The GF Signet 4150 turbidimeter system provides accurate and reliable EPA-compliant water quality monitoring for municipal and industrial applications.

The GF Signet 4150 turbidimeter measures turbidity via a 90 degree light which reflects particles as they flow through the small volume, low flow glass cuvette. Air bubbles are eliminated in the cuvette by adjusting the backpressure valve on the GF Signet 4150 turbidimeter's outlet tube. The cuvette is located in a watertight dark chamber for continuously accurate on-line measurement. A replaceable desiccant pack provides stable environment to ensure reliable measurements.

Simple and fast calibration of the GF Signet 4150 turbidimeter can be accomplished in under five minutes by placing the glass cuvette from the measuring chamber into the cuvette holder, while the inlet and outlet tubing is still connected. The inexpensive calibration standard allows for dry and multiple system calibrations without mixing chemicals. After calibration, the GF Signet 4150 turbidimeter is up and running with a simple insertion of the glass cuvette into the measuring chamber.

Additional features of the GF Signet 4150 turbidimeter include a message indicator when the desiccant needs replacing and auto / ultrasonic cleaning of the glass cuvette for reduced maintenance.

The GF Signet 4150 turbidimeter is available in two measuring ranges. The 0 to 100 NTU version is for low range applications such as drinking water. The 0 to 1000 NTU range can be used for various applications including raw water and wastewater.

Applications for the GF Signet 4150 Turbidimeter:

  • Membrane Filtration
  • Monitoring Filter Performance
  • Raw or Filtered Water
  • Municipal Water Distribution
  • Wastewater Effluent

Here's how some of our customers use this product...

Easy, Low Cost Calibration as Compared to Competitor Units

The Background: A water treatment plant has a number of turbidity meters that must be regularly calibrated and they need a meter with a more efficient calibration process.

The Problem: The customer’s previous turbidity meters required formazine be put into the unit which was expensive, time-consuming and resulted in significant downtime for the turbidity meters.

The Solution: The GF Signet 4150 Turbidimeter offers outstanding performance along with simple calibration. The 4150 is calibrated using premixed solutions in sealed cuvettes and can be done in under 5 minutes without taking the system offline. The customer can calibrate multiple units with a single calibration kit in much less time, with less waste and no downtime. The customer has ordered multiple 4150 units and is happy with the results.
