For liquids with little ionic activity, the SE 557 refillable pH sensor with Memosens digital technology is the perfect instrument. It is also self-cleaning, thanks to the pressurization of the glass body of this refillable sensor. Accurate temperature compensation for the process is provided by an integrated NTC 30K temperature element. This pH sensor is extremely accurate thanks to the SE 557 and its twin ceramic connections. This sensor is also available in analog form.
