Chemtrol 250 ORP/pH Digital Controller
The CHEMTROL® 250 ORP/pH Digital Controller is a microprocessor-based digital controller designed to maintain both sanitizer ORP (oxidation-reduction potential or Redox) and water pH in high-end residential pools, small commercial pools and spas, and light industrial applications. Designed for affordability, simplicity of installation, ease of use and long-term reliability, it includes features normally not found on this type of controller such as adjustable set points, high and low alarms, overfeed safety timers and proportional feed control.EASY TO USE
A bright LCD display shows ORP and/or pH readings, calibration adjustments and alarm limits. The five LED lights indicate the operating modes (OFF, Manual or Auto), feed status, out-of-range alarms and overfeed alarms. The front panel controls include set point, calibration, low and high alarm limits, safety timer limit and proportional feed adjustment. Feed control is either ON/OFF or Proportional. The Proportional Feed feature is particularly useful to avoid overfeeding in small bodies of water. It reduces the feed cycle time progressively as the sensor reading approaches the set point.
SIMPLE AND RELIABLE
All CHEMTROL controllers are user-friendly, reliable and easy to install and operate. Every unit is supplied with a comprehensive operation manual and a FIVE-YEAR electronics warranty.
