Hayward Sense and Dispense, ORP and PH Sense, Chemistry Automation | HL-CHEM

Automate water chemistry with our integrated Sense and Dispense® option. Sense and Dispense automatically senses chlorine and pH levels and dispenses chlorine via a salt chlorination system or a liquid chlorine feed tank, and controls pH.

This is the HL-CHEM Chemistry Automation ORP and pH Sense with ORP Dispense.

Works with Hayward Automations Systems

Sense and Dispense is an optional add-on and works with the following Hayward Automations:

• ProLogic Automation
• AquaPlus Automation
• AquaRite Pro Salt Chlorination

Commercial Grade Sensors

Unlike laboratory-rated sensors, commercial-grade sensors are rugged and rated for large, high-demand commercial pools and outdoor conditions. Sense and Dispense® uses only commercial grade sensors.

Sense & Dispense, Chemistry Automation

This professional-grade ORP and pH Sense and Dispense technology was previously only available for commercial pools. Hayward now offers an economical approach, with the same level of accuracy, for residential pools. Unlike others on the market, Sense and Dispense uses a proportional feed algorithm that continuously tests the water, sampling pH and sanitizer activity, and adjusting chemical feeding on a basis proportional to the demand. Other approaches don’t sample the water often enough and release larger doses, which is far less effective and can create highs and lows similar to a manual approach.

Adding Sense and Dispense to your ProLogic®*, AquaPlus® or AquaRite® Pro is a fully integrated solution – not an additional box that resides on your pool pad – eliminating additional installation costs. It also provides a single source for status reporting and control.

Sense and Dispense consists of two kits. The first kit senses pH and ORP levels and dispenses a self-renewing supply of pure chlorine generated from salt. pH dispense can be
achieved using the second kit, which includes a manifold that connects to a CO2 tank. CO2 is highly effective in lowering pH.  With salt-chlorinated pools, pH tends to drift up. CO2 reduces pH to recommended levels by forming H2CO3 (carbonic acid), a safe acid that does not require handling. As an alternative to CO2, Sense and Dispense also supports the Stenner Pump acid feed system - a proven solution and approach to chemical delivery. It’s robust, safe and reliable.
