E+H Digital pH sensor Orbipac CPF81D-7LH11 Memosens compact electrode
Orbipac CPF81D is the digital, simple solution for harsh environments. It measures reliably and accurately even in fibrous media and at high flow rates. With its integrated assembly, the electrode saves space and time during flow or immersion installation. Thanks to Memosens digital technology, CPF81D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
