The Rosemount Analytical 3800 pH sensor is designed for accuracy and stability in heat intensive applications, and are optimized for autoclaving and steam sterilization. Building on PERpH-X and AccuGlass technology, the 3800 sensors exhibit unparalleled stability after exposure to high temperature sterilization.

The PUR-senseTM reference electrode uses a silver-silver chloride sensor in combination with a new gelled potassium chloride electrolyte to provide a stable reference potential through the single proprietary ceramic reference junction. 3800 test data indicates the sensor drift is well within 0.1pH (0.02-0.07pH).

The proven stability of the 3800 sensors translates into less maintenance and more reliable measurements even after multi autoclaving cycles. 3800 models are at least 2 times more stable than any other pH sensor in this challenging application. All pH sensors were calibrated in buffer solution prior to drift measurements. Testing media for this test was cell-culture or simulated perfusion culture process.
