PH sensor 243216

temperaturecalibrationprocess

The Hamilton OneFerm pH sensor is a single use glass electrode for pH measurement. It retains the high accuracy performance of a glass electrode after gamma irradiation and dry storage. It is delivered as an integrated part of a single use container to provide ease of use. The OneFerm pH sensor is only available to integrators such as bag-, bioreactor- or downstream skid manufacturers.
