Model PHM28
the Radiometer ρΗΜ28 Meter
has many other applications for pH measurement, titration or control. It is low in cost but high in quality and stabil ity, and completely free of zero drift. With 0.02 pH reproducibility on a large mirrored and folded scale (0-10, 6-14 pH), it can be used for redox and dead stop end point titrations (Karl Fischer), and for external recorders. A matching control unit (Model TTT11) converts pHM28 to an automatic titrator or for pH control, and electrodes are available for many applications to match the convenient and integral electrode stand. There are many other features -ask for literature and prices.
