Elite ORP Tester Operating Instructions
HOLD Function
This feature helps to freeze the display for a delayed observation.
1. Press
button to freeze the measurement. 2. Press
again to release the measurement.
Sensor Maintenance
1. Rinse the sensor with sensor storage solution after each measurement. Care has to be taken not to damage the
sensor’s glass electrode.
2. In aggressive chemicals, dirty or viscous solutions, and solutions with heavy metals or proteins, take readings
quickly and rinse electrode immediately afterward.
3. If possible, keep a small piece of paper or sponge in the sensor cap – moistened with clean water or electrode
storage solution (NOT de-ionized water) – and close the cap over the sensor.
Sensor Replacement
Replace the sensor module at the fraction of the cost of a new tester. When the tester fails to calibrate or gives
fluctuating readings in calibration standards, need to change the electrode.
1. With dry hands, grip the ring with sensor facing you. Twist the ring clockwise. Save the ring for later use.
2. Pull the old sensor module away from the tester.
3. Align the four tabs on the new module so that they match the four slots on the tester.
4. Gently push the module onto the slots to sit it in position. Push the smaller O-ring fully onto the new sensor
module. Push the other O-ring over the module and thread it into place by firmly twisting counter clockwise.
Note:
It is necessary that recalibrate the tester prior to measurement after a sensor replacement.
