The pH minisensor PHF500-PK8 is composed of a black fiber-optic cable, ca. 2m in length with ST-plug for connection to the optical meter FireSting®-PRO. The pH sensing tip is located at the very end of the optical fiber and is fixed in a needle. The fragile 500µm sensor tip protrudes (5mm) unprotected from the needle and has to be protected from light and mechanical stress. Available for a defined pH range of pH 7-9, each packaging unit contains 2 pH minisensors. Perfectly suited for pH measurements in small volumes and for fast pH measurements.

pH range 7.0-9.0 This sensor is specified for the pH range 7.0-9.0. For detailed specifications, see the respective pdf file in the Downloads tab.

ST-connector. This connector is our standard sensor connector for sensor compatible PC-operated and handheld FireSting devices.

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.
