Every pH measurement is temperature sensitive. For accurate pH measurement it used to be necessary to use a separate temperature probe. It was virtually impossible to adequately temperature compensate small samples, surface measurements, or difficult samples requiring a Sure-Flow(tm) electrode. Now all these problems are solved with the NEW! line of PerpHecT pH meters featuring digital LogR(tm) technology.
Only PerpHecT pH meters allow for direct temperature measurement and temperature compensation from your pH electrode. Orion Research's patented digital LogR technology makes it all possible with the simultaneous measurement of pH and temperature, using most standard glass pH electrodes. And for the maximum temperature compensation accuracy and precision, Orion Research offers PerpHecT and PerpHecT ROSS® electrodes -- optimized for digital LogR temperature compensation -- in a wide range of electrode designs. PerpHecT electrodes are available for all popular pH applications.
pH measurements are temperature sensitive in two ways: slope change (Nernstian) and offset hysteresis. Only PerpHecT meters combined with PerpHecT ROSS electrodes can provide ultra-precise temperature compensation for both types of temperature effects. The PerpHecT meter, PerpHecT ROSS electrode combination is the ultimate choice in pH measurement accuracy and stability.
PerpHecT electrodes are the highest quality and performance pH electrodes available. These electrodes are manufactured to tighter tolerances than our standard pH electrodes and when combined with our PerpHecT digital LogR meters give the Customer "PerpHecT" temperature-compensated pH measurements.
PerpHecT electrodes come in two categories. PerpHecT ROSS and conventional (silver/silver chloride) PerpHecT pH. Sizes and shapes cover the range of pH applications, from research grade laboratory electrodes to semi-micro, flat surface and Sure-Flow junction electrodes. All have BNC connectors.
PerpHecT ROSS electrodes offer the same stable, fast results as the premium ROSS line of electrodes regardless of sample temperature or composition, but with even greater LogR temperature compensation performance. The silver-free internal fill solution minimizes junction potential, so the PerpHecT ROSS electrodes can be used in any samples where maximum accuracy and precision are required. Only PerpHecT ROSS electrodes and PerpHecT LogR meters automatically compensate measurements for both Eo and slope temperature effects for optimum performance.
