ProCon® D500 & D520 Series pH & ORP Controllers

The ProCon® D500 & D520 series is an extremely robust industrial pH & ORP controller. The modular design is easy to install and operate. It is excellent for process control, water quality, sanitization and neutralization systems, effluent monitoring, pool and spa control, aquatic animal systems, and cooling towers. It provides first measurement values in under one minute. The controller includes all the extra features; there is no need to pay extra for a relay, 4-20mA, or RS485 outputs. The SimpICal® feature makes calibrating the sensor easier and quicker than ever, and the cost-saving quick and straightforward setup is done through the user-friendly step-by-step on-screen menu. Active display of red alarm LED provides notification of out-of-bounds sensor readings and indication for sensor cleaning, recalibration, or replacement. The controller is packaged in a rugged polycarbonate enclosure, ideally suited for heavy-duty applications. A mounting kit is included for surface and panel mounting. Pipe mounting kits are available; call us for a quote. Note: All electrical connections should be checked before use.
