Shark-120/240 Controllers

NOTE: The Shark-120 and Shark-240 are now both replaced by the 2250. We will continue to service existing Shark controllers and will sell them until supplies run out. Call for more information.


The Shark is designed to be the most flexible, easy to use, and easy to see multi-parameter controller on the market. Select the parameter you wish to measure from the easy-to-use LCD menu on the inside front cover. Choose pH, ORP, Conductivity or Flow. The Shark features a hidden display for setting the parameter and that flips out for easy access. A universal mounting kit is included for surface, panel, and pipe-mount applications.

The Shark is an AC powered analyzer that provides two isolated, independent and scalable 4-20 mA outputs and two control relays. A third relay is preset to act as an alarm relay, but can be used as a process control relay. It has both high and low adjustable off and on set-points. Both control relays can be set for either a rising or falling process, with easily programmed on/off set-points. Each control relay has a built-in independent cycle timer, with field-set on and off time to reduce chemical overshoot. The Shark is housed in a rugged NEMA 4x polycarbonate enclosure, making it ideally suited for heavy-duty applications.
