Mono & Multi-Channel Water Controller

The EL200 is a durable and modular water quality controller designed to accommodate various probes for monitoring essential parameters, including pH, ORP, dissolved oxygen, conductivity, chlorine, turbidity, TSS, and temperature. Housed in a weatherproof enclosure, it is well-suited for both field and process applications. The system offers an intuitive touch-screen interface, versatile multi-channel capability, and options for both local and remote operation.
