Adjust the pH with this CO2 feed system

| By Mary Page Bailey and Gerald Ondrey

The new CO2 Feed System (photo) is a safe and effective way to adjust pH and minimize risk associated with dangerous mineral acids. The 0–100% scaled flowmeter has an integral adjustment needle valve for increased accuracy. Additional benefits of the CO2 Feed System include a NEMA 4X enclosure, illuminated on/off switch, a flow setpoint indicator, stainless-steel solenoid valve and simple push-tight tubing connectors. The CO2 Feeder is said to be an affordable and reliable system that is simple to use and adjust. — Blue-White Industries, Inc., Huntington Beach, Calif.
