concentrated or polluting samples.
In this series we have the Conefet and Surfet tip models.
