The TrolMaster EC & Temperature probes offer accurate and reliable monitoring of both the EC and temperature levels of the water being tracked by the Aqua-x. The PCT-2 probe, a commercially rated device, connects to the Aqua-X via the AMP-2 / AMP-3. It is designed to be placed in a water tank and features a threaded body with PCT-2 threads, allowing it to be easily installed into standard 3/4” PVC tee fittings.
