Waterproof pHTestr 1
One of the benefits in selecting the Waterproof ph tester is that you can now replace the electrode whenever needed keeping the body tester intact. When the tester fails to calibrate, gives fluctuating readings in buffers or shows error messages ‘E2’ or ‘OR’ in a buffer and the procedures in the maintenance section do not help, you need to change the electrode.
With dry hands firmly grip the ribbed collar and slowly twist the body counter clockwise until it is completely removed. Save both the electrode module collar and O ring inside for later use. Pull the old electrode module straight out from the bottom of the tester. Remove cap from the electrode and press theON/OFF button to switch Testr on. Dip the electrode 1/2" to 1" into the test solution. Stir once and let the reading stabilize. Note the pH or press HOLD/ CON button tofreeze the reading. Press HOLD/CON again to release the reading. Press ON/OFF to turn off Testr. If you do not press a button for 8.5 minutes the Testr will automatically shut off to conserve batteries.
