Due to its small outer dimensions pH-1 SMA HP5 can be set up almost anywhere. It is compatible with non-invasive sensors, dipping probes and flow-through cells of type HP5 & HP8 (measurement range pH 5.5 - 8.5). pH-1 SMA HP5 has temperature compensation, so even in environments with changing temperatures precise pH measurements can be performed. The optical pH sensor can directly be integrated in bioreactors and cultivation vessels, and are read out with pH-1 SMA HP5 non-invasively from the outside. It is not necessary to open the vessel or take samples for measurements, so there is no risk of contamination. This USB-powered pH meter is operated with the PreSens Measurement Studio 2 software, which enables simultaneous control of several PreSens pH, O₂ and CO₂ devices, so measurement networks can be set up. With numerous features, the software makes the pH-1 SMA HP5 applicable in almost any application where precise pH measurements are needed.

A polymer optical fiber (POF) is needed to transfer excitation light to single-use flow-through cells (FTC-SU) or sensor sticks (SST) and the signal response back to the meter. For our FTC-SU and SST these special POFs show tight fitting fibers to ensure reliable non-invasive and non-destructive measurements. They are available in two different lengths (2.5 or 5 m) for all meters with an SMA connector as e. g. Fibox, OXY-SMA, OXY mini and pH-SMA series, as well as the CO2-SMA series.

The FTC-SU-HP5-US consists of a miniaturized optical pH sensor on a color coded stick, which is attached to a single-use T-cell. The sensor stick can be mounted on flow-through cells of different size and shape, according to requirements. The sensor inside the FTC is connected to the pH meter via polymer optical fiber and allows contactless measurements in perfusion systems. The FTC-SU-HP5-US is made of polycarbonate.
