The insertable pH miniprobe PHIMP500-PK6.5 is composed of a black fiber-optic cable, ca. 1m in length with ST-plug for connection to the optical meter FireSting®-PRO. The pH sensing tip is located at the very end of a bare optical fiber. The fragile 500µm sensor tip comes without optical isolation and has to be protected from light and mechanical stress. Available for a defined pH range of pH 5.5-7.5, each packaging unit contains 2 pH insertable miniprobes. Perfectly suited for pH measurements in semi-solid samples, for fast pH measurements and for integration into custom housings. The miniprobe is delivered with an intravenous cannula for insertion into semi-solid samples.

pH range 5.5-7.5 This sensor is specified for the pH range 5.5-7.5. For detailed specifications, see the respective pdf file in the Downloads tab.

Bare polymeric optical fiber. The bare polymeric fiber is more robust than the optical fiber of our standard bare fiber sensors. The sensor comes without sensor housing, but is delivered with a compatible I.V. cannula for protected insertion into semi-solid samples.

ST-connector. This connector is our standard sensor connector for sensor compatible FireSting devices.

Star sensor. This sensor is one of the world's best or only solutions in a certain application area, featuring for example a very fast response time, solvent resistance or a unique sensor format.

Easy calibration. Calibration of the pH sensors is performed at pH 2 and pH 11 using our easy-to-use calibration capsules (PHCAL2 and PHCAL11). For detailed calibration recommendations, please refer to the manual in the downloads tab.
