Water Quality Sensors - Turbidity Meter & More

Portable turbidity meter

Portable Turbidity Meter, Colorimeter, and pH/ORP Meter

Highly precise and resilient, the multi-detector optical system effectively compensates for sample color, light fluctuations, and stray light. This capability ensures accurate readings, even in challenging sample matrices or applications.

Accurate & Durable

Poilcontrol’s turbidity meters are not only crafted for laboratory-grade accuracy but also built to withstand the rigors of the field. For instance, our unit is waterproof, guaranteeing a durable and reliable device for an extended period. Its unique design protects the electronics from moisture and corrosion. Our portable turbidity meter will float if it’s dropped in water.

No Lamp Replacement

Thanks to our durable lamps, you can say goodbye to replacing lamps in your turbididy meter. The lamps in this unit last an impressive 36 years.

In-line turbidity meter for a variety of applications

"Turb Track" Process Turbidity Meter

Produced for drinking water wastewater and reservoir water, it has also been incorporated into food & beverage applications. By containing a multi-sensor design, this ensures excellent precision and sensitivity at low levels while reducing variability between measurements.

Simple Calibration:

Benefit from this rapid calibration/verification process and a low maintenance unit. One calibration kit works for multiple units, saving time and money.

Easy calibration made possible by inserting a sample cell into the unit for reference. This allows for accurate readings on the in-line turbidity meter.
