Dear sirs,

I'm looking for some special sensors, working in the following
conditions: about 200ºC of temperature, and about 200 kg/cm2 of
pressure, in a water/steam system. We need to measure the following
items: oxygen, water-solved hydrogen, pH, conductivity, potential and
elecrochemical noise.

I would be very grateful if you could send me information about this
subject.

Mrs. Eulalia Ferrando
