Product Description

Automated water quality solution for pools, spas, water parks and more, world-wide.

The CAT 2000 continuously monitors pH and sanitizer activity, constantly adjusting the feeding of chemicals on a basis proportional to the demand. The results include the elimination of “human error”, accurate and reliable maintenance of chemical levels twenty-four hours a day, compliance with Health Department chemistry standards, reduced burden on operating staff, and a reduction of chemical usage and costs. 

Enclosed in the packaging, you should find all of the following:

• (1) CAT 2000 Water Chemistry Controller
• (1) Professional Series pH Sensor with 24” Cable and BNC Connector
• (1) Professional Series ORP Sensor with 24” Cable and BNC Connector
• (2) BNC Connector Protective Covers (Remove to Connect Sensors)
• (2) Sensor Storage Containers
• (1) CAT 2000 Owner’s Manual

The CAT 2000 controller unit scans and interprets the signals from the pH and ORP probes, displays water quality readings in digital format, and activates chemical feeders in proportion to the demand required to maintain setpoint pH and ORP levels. The unit incorporates audible and visual safeguard alarms for out of range conditions, calibration adjustment for pH, and mode selections to manually feed or disable feeding for either channel. The CAT 2000 controller unit also features an internal micro-computer for unsurpassed accuracy, adaptability, and ease of use. All user-entries and adjustments are made through the touch-screen interface front panel.

The Flow Cell provides a convenient location for mounting the pH, ORP and Flow Sensor while ensuring ideal hydraulic conditions to maximize sensor performance and life.

The Flow Sensor (required) monitors the rate of flow across the pH and ORP sensors and signals the controller to disable automated chemical feeding during periods when the filtration system is off or low recirculation flow is detected.

The Professional-Series pH Sensor samples water from the filtration system and sends signals to the controller indicating the acidity of the water. The ideal pH range for pools and spas is 7.4 - 7.6. The CAT 2000 controller is preset from the factory to maintain pH 7.5. If pH is maintained below 7.4 (too acidic), eye irritation, corrosion of equipment, and damage to the pool or spa surface can occur. If pH is maintained above 7.6 (too alkaline), sanitizer activity is reduced, water may become cloudy, and eye irritation may result.

The Professional-Series ORP Sensor samples water from the filtration system and sends signals to the controller indicating the oxidation-reduction potential (redox) of the water. ORP is an actual measure of sanitizer activity (chlorine, bromine, ozone, etc.) and bacteriological water quality rather than an expression of chemical residual levels. The CAT 2000 controller is preset from the factory to maintain ORP at 650 millivolts.
