Smart Trek Vacuum Sensor - Single Port. H2O-Smartrek Monitoring System The H2O-Smartrek system is a highly efficient solution providing accurate intel on your tubing system. By using different sensors installed throughout your sugar bush, you can quickly find out where leaks are, even the smallest ones, and act promptly to maintain a high vacuum level at the tap. This system can also be used to start/stop pumps, and to monitor sap levels in tanks. We have been using the H2O system in our own woods for over 3 years now.
