Kill The Service Contract: What Happens When A Sensor Maintains Itself

Annual service agreements are often treated as fixed, unavoidable expenses in water utility budgets. However, these contracts are largely a byproduct of high-maintenance equipment that demands frequent intervention to correct drift, replace fouled membranes, and replenish reagents. When monitoring equipment is designed to minimize these points of failure, the fundamental economics of the service agreement change.

Integrating continuous, mechanical cleaning mechanisms keeps electrodes clear and maintains calibration stability over extended periods without human intervention. Eliminating standard wear items removes the need for routine technician visits. Instead of locking funds into recurring service plans, utilities can pivot to a shelf-spare model, holding a backup unit on-site and returning hardware for maintenance only when necessary. Rethink traditional maintenance strategies and evaluate whether your current contracts are truly necessary.
