Description
The Signet 4150 Turbidimeter system provides accurate and reliable compliant water quality monitoring for municipal and industrial applications.
The 4150 measures turbidity via a 90 degree light which reflects particles as they flow through a small volume, low flow glass cuvette. Air bubbles are eliminated from the cuvette by adjusting the backpressure valve on the outlet tube. The cuvette is located in a watertight dark chamber for continuously accurate on-line measurement. A replaceable desiccant pack provides a dry-stable environment to ensure reliable measurements.
Simple and fast calibration can be accomplished in under five minutes by placing the in-line glass cuvette from the measuring chamber into the cuvette holder while still in service and the inlet and outlet tubing remains connected. The inexpensive calibration standard allows for dry and multiple system calibrations without mixing chemicals. After calibration, the unit is up and running with simple reinsertion of the glass cuvette back into the measuring chamber.
Additional features include a message indicator when the desiccant needs replacing and as an option, auto/ultrasonic cleaning of the glass in-line cuvette for longer runs between maintenance.
The 4150 is available in two measuring ranges. The 0 to 100 NTU/FNU version is for low range applications such as drinking water. The 0 to 1000 NTU/FNU range can be used for various applications including raw water and wastewater reclamation.
