A scalable process transmitter architecture includes a unitized sensor module and an optional scalable transmitter. The improvement on this process comprises replacing the sodium hydroxide with a hydroxide selected from the group consisting of ammonium hydroxide, alkali metal hydroxides other than sodium hydroxide, and alkaline earth metal hydroxides to reduce the viscosity of the reactive heavy components. The stabilizer is included with the mole number of two to twelve times larger than the total mole number of the compound.
