Chemtrol 250

Affordable and Reliable Chemical Automation

The CHEMTROL® 250 controller is based on 20+ years of experience in pool and spa automation with over 25,000 installations worldwide. Featuring a 5-year electronics warranty, it actually pays for itself in 1 to 2 years through cost savings in operating and maintenance expenses.

Savings continue to accrue from the more efficient use of chemicals, avoiding over- and underfeeding, and from lower labor costs for water testing and repairs of damaged equipment. In particular, commercial operators save on specialty chemicals, customer complaints and health department shutdowns.

The CHEMTROL® 250 ORP/pH Digital Controller automatically maintains both sanitizer ORP (oxidation-reduction potential or Redox) and water pH in pools and spas.

PPM/pH  Digital CONTROLLER with Free Chlorine Control

The CHEMTROL® 255 PPM/pH Digital Controller introduces the new sensor for Free Chlorine control in automated water treatment.
