Elite CTS Replacement Sensor (Pin or Cup)

This is a replacement sensor module for the Elite CTS tester. You can choose between the pin or cup sensor by selecting from the dropdown. The pin sensor is £20.28 excluding VAT. The cup sensor is £22.77 excluding VAT.

It is very easy to replace the sensor on your Elite pH 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 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.
