SciCon Sensor Sanitization Test Protocol
Parker/Scilog DN 3023: SciCon Sanitization, 1.0 Molar NaOH @ 22 ºC and 50 ºC, 2 Hours
NOTE: Parker sensors are designed for disposable, single-use applications. However, with proper care, the
Parker sensors can be re-used repeatedly while maintaining good accurate and precision. If required, SciCon
sensors can be re-calibrated.
CAUTION: Do Not Exceed Maximum Pressure of 60 psi
Test Protocol: Six pre-calibrated (13.04 mS) SciCon Luer conductivity sensors were exposed 3 times to 1.0
molar NaOH for two hours each at 22 ºC (Group1) and at 50 ºC (Group 2). After each 2-hour exposure, the
sensors were flushed 3x with distilled water and inserted into a temperature controlled glove box. A solution was
then circulated through the sensors utilizing a peristaltic recirculation pump. The sensors were conductivity-tested
and temperature-tested at the indicated standard values. The conductivity standard of the solution was tested
using a NIST-traceable (YSI Model 30) conductivity meter. The temperature standard was measured using a
NIST traceable temperature thermometer. The sensor responses were tabulated. The original factory calibration
was maintained during the trials; no additional sensor calibrations were carried out before or during the trials. For
this test, SciCon sensors were randomly selected from Parker inventory.
