Rinse the sensor in clean water, wipe with a cotton swab moistened with clean water (not DI water), and then re-rinse with clean water. Insert the ORP probe directly into the pouch, and let the probe sit in the calibration solution until the readings stabilize (small movement from one reading to the next is normal). 1. Switching the device to I2C mode after calibration will not affect the stored calibration. Use the ORP Sensor to measure the oxidizing ability of chlorine in swimming pools or to determine when the equivalence point has been reached in an oxidation-reduction reaction. In 6051010 and Quatro cables, the sensors installed in port 1 and port 2 use the reference from the sensor installed in port 1 only. The ORP solution should include a chart of solution values per temperature. Find creative lab ideas using Vernier sensors. YSI, a Xylem brand's Post YSI, a Xylem brand 4,322 followers 9mo If readings continue to change after re-calibration, try a new Zobell solution or consult manufacturer.

For best results when using the ORP sensor with a drop counter, add drops at a rate of one per two seconds. By examining these data, or performing a second derivative (also shown) or Gran plot, the equivalence point of the titration can easily be determined. However, a new ORP sensor may be capable of holding its calibration for several days. Remember, though: in many process conditions, auto-calibration may not work. If good pH and/or ORP response is still not restored, perform the following additional procedure: 1. 2 Follow the Calibration Wizard in the software or on the Con TROLL PRO. d.
