Q45P/R pH/ORP Monitor

The differential-style sensors are designed for long sensing life in process conditions that quickly degrade traditional-style sensors. Sensor mounting configurations include 1”NPT convertible, hot-tap, and sanitary-style. The monitor is available as a loop-powered transmitter or a 115/230 VAC analyzer with dual analog outputs and dual relays. Auto-Clean and portable configurations are also available.

Q45CT Toroidal Conductivity Monitor

Toroidal conductivity sensing technology utilizes an anti-fouling jacket material to virtually eliminate sensor cleaning. Sensors are available with Polypropylene, Kynar, or PEEK material to ensure chemical resistance to corrosive chemicals. The monitor is available as a loop-powered transmitter or a 115/230 VAC analyzer with dual analog outputs and dual relays.

Q45H Free & Combined Chlorine Monitor

On-line monitoring of either free chlorine or chloramines is possible without the need for reagents. The Series Q45H is ideal for either free or chloramine treated potable water applications, or for non-nitrified wastewater effluents. An special high range is available for food processing applications where high chlorine levels must be maintained.

Q45D Dissolved Oxygen Monitor

D.O. monitoring in wastewater aeration systems, effluent channels, or natural waters are easily handled by this on-line monitoring instrument. A reliable galvanic oxygen sensor provides stable and rapid response to dissolved oxygen levels, and is easy to operate and maintain. Auto-Clean and portable configurations are also available.
