Elite PCTS (PCTS) Replacement Sensor

This is a replacement sensor module for the Elite PCTS tester. It is very easy to replace the sensor on your Elite PCTS once it shows signs of calibration failure or fluctuating readings. No need to buy a whole new tester, just purchase a sensor at a much lower cost.

Replacing a sensor

• Ensure you have dry hands.
• Hold onto the ring with the pH / CTS sensor facing you. Twist the ring clockwise. Set the ring aside for later.
• Remove the old sensor module from the tester by gently pulling it away.
• Match the four slots on the tester with the four tabs on the new sensor module and gently push the module into the slots.
• 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.
• Your tester will now require calibration before use. You will have received a full instruction booklet with your tester that you can consult if need be.
