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
