Rosemount™ 550pH Single-Use Sensor
rosemount 550ph-single-use-sensor
Rosemount 550pH Sensor is designed to provide high measurement stability for Single-Use bioprocessing applications.
The sensor stability of <0.005 pH change per day enables users to do a one-point calibration at the start of the batch and operate for 30 days without any required maintenance or recalibration. Our patented wet storage technique enables a two-year shelf life as well as immediate sensor verification and calibration, eliminating the initial stabilization process.

Features

  • High measurement stability which leads to fewer one-point sensor standardizations
  • Shelf life up to two years from manufacturing date
  • Sensor begins measurement immediately, with no stabilization time needed to wet glass for a measurement
  • Ensure sensor functionality prior to filling the bioreactor with a true, one point standardization against a calibrated traceable storage solution.
  • Sensor installs into 1 inch barb fittings onto Single-Use bags
  • USP Class VI, ISO 10993, and ADI-free compliant wetted materials
  • Material selection based on lowest achievable extractables profiles (Extractables report done per BPOG guidelines available in July 2019 on Emerson online store: More information to come)
