PreSens' Featured pH Measurement System for Perfusion Monitoring
The pH-4 mini is a fiber optic pH meter for simultaneous operation of up to 4 pH sensors. The matching pH sensors type HP5 & HP8 are based on a 2 mm optical fiber and optimized for physiological solutions. The pH meter is connected to a PC and controlled with a user-friendly software.
A polymer optical fiber (POF) is needed to transfer excitation light to the sensor and the sensor response back to the meter. We offer different versions for different meters depending on their optical connector type. A POF enables non-invasive and non-destructive measurements to be made from the outside through the wall of a transparent or slightly colored container. The POF with SMA connector is compatible with meters of the Fibox, OXY-1 SMA, OXY-1 WM,OXY mini and pH mini series, as well as the pCO2 mini. The POF with ST connector is compatible with meters of the Microx 4 and OXY-1 ST series. Different standard lengths are offered, e. g. 2.5 m, and fibers with connectors on one or both sides are available, depending on your adapter or sensor application.
A miniaturized optical pH sensor is attached to a color coded stick, which can be attached to flow-through cells of different size and shape, according to requirements. A polymer optical fiber connects the sensor inside the flow-through cell to the pH meter. The single-use T-cell of the FTC-SU-HP5-S is made of polycarbonate and all parts come beta-irradiated.
